Scientific career

Arun Kumar Biswas (6 July 1934 – 30 November 2015) was a professor at Indian Institute of Technology, Kanpur (India) during 1963–95. He is well known for his contributions in the area of mineral engineering, archeaometallurgy, minerals and gems in antiquity, history of science, philosophy, science and music, etc. Biswas was the founding member of Indian Institute of Mineral Engineers (1969). Founder president of Indian Language Society in the early 1980s at IIT/K, he served several organizations in various honorary capacities: Mahendralal Sircar Research Professor in History of Science at the Asiatic Society, Kolkata (1995–2001); the AICTE Emeritus Fellow at the Jadavpur University (2001–2004); and INSA Research Fellow in Kolkata. He was a member of the INSA National Commission for History of Science and, the editorial board member of the Indian Journal of the History of Science.

Early years and education

After his initial studies at Saint Xaviers College (1948–52), he went on to Science College (1952–59) (both in Calcutta) to complete his Master and Doctorate degrees in Applied Chemistry. He submitted his doctoral thesis (1959) on surface-active agents from glycerides and their fascinating micellar world in aqueous solutions. Inspired by the advice of his mentor, Dr. K.K. Majumdar (who later became the founding President of the Indian Institute of Mineral Engineers (IIME)), Biswas took up mineral engineering as one of the goals of his professional career and the study of the challenging subject of froth flotation which involved the investigations related to surface science, one of his passions. In his own words, ‘... (he) contacted Professor AM Gaudin of MIT and was warmly invited ... and then opened before him the glamorous world of MIT education in several fields: mineralogy and crystallography (William Dennen and Martin Burger), optical mineralogy (GE Agar), mineral engineering (AM Gaudin), physical chemistry of surfaces (PL de Bruyn and Alan Michaels) and even archaeometallurgy (the famous CS Smith) and history of science and civilization (guess who, Aldous Huxley who was a Visiting Professor during the Centenary year of 1961)!’ He went to MIT as a Fulbright Fellow. At MIT (1960–63), he worked on hysteresis of contact angle under the guidance of Professor Antoine Marc Gaudin. Learning at MIT was not confined to science of mineral processing; he continued with his interest in music, which he developed in early fifties, and simultaneously attended a course in Music Department on 'Music Appreciation'.

IIT Kanpur era (1963–95)

Professor Biswas returned to India in 1963 and joined Department of Metallurgical Engineering (now Materials and Metallurgical Engineering) at the Indian Institute of Technology, Kanpur. He was the founding members of the Department where he served as a faculty member during (1963–95).

Contributions to mineral processing

The essence of his early years at IIT Kanpur can be gauged from his personal recollection, 'During the period 1964–1970, Biswas was extremely busy in organising the mineral engineering programme at IIT Kanpur in collaboration with his esteemed colleagues: TC Rao who had worked with Professor AJ Lynch in Australia, A Ghosh who had worked with Professor TB King at MIT, and the two geologist colleagues: KVGK Gokhale who wrote a book on mineral resources in India, co-authored by TC Rao, and BC Ray Mahasay the renowned geochemist from the Harvard University. Professor Gerhard Derge had gone back to USA, but he kept on sending valuable advice to Biswas on the subject of mineral engineering ... 1968 ..., A K Biswas planned a Short Course on 'Mineral Engineering Practice' to be held at IIT Kanpur on 27 and 28 February 1969, to be followed by a Seminar on "Mineral Engineering Education" scheduled on 1 March ... An invitation was sent to Professor AM Gaudin through the KIAP (unfortunately the visit did not take place) .... Professor Gaudin's love for antiquity was very deep and infectious, imbibed by many of his students, including AK Biswas'. In 1969, he published his first book, Science in India (Firma KLM, Kolkata). Along with Dr. KK Majumdar, head of ore dressing section at BARC and several other stalwarts working in the area of mineral processing, he played a very active role in the setting up of Indian Institute of Mineral Engineers (IIME) which was registered as a Society on 12 November 1969. On his association with IIME, in 2012, he observed, 'I was proud (and still am) to become the first Life Member of the proposed institute'.

During his distinguished career of 32 years (1963–94) at IIT/K, Biswas developed and taught several courses related to mineral processing. He established the Materials Separation and Surface Chemistry laboratories. Biswas enjoyed the reputation of a dedicated teacher and was popular among students. Industrial perspective was a hallmark of his teaching. Starting from his early career, he used to visit mineral based industry/institutes almost every summer. Besides teaching, he guided many students in their research at Doctoral, Masters and Bachelors levels. Many of them are well-established professionals now in India and abroad.

Biswas believed that both basic and applied research are critical for the industry. He advocated the importance of characterisation in mineral research and collaborated with several of his colleagues in the Institute, notably Professors TR Ramachandran and Ranjit K Ray. The motivation of many of the research projects pursued under his guidance was to find innovative means of beneficiating several complex and/or low-grade Indian mineral deposits, such as monazite beach sand, zircon, molybdenite, diamond, phos¬phorites, zinc ferrite, zinc tailings and residues, alumina-rich iron ore, pyrite, separation amongst calcium mineral systems, Kudremukh-iron ore tailing, deep sea manganese nodules, ferrotungsten deposits etc. Simultaneous studies were also carried out in his laboratory on several key unit operations in mineral processing, such as comminution, froth flotation, selective flocculation, leaching and bacterial leaching . In basic research, some studies by Biswas and his coworkers received international attention; for example:
collector-frother interactions
tannin-fatty acids and starch-fatty acids interactions in calcite-fluorite flotation separation

In late seventies and eighties, Biswas and coworkers made important contributions towards characterization of mineral separation systems using XRD, SEM with X-ray microanalysis, EPMA, TEM and several spectroscopic techniques (IR, NMR, Mossbauer, etc.). The systems studied included fine grained alumina-rich Indian iron ore, Zn-containing flotation tails, Zawar ancient siliceous slag and retorts, and ferromanganese nodules from the Indian Ocean and their synthetic analogues, chalcopyrite, and synthetic tungsten minerals. Biswas participated in several important international conferences such as International Mineral Processing Congresses (Cannes, 1963; Prague, 1970; Cagliari, 1975; Warsaw, 1979) and International Symposium on Surfactants, Gainesville, Florida, 1990.

Contributions to archaeometallurgy and beyond

Biswas's intellectual activities extended far beyond mineral engineering and covered languages, archaeometallurgy, minerals and gems in ancient India, literature, music and religions – mostly in the Indian context. Biswas was the founder-president of the Indian Languages Society, which organized a national seminar on Profiles in Indian languages during 10–12 December 1982. The proceedings of the seminar were published as a multi-authored book Profiles in Indian languages and literatures, which received international acclaim. The period around 1980 was also the beginning of his increasing interest in archaeometallurgy. Characterisation studies on ancient slag and retorts from Zawar mines later culminated in a number of papers on the primacy of India in brass and zinc metallurgy. During 1987–90, History of Science Division of Indian National Science Academy (INSA) sponsored a project on 'Minerals and Metals in Ancient India up to 1200 AD from Sanskrit Literature and other Sources'. In this project, he was ably assisted by his wife, Sulekha, a Sanskrit scholar. The project completion report submitted in 1991 later (in 1996) resulted in the publication of the monumental monograph called 'Minerals and Metals in Ancient India'. This two volume monograph (volume 1 – Archaeological Evidence, Volume – 2 Literary Evidence) tells the fascinating, coherently woven story of the Mineral and Metals from across the entire sub-continental sprawl of the old-world India (including Pakistan and Bangladesh). In following years (1991–94), INSA sponsored another project on Minerals and Metals in Pre-Modern period (1200–1900 AD) which led to the publication of several interesting papers in Indian J History of Science; Gem minerals in pre-Modern India, Non-Gem Minerals in Pre-modern India and Iron and Steel in Pre-modern India. Biswas delved deep into the ancient Indian texts and established the etymology of beryllium-containing minerals in the Indian and world literature – particularly of Beryl (Vaidurya) and emerald (Marakata). Similarly, other topics related to history of science included : History of science in India : In search of a new paradigm, Rasa-Ratna Samuccaya and Mineral Processing State of Art in the 13th Century A.D. India, Revered father Eugene Lafont and science activity of St Xavier's College,

During the period 1985–94, he also wrote and edited several books
Swami Vivekananda and the Indian Quest for Socialism (Firma KLM Pvt Ltd, Calcutta, 1986);
A Pilgrimage to Khetri and the Sarasvati Valley (Sujan Publications, Calcutta, 1987);
Buddha and Bodhisattva – A Hindu View (Cosmo Publications, New Delhi, 1987);
Frontiers in Applied Chemistry (edited volume, Springer Verlag, Berlin and Narosa Publishing House, New Delhi, 1989); and
Swami Vijnanananda and his Paramahamsa Carita (Sujan Publication, 1994).

The superannuation of Professor Biswas from IIT/K on 31 July 1994, marked the beginning of a new chapter in his life. He moved to Kolkata where he spent a lot more time with Ramakrishna Mission. He served several organizations in various honorary capacities for example, Mahendralal Sircar Research Professor in History of Science at the Asiatic Society, Kolkata (1995–2001); the AICTE Emeritus Fellow at the Jadavpur University (2001–2004); and INSA Research Fellow in Kolkata. He joined as a member of the INSA National Commission for History of Science and the editorial board member of the Indian Journal of the History of Science.

Post IIT Kanpur era
Research papers and book reviews

Biswas's academic interest and firm conviction that both social sciences and humanities and science and technology are essential for human progress, propelled him to publish a large number of research papers and reviews on a wide spectrum of topics. The topics covered included: Epic of Saltpetre to Gunpowder; Why did Scientific Renaissance take place in Europe and not in India; Brass and zinc metallurgy in the ancient and medieval world : India's primacy and the technology transfer to the west, Raman, Krishnan and the IACS Episodes of the 1930s; The Era of Science Enthusiasts in Bengal (1841–1891): Akshayakumar's; Vidyasagar and Rajendralala; Calcuttan Science 1784–1930 and the Awakening in India; Rammohun Roy, his Intellectual Compatriots and their Scientific Contributions; Science in the Path of Syncretism, Syncretism in the Future of Humankind – Some Golden thoughts of Swami Vivekananda; Social Factors in the Development of Technology in Ancient India; Science, Spirituality and Socialism: A Tribute to Joseph Needham; Science and Music with a Special Note on Helmholtz, James Jeans to Pandit Ravishankar. He also published some interesting book reviews, such as: Images and Contexts: The Historiography of Science and Modernity in India; Story of the Delhi Iron Pillar; The Indus Civilization, A People's History of India. Jagadish Chandra Bose and National Science; Kautilya's Arthasastra in the light of modern science and technology; An Eye For Excellence: (Fifty Innovative Years of IIT Kanpur); la vintage metallurgie (coffee table book, CSIR-NML); Caught between two Cultures – Science in Nineteenth Century Bengal, etc.

The Kodaikanal Solar Observatory in South India performed this monitoring using their recently built solar tunnel telescope. Das was the director of the Kodaikanal observatory at this time. In 1960 he was responsible for installing a tower/tunnel telescope at the facility that would be used to perform some of the first helioseismology investigations.[1] The crater Das on the far side of the Moon is named after him.


Solar Tunnel Telescope at Kodaikanal

After graduating ( Master of Science ) from the University of Calcutta, he studied spectroscopy with Charles Fabry at the Sorbonne in Paris. After obtaining his doctorate he was in Göttingen where he worked with Max Born at the Institut für Theoretische Physik and subsequently with Gustav Augenheister at the Geophysikalisches Institut and for a short period at the Solar Physics Observatory in Cambridge . He later worked at the Indian Meteorological Department in 1930 and then moved to the Kodaikanal observatory in 1937 as assistant director and director since 1946 and where he remained until his retirement in 1960.

Scientific contributions

Most of his scientific contributions were in the field of solar physics mainly as an experimenter in the spectrophotometric study of sunspots and the chromosphere . He contributed significantly to the development of the equipment present at the Kodaikanal Observatory and to the growth of numerous young researchers.

A. Lalitha, photographed in 1964 in New York.

Ayyalasomayajula Lalitha MIEE (27 August 1919 – 12 October 1979) was India's first female engineer.

Early life and education

Ayyalasomayajula Lalitha was born in Madras (now Chennai) on 27 August 1919. She was married at 15 and in 1937, gave birth to her daughter Syamala. Her husband died four months later. Her father, Pappu Subba Rao, supported her wish to complete her secondary education and study engineering at the otherwise all-male College of Engineering, Guindy(CEG) where he was a professor. At CEG, Lalitha studied alongside other women engineers P.K. Thressia and Leelamma Koshie (nee George).

Lalitha graduated in 1943 with a degree in electrical engineering - becoming India's first woman engineer. She completed her practical training with a one year apprenticeship in Jamalpur Railway Workshop, a major repair and overhaul facility.

Engineering career

After graduation, Lalitha worked at Central Standards Organisation, Shimla and helped her father research smokeless ovens and the jelectromonium (an electrical musical instrument).

She spent a year of practical training in the electrical department of the East Indian Railways, before becoming a technical assistant in the Indian Government’s Office of the Electrical Commissioner. Following this, in 1948, Lalitha joined a British firm Associated Electrical Industries (AEI) in Calcutta and worked on the largest dam in India, Bhakra Nangal Dam, designing transmission lines, and substation layouts. She worked at AEI (later taken over by General Electric Company) for nearly thirty years before she retired in 1977.

In 1953 the Council of the Institution of Electrical Engineers (IEE) of London elected her to be an associate member, and promoted her to full member in 1966.

Lalitha was the only female engineer from India to have attended the First International Conference of Women Engineers and Scientist (ICWES) in New York in 1964.

Lalitha was elected as a member of the British Women's Engineering Society in 1965 and served as the Organising Committees' India representative for the Second International Conference of Women Engineers and Scientist (ICWES) held in Cambridge in July 1967 and ensured that five women from India were able to attend.

Personal life

Lalitha did not remarry after her husband's death. She lived for most of her life with her sister-in-law who helped to bring up her daughter Syamala, who took degrees in science subjects and became a mathematics teacher.

In 1979, Lalitha died of a brain aneurysm, aged 60

The Genius Indian Mathematician-Astronomers

जन्म: 476 कुसुमपुर अथवा अस्मक
मृत्यु: 550

कार्य: गणितग्य, खगोलशाष्त्री

आर्यभट्‍ट प्राचीन समय के सबसे महान खगोलशास्त्रीयों और गणितज्ञों में से एक थे। विज्ञान और गणित के क्षेत्र में उनके कार्य आज भी वैज्ञानिकों को प्रेरणा देते हैं। आर्यभट्‍ट उन पहले व्यक्तियों में से थे जिन्होंने बीजगणित (एलजेबरा) का प्रयोग किया। आपको यह जानकार हैरानी होगी कि उन्होंने अपनी प्रसिद्ध रचना ‘आर्यभटिया’ (गणित की पुस्तक) को कविता के रूप में लिखा। यह प्राचीन भारत की बहुचर्चित पुस्तकों में से एक है। इस पुस्तक में दी गयी ज्यादातर जानकारी खगोलशास्त्र और गोलीय त्रिकोणमिति से संबंध रखती है। ‘आर्यभटिया’ में अंकगणित, बीजगणित और त्रिकोणमिति के 33 नियम भी दिए गए हैं।

आज हम सभी इस बात को जानते हैं कि पृथ्वी गोल है और अपनी धुरी पर घूमती है और इसी कारण रात और दिन होते हैं। मध्यकाल में ‘निकोलस कॉपरनिकस’ ने यह सिद्धांत प्रतिपादित किया था पर इस वास्तविकता से बहुत कम लोग ही परिचित होगें कि ‘कॉपरनिकस’ से लगभग 1 हज़ार साल पहले ही आर्यभट्ट ने यह खोज कर ली थी कि पृथ्वी गोल है और उसकी परिधि अनुमानत: 24835 मील है। सूर्य और चन्द्र ग्रहण के हिन्दू धर्म की मान्यता को आर्यभट्ट ने ग़लत सिद्ध किया। इस महान वैज्ञानिक और गणितग्य को यह भी ज्ञात था कि चन्द्रमा और दूसरे ग्रह सूर्य की किरणों से प्रकाशमान होते हैं। आर्यभट्ट ने अपने सूत्रों से यह सिद्ध किया कि एक वर्ष में 366 दिन नहीं वरन 365.2951 दिन होते हैं।

प्रारंभिक जीवन

आर्यभट्ट ने अपने ग्रन्थ ‘आर्यभटिया’ में अपना जन्मस्थान कुसुमपुर और जन्मकाल शक संवत् 398 (476) लिखा है। इस जानकारी से उनके जन्म का साल तो निर्विवादित है परन्तु वास्तविक जन्मस्थान के बारे में विवाद है। कुछ स्रोतों के अनुसार आर्यभट्ट का जन्म महाराष्ट्र के अश्मक प्रदेश में हुआ था और ये बात भी तय है की अपने जीवन के किसी काल में वे उच्च शिक्षा के लिए कुसुमपुरा गए थे और कुछ समय वहां रहे भी थे। हिन्दू और बौध परम्पराओं के साथ-साथ सातवीं शताब्दी के भारतीय गणितज्ञ भाष्कर ने कुसुमपुरा की पहचान पाटलिपुत्र (आधुनिक पटना) के रूप में की है। यहाँ पर अध्ययन का एक महान केन्द्र, नालन्दा विश्वविद्यालय स्थापित था और संभव है कि आर्यभट्ट इससे जुड़े रहे हों। ऐसा संभव है कि गुप्त साम्राज्य के अन्तिम दिनों में आर्यभट्ट वहां रहा करते थे। गुप्तकाल को भारत के स्वर्णिम युग के रूप में जाना जाता है।


आर्यभट्ट के कार्यों की जानकारी उनके द्वारा रचित ग्रंथों से मिलती है। इस महान गणितग्य ने आर्यभटिय, दशगीतिका, तंत्र और आर्यभट्ट सिद्धांत जैसे ग्रंथों की रचना की थी। विद्वानों में ‘आर्यभट्ट सिद्धांत’ के बारे में बहुत मतभेद है । ऐसा माना जाता है कि ‘आर्यभट्ट सिद्धांत’ का सातवीं शदी में व्यापक उपयोग होता था। सम्प्रति में इस ग्रन्थ के केवल 34 श्लोक ही उपलब्ध हैं और इतना उपयोगी ग्रंथ लुप्त कैसे हो गया इस विषय में भी विद्वानों के पास कोई निश्चित जानकारी नहीं है।


आर्यभटीय उनके द्वारा किये गए कार्यों का प्रत्यक्ष विवरण प्रदान करता है। ऐसा माना जाता है कि आर्यभट्ट ने स्वयं इसे यह नाम नही दिया होगा बल्कि बाद के टिप्पणीकारों ने आर्यभटीय नाम का प्रयोग किया होगा। इसका उल्लेख भी आर्यभट्ट के शिष्य भास्कर प्रथम ने अपने लेखों में किया है। इस ग्रन्थ को कभी-कभी आर्य-शत-अष्ट (अर्थात आर्यभट्ट के 108 – जो की उनके पाठ में छंदों कि संख्या है) के नाम से भी जाना जाता है। आर्यभटीय में वर्गमूल, घनमूल, समान्तर श्रेणी तथा विभिन्न प्रकार के समीकरणों का वर्णन है। वास्तव में यह ग्रन्थ गणित और खगोल विज्ञान का एक संग्रह है। आर्यभटीय के गणितीय भाग में अंकगणित, बीजगणित, सरल त्रिकोणमिति और गोलीय त्रिकोणमिति शामिल हैं। इसमे सतत भिन्न (कँटीन्यूड फ़्रेक्शन्स), द्विघात समीकरण (क्वड्रेटिक इक्वेशंस), घात श्रृंखला के योग (सम्स ऑफ पावर सीरीज़) और ज्याओं की एक तालिका (Table of Sines) शामिल हैं। आर्यभटीय में कुल 108 छंद है, साथ ही परिचयात्मक 13 अतिरिक्त हैं। यह चार पदों अथवा अध्यायों में विभाजित है:


आर्य-सिद्धांत खगोलीय गणनाओं के ऊपर एक कार्य है। जैसा कि ऊपर बताया जा चुका है, यह ग्रन्थ अब लुप्त हो चुका है और इसके बारे में हमें जो भी जानकारी मिलती है वो या तो आर्यभट्ट के समकालीन वराहमिहिर के लेखनों से अथवा बाद के गणितज्ञों और टिप्पणीकारों जैसे ब्रह्मगुप्त और भास्कर प्रथम आदि के कार्यों और लेखों से। हमें इस ग्रन्थ के बारे में जो भी जानकारी उपलब्ध है उसके आधार पर ऐसा प्रतीत होता है कि यह कार्य पुराने सूर्य सिद्धांत पर आधारित है और आर्यभटीय के सूर्योदय की अपेक्षा इसमें मध्यरात्रि-दिवस-गणना का उपयोग किया गया है। इस ग्रन्थ में ढेर सारे खगोलीय उपकरणों का भी वर्णन है। इनमें मुख्य हैं शंकु-यन्त्र, छाया-यन्त्र, संभवतः कोण मापी उपकरण, धनुर-यन्त्र / चक्र-यन्त्र, एक बेलनाकार छड़ी यस्ती-यन्त्र, छत्र-यन्त्र और जल घड़ियाँ।

उनके द्वारा कृत एक तीसरा ग्रन्थ भी उपलब्ध है पर यह मूल रूप में मौजूद नहीं है बल्कि अरबी अनुवाद के रूप में अस्तित्व में है – अल न्त्फ़ या अल नन्फ़। यह ग्रन्थ आर्यभट्ट के ग्रन्थ का एक अनुवाद के रूप में दावा प्रस्तुत करता है, परन्तु इसका वास्तविक संस्कृत नाम अज्ञात है। यह फारसी विद्वान और इतिहासकार अबू रेहान अल-बिरूनी द्वारा उल्लेखित किया गया है।

आर्यभट्ट का योगदान

आर्यभट का भारत और विश्व के गणित और ज्योतिष सिद्धान्त पर गहरा प्रभाव रहा है। भारतीय गणितज्ञों में सबसे महत्वपूर्ण स्थान रखने वाले आर्यभट ने 120 आर्याछंदों में ज्योतिष शास्त्र के सिद्धांत और उससे संबंधित गणित को सूत्ररूप में अपने प्रसिद्ध ग्रंथ ‘आर्यभटीय’ में प्रस्तुत किया है।

उन्होंने गणित के क्षेत्र में महान आर्किमिडीज़ से भी अधिक सटीक ‘पाई’ के मान को निरूपित किया और खगोलविज्ञान के क्षेत्र में सबसे पहली बार यह घोषित किया गया कि पृथ्वी स्वयं अपनी धुरी पर घूमती है।

स्थान-मूल्य अंक प्रणाली आर्यभट्ट के कार्यों में स्पष्ट रूप से विद्यमान थी। हालांकि उन्होंने शुन्य दर्शाने के लिए किसी प्रतीक का प्रयोग नहीं किया, परन्तु गणितग्य ऐसा मानते हैं कि रिक्त गुणांक के साथ, दस की घात के लिए एक स्थान धारक के रूप में शून्य का ज्ञान आर्यभट्ट के स्थान-मूल्य अंक प्रणाली में निहित था।

यह हैरान और आश्चर्यचकित करने वाली बात है कि आजकल के उन्नत साधनों के बिना ही उन्होंने लगभग डेढ़ हजार साल पहले ही ज्योतिषशास्त्र की खोज की थी। जैसा कि हम पहले ही बता चुके हैं, कोपर्निकस (1473 से 1543 इ.) द्वारा प्रतिपादित सिद्धांत की खोज आर्यभट हजार वर्ष पहले ही कर चुके थे। “गोलपाद” में आर्यभट ने सर्वप्रथम यह सिद्ध किया कि पृथ्वी अपने अक्ष पर घूमती है।

इस महान गणितग्य के अनुसार किसी वृत्त की परिधि और व्यास का संबंध 62,832 : 20,000 आता है जो चार दशमलव स्थान तक शुद्ध है। आर्यभट्ट कि गणना के अनुसार पृथ्वी की परिधि 39,968.0582 किलोमीटर है, जो इसके वास्तविक मान 40,075.0167 किलोमीटर से केवल 0.2 % कम है।

The greatest scientist of India was a dalit
('where there is a will there is a way')
 by Ultimate Dalit

It is true that the great astronomer-mathematician-scientist of India Aryabhata was a dalit. Although 'bhatta' implies a brahmin, Aryabhata spells his own name as 'bhata' in his writings and this is also how he is spelled by other Indian scientists like Varahmira and Brahmagupt in their works. Now the name 'bhata' implies a dalit.

Since dalits were not getting an education in Aryabhata's days how did he manage to become such a great scientist? The speculative answer is: by becoming a budhist. There was a physician-scientist called Vagabhata who made original contributions to Indian medicine and is believed to have been a dalit who later converted to Budhism. Presumably, Aryabhata was also able to gain a good education by the same method.

This reminds one of the old adage 'where there is a will there is a way'.

Alternative Titles: Aryabhata I, Aryabhata the Elder

Aryabhata, also called Aryabhata I or Aryabhata the Elder, (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

Aryabhatasiddhanta circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).

In Ganita Aryabhata names the first 10 decimal places and gives algorithms for obtaining square and cubic roots, using the decimal number system. Then he treats geometric measurements—employing 62,832/20,000 (= 3.1416) for π—and develops properties of similar right-angled triangles and of two intersecting circles. Using the Pythagorean theorem, he obtained one of the two methods for constructing his table of sines. He also realized that second-order sine difference is proportional to sine. Mathematical series, quadratic equations, compound interest (involving a quadratic equation), proportions (ratios), and the solution of various linear equations are among the arithmetic and algebraic topics included. Aryabhata’s general solution for linear indeterminate equations, which Bhaskara I called kuttakara (“pulverizer”), consisted of breaking the problem down into new problems with successively smaller coefficients—essentially the Euclidean algorithm and related to the method of continued fractions.

With Kala-kriya Aryabhata turned to astronomy—in particular, treating planetary motion along the ecliptic. The topics include definitions of various units of time, eccentric and epicyclic models of planetary motion (see Hipparchus for earlier Greek models), planetary longitude corrections for different terrestrial locations, and a theory of “lords of the hours and days” (an astrological concept used for determining propitious times for action).

Aryabhatiya ends with spherical astronomy in Gola, where he applied plane trigonometry to spherical geometry by projecting points and lines on the surface of a sphere onto appropriate planes. Topics include prediction of solar and lunar eclipses and an explicit statement that the apparent westward motion of the stars is due to the spherical Earth’s rotation about its axis. Aryabhata also correctly ascribed the luminosity of the Moon and planets to reflected sunlight.

The Indian government named its first satellite Aryabhata (launched 1975) in his honour.

Aryabhata Biography

Aryabhata was an ancient Indian mathematician-astronomer. This biography profiles his childhood, life, works, achievements and timeline.

Quick Facts
Born: 476
Nationality: Indian
Famous: Astronomers Mathematicians
Died At Age: 74
Born in: Assaka
Died on: 550

Aryabhata was an acclaimed mathematician-astronomer. He was born in Kusumapura (present day Patna) in Bihar, India. His contribution to mathematics, science and astronomy is immense, and yet he has not been accorded the recognition in the world history of science. At the age of 24, he wrote his famed “Aryabhatiya”. He was aware of the concept of zero, as well as the use of large numbers up to 1018. He was the first to calculate the value for ‘pi’ accurately to the fourth decimal point. He devised the formula for calculating areas of triangles and circles. He calculated the circumference of the earth as 62,832 miles, which is an excellent approximation, and suggested that the apparent rotation of the heavens was due to the axial rotation of the earth on its axis. He was the first known astronomer to devise a continuous counting of solar days, designating each day with a number. He asserted that the planets shine due to the reflection of sunlight, and that the eclipses occur due to the shadows of moon and earth. His observations discount the “flat earth” concept, and lay the foundation for the belief that earth and other planets orbit the sun.

Childhood & Early Life

Aryabhata’s birthplace is uncertain, but it may have been in the area known in ancient texts as Ashmaka, which may have been Maharashtra or Dhaka or in Kusumapura in present day Patna.

Some archaeological evidence suggests that he came from the present day Kodungallur, the historical capital city of Thiruvanchikkulam of ancient Kerala - this theory is strengthened by the several commentaries on him having come from Kerala.

He went to Kusumapura for advanced studies and lived there for some time. Both Hindu and Buddhist traditions, as well as Bhāskara I, the 7th Century mathematician, identify Kusumapura as modern Patna.

Career & Later Life

A verse mentions that Aryabhata was the head of an institution (kulapa) at

Kusumapura. Since, the University of Nalanda was in Pataliputra, and had an astronomical observatory; it is probable that he was its head too.

Direct details of his work are known only from the Aryabhatiya. His disciple Bhaskara I calls it Ashmakatantra (or the treatise from the Ashmaka).

The Aryabhatiya is also occasionally referred to as Arya-shatas-aShTa (literally, Aryabhata’s 108), because there are 108 verses in the text. It also has 13 introductory verses, and is divided into four pādas or chapters.

Aryabhatiya’s first chapter, Gitikapada, with its large units of time — kalpa, manvantra, and Yuga — introduces a different cosmology. The duration of the planetary revolutions during a mahayuga is given as 4.32 million years.

Ganitapada, the second chapter of Aryabhatiya has 33 verses covering mensuration (kṣetra vyāvahāra), arithmetic and geometric progressions, gnomon or shadows (shanku-chhAyA), simple, quadratic, simultaneous, and indeterminate equations.

Aryabhatiya’s third chapter Kalakriyapada explains different units of time, a method for determining the positions of planets for a given day, and a seven-day week with names for the days of week.

The last chapter of the Aryabhatiya, Golapada describes Geometric/trigonometric aspects of the celestial sphere, features of the ecliptic, celestial equator, shape of the earth, cause of day and night, and zodiacal signs on horizon.

He did not use a symbol for zero; its knowledge was implicit in his place-value system as a place holder for the powers of ten with null coefficients.

He did not use the Brahmi numerals, and continued the Sanskritic tradition from Vedic times of using letters of the alphabet to denote numbers, expressing quantities in a mnemonic form.

He worked on the approximation for pi thus — add four to 100, multiply by eight, and then add 62,000, the circumference of a circle with a diameter of 20,000 can be approached.

It is speculated that Aryabhata used the word āsanna (approaching), to mean that not only is this an approximation, but that the value is incommensurable or irrational.

In Ganitapada, he gives the area of a triangle as: “for a triangle, the result of a perpendicular with the half-side is the area”. He discussed ‘sine’ by the name of ardha-jya or half-chord.

Like other ancient Indian mathematicians, he too was interested in finding integer solutions to Diophantine equations with the form ax + by = c; he called it the kuṭṭaka (meaning breaking into pieces) method.

His contribution to the study of Algebra is immense. In Aryabhatiya, Aryabhata provided elegant results for the summation of series of squares and cubes through well tried formulae.

His system of astronomy was called the audayaka system, in which days are reckoned from uday, dawn at lanka or “equator”. His later writings, which apparently proposed the ardha-rAtrikA, or midnight model, are lost.

He correctly believed that the earth rotates about its axis daily, and that the apparent movement of the stars is a relative motion caused by the rotation of the earth, challenging the prevailing view.

In Aryabhatiya, he writes that ‘setting and rising of planets’ is a perception similar to that of someone in a boat going forward sees an unmoving (object) going backward.

He correctly asserted that the planets shine due to the reflection of sunlight, and that the eclipses occur due to the shadows of moon and earth, and not caused by a demon called “Rahu”!

He correctly deduced that the orbits of the planets are ellipses; this is another great discovery not credited to him but to Johannes Kepler (a German astronomer, born AD 1571).

Major Works

Aryabhata’s major work, Aryabhatiya, a compendium of mathematics and astronomy, was extensively referred to in the Indian mathematical literature, and has survived to modern times. The Aryabhatiya covers arithmetic, algebra, and trigonometry.

Personal Life & Legacy

Aryabhata’s work was of great influence in the Indian astronomical tradition and influenced several neighboring cultures through translations. Some of his works are cited by Al-Khwarizmi, and in the 10th century by Al-Biruni.

The Aryabhata Knowledge University (AKU), Patna, has been established by the Government of Bihar in his honor for the development and management of educational infrastructure related to technical, medical, management and allied professional education.
India’s first satellite Aryabhata is named in his honor.
At the Aryabhata Research Institute of Observational Sciences (ARIOS) near Nainital, India, research in astronomy, astrophysics and atmospheric sciences is conducted.


Named after the great Indian astronomer of the same name, India’s first satellite’s image used to appear on the reverse of Indian 2 rupee banknotes.
Named after the great Indian astronomer is the remnant of a lunar impact crater located in the eastern Sea of Tranquility on the Moon. Submerged by lava-flow, now only an arc-shaped ridge remains.

Adinath Lahiri (1916–1975) was an Indian geochemist and fuel technologist, known for his efforts in developing Central Fuel Research Institute, Dhanbad (CFRI) into one of the premier research institutions in India. He was the director of the National Coal Development Corporation (NCDC) and contributed towards the establishment of the Central Mining Research Station, which was later merged with CFRI to form the present day Central Institute of Mining and Fuel Research). The Government of India awarded him the fourth highest civilian honour of the Padma Shri in 1960 and followed it up with the third highest honour of the Padma Bhushan, in 1969, for his contributions to Science and Technology.


Adinath Lahiri was born on 24 August 1916. After completing his master's degree in geology and geochemistry from the University of Calcutta, he obtained Sir Palit Foreign Fellowship of the university and did his doctoral studies at the Imperial College of the University of London to secure a PhD, winning the Judd Memorial Prize for the best thesis in geochemistry. He started his career as a research associate at the Department of Chemical Technology at Imperial College in 1942, but joined the Royal Air Force during World War II to serve as a Scientific Officer and, later, as the Head of the Fuel and Oil Research Section at the Royal Aircraft EstablishmentFarnborough airfield. After the war was over, he returned to India, in 1945, to take up the position as the Assistant Director (Planning) at the Council of Scientific and Industrial Research (CSIR) when he contributed to the planning and establishment of the Central Fuel Research Institute (CFRI), Dhanbad. He joined the institute after its inception as the Deputy Director and when the founder director, J. W. Whitteker left, he took over as the director in 1953 to stay with the institute till his superannuation in 1974. In between, he also underwent training under a Summer Fellowship at the Massachusetts Institute of Technology School of Science in 1950. After his retirement from CFRI, he joined the United Nations as an advisor and served in Chile when he died on 26 August 1975, two days after his 60th birthday, succumbing to a cardiac arrest.

Lahiri's research interests covered the fields of petrography, oxidation mechanisms, solvent extraction, surface chemistry of coal, catalysts and adsorbents and he was credited with several innovations in fuel technology, which earned him over 90 patents. His contributions have been reported in the development of beehive coke oven, process technologies for the isolation and recovery of useful chemicals from the byproducts of coal, process technologies for the production of resins and other compounds, and active carbon and ion exchangers for determination of water-based coal. He published his research and professional experiences by way of over 500 articles, Reaction of coals under plasma conditions: direct production of acetylene from coal, National Coal Development Corporation A New Approach, and Trekking on the Southern Bhutan Frontier counting among them. During his tenure with CFRI, he proposed the setting up of Central Mining Research Station for overcoming the coal mining issues faced in India and served as the director of the National Coal Development Corporation. In 1954, he proposed energy studies, a pioneering effort in India, and served the Indian Energy Survey Committee of 1965 and the National Fuel Policy Committee of 1974, as a member.

Lahiri was an elected Fellow of the Institution of Engineers, Institute of Fuels (London) and the Indian National Science Academy (INSA), and served as a member of the INSA council from 1968 to 1970. In 1960, the Government of India awarded him the fourth highest civilian honour of the Padma Shri. Nine years later, he was included in the Republic Day Honours list again, this time for the third highest honour of the Padma Bhushan.[3] Central Fuel Research Institute, the institute he helped found, have since renamed their conferencing facility as Adinath Lahiri Hall, in his honour.

His post-doctoral work was also at Scripps Institution and on his return to India, he joined Oceanography and Climate Studies Area, Earth Sciences and Solar System Division of Physical Research Laboratory (PRL) in 1972. He served the institution for the whole of his career till his superannuation in 1997 and post-retirement, he continues his association with PRL as an honorary professor and a CSIR Emeritus Scientist.


Somayajulu is known to have done extensive researches on the physico-chemical reactions within the oceans and the water-sediment interface and has developed many research methodologies which include the nuclear methods for the determination of the growth rates of manganese nodules, advection-diffusion mixing of ocean waters, cosmic ray-produced 32Si and 10Be in studies for determining the calculation of sediment accumulation rates and geochemical methods for studying reactive elements in sea water. He conducted beryllium-10 studies on manganese nodules which helped establish the slow rate of growth of the nodules.His researches have been documented as chapter in a book, The Indian Human Heritage, and as several peer-reviewed articles, the article repository of the Indian Academy of Sciences has listed 100 of them. He has also edited a book, From Mantle to Meteorites: A Garland of Perspectives - A Festschrift for Devendra Lal, published by Indian Academy of Sciences in 1990 and his work has been cited by several authors.

Somayajulu served as the chief scientist for many studies conducted in the Arabian Sea and the Bay of Bengal and was a part of the Antipode expedition to the South Pacific and the GEOSECS Indian Ocean Expedition. He was among the scientists who established the Accelerator Mass Spectrometry Facility at the Institute of Physics, Bhubaneswar. He has been a member of the governing council of the National Centre for Antarctic and Ocean Research, the research advisory committee of the Department of Ocean Development, and the executive committee of the International Association of Physical Sciences of the Ocean (IAPSO). He has been involved in the organization of many seminars, served as a member of the Indian National Science Academy during 1988–90 and has mentored 7 doctoral scholars in their studies.

Awards and honors

The Council of Scientific and Industrial Research awarded Somayajulu the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards, in 1978. He received the Hari Om Ashram Prerit Award in Oceanology in 198 and the National Award for Ocean Science and Technology of Ministry of Earth Sciences in 2006. The Indian Academy of Sciences also elected him as a fellow in 1980 and the Indian National Science Academy followed suit three years later. He became an elected fellow of the National Academy of Sciences, India, American Geophysical Union and the European Association of Geochemistry in 1989, 2003 and 2004 respectively. He is also a fellow of the Geological Society of India and the Indian Geophysical Union. The award orations delivered by him include Jawaharlal Nehru Birth Centenary Lecture Award of the Indian National Science Academy in 1997 and the Prof. K.

Bunyan Edmund Vijayam (1933–2019) was an Indian geologist with major contribution to the field of Geology. A 1958–1959 Technical Report of the Council of Scientific and Industrial Research heralded the news that new developments had taken place in scientific matters led by a team of researchers at the Andhra University,

A new technique for the ion-exchange separation of uranium from thorium and rare earths has been developed. A simple chromatographic method for the estimation of thorium (present in very small quantities) has been evolved. This utilizes thenoyl trifluoroacetone (TTA) in benzene as solvent-C. Mahadevan, U. Aswathanarayana, V. V. S. S. Tilak, B. E. Vijayam and D. Purushottam, Department of Geology, Andhra University..... 

Even as a student of geology at Andhra UniversityWaltair, Vijayam and his fellow researchers were already carrying out research in the field. During 1954–1958, Vijayam had carried out research on geology in parts of Kurnool district. Vijayam's research articles began appearing in geological and other inter-disciplinary scientific journals for more than three decades and continue to be referred by the present generation of Geologists.

Vijayam stood witness to Christ and inspired many. During the Fifth National Convention of the Christian Businessmen's Committee in 1987 held in Hyderabad, he spoke on the theme You shall be witnesses unto me and shared dais with Archbishop Samineni ArulappaMember of parliament, Lok Sabha Marjorie Godfrey and Policeman G. Alfred, IPS. Vijayam also led honorary initiatives towards Christian missions by equipping the Laity not only with knowledge of the Gospel, but also a means of livelihood was recognised by Theologians, comprising the Missiologist, Roger HedlundSB, and Bishop Ezra Sargunam, ECI. During the 2000s, the Christian artist P. Solomon RajAELC made an Empirical research highlighting the new and indigenous missions, and Vijayam's effort falls in such line of indigenous missions to equip the grassroot Evangelists, which even the Old Testament Scholar, Victor PremasagarCSI appreciated such initiatives.

Life and background

Vijayam was born in 1933 in Giddaluru in erstwhile Madras Presidency during the colonial era to Bunyan Joseph, an Evangelist and grew up in rural India in the drought-prone Rayalaseema zone in southern India. The Church made an impact in the life of Vijayam as those were the days' of early Christians in the Telugu hinterland where the Catholic and the Protestant Missions had already set foot. Among the Protestant missions, the American Baptist Foreign Missionary Society, the London Missionary Society (LMS) and the Society for the Propagation of the Gospel (SPG) were the Christian missions at work in the Rayalaseema area. Vijayam grew up in a Christian household in mission compounds of the Churches as his father was a Priest, Canon and later Bishop. When Vijayam moved to Waltair in the 1950s, he also took part in the fellowship gatherings of the Canadian Baptist Ministries (Convention of Baptist Churches of Northern Circars).

Education and career

After initial studies in schools across Andhra Pradesh, wherever his father (Bunyan Joseph) was transferred, Vijayam moved to Madras Christian CollegeTambaram for a pre-University course (PUC). For undergraduate studies, he enrolled at Andhra UniversityWaltair, in 1953 and pursued graduate and postgraduate courses specialising in Geology. He was a direct student of Professor Calamur Mahadevan and U. Aswathanarayana and imbibed the subtle nuances for research which infused in him a flair for scientific research throughout his career in geological sciences. One of his companions during his study days at Waltair included the Theologian G. D. MelanchthonAELC. Vijayam was awarded with an M. Sc. in 1957.

Vijayam also pursued a Ph. D. programme during his early years at Osmania UniversitySecunderabad, on the topic Sedimentation in the upper proterozoic near Kurnool under the supervision of Prof. S. Balakrishna and was awarded a doctorate in the year 1965. He also spent time at Northwestern UniversityEvanston (United States) as a Postdoctoral researcher through the benevolence of Fulbright Program and also published a research article, Tectonic framework of sedimentation in the northwestern part of the San Andreqa fault zone at Park field, California on his return to India.


Vijayam joined the ranks of Geological Survey of India in 1961. He then moved to academics and joined Osmania UniversitySecunderabad, A State-run university, where he also pursued a Ph. D. programme. In 1965 and became a lecturer in the same university. Over the years, he rose to the ranks of a reader and professor and in 1984, he became head of the Department of Geology and chairperson of the board of studies.

Articles published

During the three decades, beginning with the 1960s, Vijayam researched together with his fellow geologists and brought out different aspects of the Earth's rich resources to the fore. He was also managing editor of Journal of Indian Academy of Geoscience during the 1970s.

Other initiatives

In addition to his academic pursuits, Vijayam was involved in founding entities as a means to bring in development in rural areas. Vijayam himself hailed from a rural family and his career pursuits brought him to an urban setting. In spite of it, he chose to better the lives of those in special circumstances. Towards this end, he drew talent from universities as a matter of service and also sought the partnership of United Nations Development Programme,[23]Government of India, and other funding agencies. In 1982, he also went to Bangla Desh to see the work of Social Entrepreneur and Nobel laureate Muhammad Yunus. In 2012, two sets of researchers working independent of each other had written about the work of Vijayam beyond the portals of learning.

University of Hyderabad researcher, Gadde Peda Rattaiah referred to the work of Vijayam in the context of partnerships with United Nations Development Programme and writes,

Professor Vijayam was a retired professor of Geology who worked, at the Department of Geology, Osmania University in Hyderabad. He founded MERIBA, PROGRESS, TENT, JVI, I-WILL agencies and his approach to poverty alleviation in rural India, was inspired by the Judeo-Christian values approach and was promoting attitudes of love, unity, mutual respect, self-help and collective action to overcome the hindrances to human deprivation, poverty and suffering.

Similarly, a group of Earth Scientists regarded the work of Vijayam in connecting Geology with development and write,

Community development initiatives without adequate geological input are potentially doomed to failure. For many years now, wonderful counterexamples have functioned under the guidance of distinguished geologist B. E. Vijayam in India. Vijayam’s NGO creations, including PROGRESS and TENT, integrate geological principles into almost every aspect of holistic rural development. Many of the village-level projects under TENT are planned to consider improvements in the context of a unified watershed. Water sources, sanitation, erosion, agriculture, land-use planning, and energy provision are all analyzed and managed as components of a larger, single geological system.


During 1978 Vijayam founded Mission to Encourage Rural Development in Backward Areas (MERIBA) as an entity to bring forth development in select areas of drought-prone Rayalaseema area of Andhra Pradesh amidst caste-ridden hegemony. The work of MERIBA was taken up in Kurnool district in the villages of Balapanuru, Kouluru, Neravada, Bhimaram and Yerraguntla. For organising Dalits through participatory management initiatives through Sarvodaya Sanghams, Vijayam's entity was also locked in horns with those oppressing the Dalits. There was indeed some resistance to the reformation that MERIBA ought to bring in and even the State executive was found to be in tandem with those oppressing the Dalits. It took judicial intervention to get the oppressors behind bars, but in no time they were freed and were ready to seek vengeance, but for the timely presence of Vijayam who sought reconciliation, an act which stunned the oppressors. Incidentally, Nagi Reddy, an advocate by profession, became MERIBA's first project director, and there was renewed activism in taking legal recourse in curbing atroticities on Dalits through SC/ST (Prevention of Atrocities) Act.


By 1982, Vijayam founded Peoples Research Organization for Grass-root Environmental Scientific Services (PROGRESS) as a platform to share the benefits of technological advancement with the rural poor. Select case studies and stories relating to the success of PROGRESS had been documented in 1994 by National Afforestation and Eco-Development Board and there also had been significant contribution by scientists working in PROGRESS to the environmental studies. In 1996, P. Sita Janki and K. Sumalini contributed a paper entitled Enhancement of seed germination in Amla (Emblica officinalis Gaertn.) by different growth regulator treatments[38] that appeared in the Journal for Tropical Forestry. A 2007 report of the University Grants Commission (UGC) listed PROGRESS among those NGOs  supported by it in advancing Rural development. PROGRESS was a member in the National Institute of HydrologyRoorkee.


The Theologians, F. Hrangkhuma and Sebastian Kim had recognised the efforts of Vijayam towards Tentmaking. At the same time, Roger Hedlund had acknowledged Vijayam's efforts towards founding TENT in equipping individuals with means of livelihood as well as basic theological principles. It was in 1985 that Vijayam founded Training in Evangelism Needs and Technology (TENT), intertwining technology with theology for ministerial advancement, which the notable Entomologist P. Judson has also been associated.

Nag's work focused on semiconductors and it helped in widening our understanding of the electrical transport phenomena in those high electrical resistant solids. During his early years at Calcutta University, he led a group of students who were engaged in the studies on microwave measurements of semiconductor properties and did advanced research on Gunn effect and microwave radiation. He demonstrated the temperature independence of Two-dimensional electron gas and its alloy scattering limited mobility which was a first time discovery. His studies revealed the non-parabolic nature of electron energy dispersion in narrow quantum wells and this modified the theory of interface roughness scattering limited mobility for Quantum Wells with finite barrier height and Well width. Liquid phase Epitaxy Semiconducting III–V compounds, acousto-electric effect and free carrier absorption, Gini ratio and Si coefficient related to hot-electron galvanomagnetic transport were some of the other areas of his research. He contributed to the development of electron transport theory related to semiconductors and developed a Monte Carlo method for the computation of coefficients related to velocity correlation, diffusion and noise parameters. His body of work is reported to have relevance to the fields of microwave communications and radar, especially in the development of microwave semiconductor devices. His studies have been documented by way of a number of articles and the article repository of the Indian Academy of Sciences has listed 190 of them. He authored three monographs, Theory of electrical transport in semiconductors, Physics of Quantum Well Devices and Electron Transport in Compound Semiconductors of which the last mentioned is reported to be a significant reference text for researchers. He also contributed chapters to books published by others and his work has drawn citations in a number of books.

Awards and honors

Nag, a founder fellow of the Indian National Academy of Engineering, received the J. C. Bose Memorial Prize of the British Institution of Radio Engineers in 1964. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 1974. He was selected for the Jawaharlal Nehru Fellowship in 1975 and the Indian National Science Academy elected him as a fellow in 1978; the academy would honor him again in 1993 with the INSA Prize for Materials Science. He became an elected fellow of the Indian Academy of Sciences. The department of radio physics and electronics of the University of Calcutta instituted an annual conference, International Conference on Computers and devices for Communication (CODEC), in his honor in 1998, a year after Nag retired from academic service

(b. Baltimore County, Maryland, 9 November 1731; d. Baltimore County, 9 October 1806)

observational astronomy, ephemerides, almanacs.

A tobacco farmer, and amateur astronomer, Benjamin Banneker was an inspiration for his mathematical achievements. He is frequently described as the first African American man of science.

Early Life. Banneker was born free in Baltimore County, Maryland, on 9 November 1731. He was the son of a freed slave from Guinea named Robert and of Mary Banneky, daughter of a formerly indentured English servant named Molly Welsh and her husband, Bannka, a slave whom she freed and who claimed to be the son of a Gold Coast tribal chief.

Banneker’s early years were spent with his family, including three sisters, growing tobacco on his parents’ 100-acre farm near the banks of the Patapsco River. In his early years he had been trained to read and write by his grandmother by means of a Bible she had purchased from England, but his only formal schooling was attendance for a week or two in a nearby Quaker one-room schoolhouse. Benjamin became a voracious reader, borrowing books from wherever he could, and developed considerable skill in mathematics. He enjoyed devising mathematical puzzles and solving those brought to him by others. At about the age of twenty-one he constructed a striking wall clock, without ever having seen one. It is said that it was based on his recollections of the mechanism of a pocket watch. Apparently, he visualized it as a mathematical puzzle, relating the numerous toothed wheels and gears, carving each carefully from seasoned hardwood with a pocket knife. For a bell, he utilized either part of a glass bottle or metal container. The timepiece appears to have been the first clock in the region and brought those who had heard about it to his cabin to observe it and listen to it strike. The clock continued to function successfully for more than fifty years, until his death.

Inheriting the family farm at his father’s death, Banneker lived with his mother until her demise. Then living alone, he continued to grow and sell tobacco until about the age of fifty-nine, when rheumatism forced him to retire. His farm made him virtually self-sufficient, with a productive vegetable garden, thriving fruit orchards, and several hives of bees that he maintained. Banneker and his family had been among the first clients of the newly established Ellicott Store, in nearby Ellicott’s Lower Mills, and during his leisure he continued to visit it frequently, purchasing small items he required, perusing the wealth of imported merchandise, occasionally purchasing an inexpensive book for his own small library. Most of all he enjoyed the opportunity to read newspapers from other cities that the store sold and that provided him with a link to the outer world.

Now, with the freedom of retirement from work, Banneker turned with new vigor to his astronomical studies, often whiling away the hours until dawn scanning the night skies with his telescope and recording notations for an ephemeris for an almanac he was compiling for the following year.

Work in Observational Astronomy. It was just at this time that fate sought him out for an important role to play in the nation’s history. The surveyor Andrew Ellicott had recently been appointed by President George Washington to produce a survey of selected lands on which to establish a national capital. Ellicott urgently required an assistant with some knowledge of astronomy to work in the field observation tent during the night hours. He traveled to Ellicott’s Lower Mills hoping to hire his cousin George Ellicott, Banneker’s neighbor, who was an amateur astronomer. However, his cousin, being unable to leave his own work, instead recommended Banneker, whom he felt had become sufficiently informed on the subject to fulfill the position. Banneker was hired and, overwhelmed by the opportunity, he traveled together with Andrew Ellicott to the site that was to become the national capital, arriving early in the new year of 1791.

Banneker worked in the observatory tent for more than four months, from the beginning of February until the end of April 1791. It was grueling work, for he was forced to spend the long hours of the night lying on his back in order to use an instrument called a zenith sector. His assignment was to observe through the instrument’s telescope as stars transited over the zenith, noting the exact moment of each star’s transit and recording it for Ellicott’s use when he arrived the next morning.

It was extremely tiring work for a man of Banneker’s advanced years, but despite the discomfort, he derived considerable pleasure and pride from the knowledge that he was contributing to such an important project. Also, after taking a nap during the early daylight hours, Banneker had the privilege of using Ellicott’s astronomical textbooks, which were maintained in the observatory tent. This enabled him to complete the ephemeris he was compiling for an almanac for the following year, 1792. For his participation on the survey, including travel, Banneker was paid a total of $60.

Correspondence with Jefferson. Soon after returning home, Banneker sent a handwritten copy of his completed ephemeris to Secretary of State Thomas Jefferson because, as he wrote, Jefferson was considered to be “measurably friendly and well disposed towards us,” referring to the African American race, “who have long laboured under the abuse and censure of the world. … And have long been looked upon with an eye of contempt, and … long have been considered rather as brutish than human, and scarcely able of mental endowments (1792).”

Submitting his calculations as evidence to the contrary, Banneker urged Jefferson to work toward bringing an end to slavery. Jefferson answered promptly:

No body wishes more than I do to see such proofs as you exhibit, that nature has given our black brethren, talents equal to those of other colors of men, and that the appearance of a want of them is owed merely to the degraded condition of their existence, both in Africa & in America. … No body wishes more ardently to see a good system commenced for raising the condition of both their body & mind to what it ought to be, as fast as the imbecility of their present existence, and other circumstances which cannot be neglected, will admit. (Payne, 1862, pp. 168–171)

Jefferson was so impressed with Banneker’s calculations that he sent a copy to the Marquis de Condorcet, secretary of the French Academy of Sciences in Paris, with an enthusiastic cover letter. No reply was forthcoming from Condorcet, however, because at just the time of the arrival of Jefferson’s letter, the French diplomat had been forced to go into hiding for opposing the monarchy and for having supported a republican form of government. During the following year, the two letters, the one from Banneker to Jefferson and the statesman’s reply, were published in the United States in a widely distributed pamphlet and in at least one periodical.

Publication of the Almanac. James McHenry, a senator from Maryland, had been so impressed with Banneker’s almanac manuscript that he wrote an endorsement for it that was published together with the almanac by the Baltimore printer Goddard & Angell. The almanac bore the title Benjamin Banneker’s Pennsylvania, Delaware, Maryland, and Virginia Almanack and Ephemeris for the Year of Our Lord 1792. In addition to its sales in Baltimore, the almanac was made available also by printers in Alexandria, Virginia, and in Philadelphia. It proved an immediate success, and Banneker’s lifestyle soon changed somewhat, as he became acknowledged by neighbors and occasionally by others visiting the region.

During the next five years, Banneker continued to calculate ephemerides, which he sold and which were published in almanacs bearing his name in the title. Promoted by the abolitionist societies of both Pennsylvania and Maryland, Banneker’s almanacs were published by several printers and sold widely in the United States and also in England. Twenty-eight separate editions of his almanacs are known to have been published.

Generally, in the production of an almanac, the astronomer provided only the ephemeris, and the remaining content was selected and furnished by the printer, who often selected random prose and poetry taken from the published press or journals. Frequently included were useful tables of weights and measures, coinages, interest rates and scales of depreciation, measurements of roads, and distances of cities from the place of publication, a calendar of meetings of courts of law holding sessions where the almanacs would be sold, and so forth.

The remainder of the pages of these inexpensive and poorly printed pamphlets generally were filled with moral elevating scriptural quotations, proverbs, allegorical stories, and puritanical essays. By the beginning of the eighteenth century, however, the almanac’s content changed distinctly in tone from its earlier religious bias to one of more practical considerations, with emphasis on education and literary and historical content. As a consequence, in time the almanac became more entertaining, with homely wisdom cast in contemporary language. By the end of the eighteenth century, the publication had become the most common printed item in the American republic, printed in every state, each vying with others in developing a new marketable item. In the period that Banneker was undertaking the preparation of an ephemeris, the century was drawing to a close and once more the almanac content was undergoing a change, with new emphasis on local causes and national events.

In a period when clocks and watches were luxuries and common timepieces consisted primarily of time glasses and sundials, information about the times of sunrise, noon, and sunset were of considerable importance to the prospective purchaser, as well as the phases of the moon, eclipses, and conjunction. Among the most desirable and useful features of Banneker’s almanacs proved to be a tide table for the Chesapeake Bay region, which made his almanacs particularly desirable for river pilots, fishermen, and others living near and making their living on the water. It listed times for high water or high tide at Cape Charles, Point Lookout, Annapolis, and Baltimore. Why Banneker’s competitors ignored this feature is hard to understand, because it was simple enough to calculate the high tide at Annapolis, for instance, which was two hours later than at Point Lookout, while at Baltimore and Head-of-the-Bay the high tide was five hours later than at Point Lookout. The tide table was simplified considerably in Banneker’s almanacs for the years 1795 and 1796, which provided data for determining tides in ports as distant north as Halifax and Boston. This feature was titled “Rule to find the Time of High Water in the following Places” and consisted simply of an additive for each of the places listed, to be combined with the day of the Moon’s age.

It was Banneker himself and not his printer who compiled the tide tables for his almanacs. It was a simple matter to acquire the data, and no mathematical

achievement was involved. The changing of the tides had been associated with the motion of the Moon for centuries. Once the time of the highest or spring tide was known at a particular point at the age of the full or new moon, it was a simple matter to derive a table for each day of the month at the same place. Banneker applied the standard daily retardation of forty-eight minutes, or four-fifths of an hour. This determination of the highest tide waters or spring tides on the days of the full or new moon was known as “the establishment of the port” and generally was marked on the charts for the port in question.

From data in his published almanacs, it is evident that Banneker made his observations from a point of latitude 39°30’ north and a longitude of 4 hours, 59 minutes west. In addition to recording in his manuscript astronomical journal the ephemerides for each of the years for which he calculated them, Banneker also included miscellaneous exercises in mathematics and astronomy.

In the pages of his manuscript astronomical journal as well as in his commonplace book, Banneker occasionally recorded miscellaneous items about unusual atmospheric phenomena he had observed. Typical of these random notes was an entry on the very first page of the journal, under the date of 23 December 1790. He noted, “About 3 o’clock A.M. I heard a Sound and felt the Shock like heavy thunder I went out but could not observe any Cloud above the Horizon. I therefore Conclude it must be a great Earth Quake in some part of the Globe.” Another item, recorded on 4 May 1792, described how “In a Squall from the N.W. I observed the Lower regions of the Clouds to move Swiftly before the wind, and the upper region Slowly against it.”

Even in his later years the weather continued to preoccupy him. On 2 February 1803, he noted,

in the morning part of the day, there arose a very dark Cloud, followed by Snow and haile a flash of lightning and loud thunder crack, and then the Storm abated untill after noon, when another cloud arose the Same point, viz, Northwest with a beautiful Shower of Snow but what beautyfyed the Snow was the brightness of the Sun, which was near Setting at the time.

A comparison of the contents of Banneker’s published ephemerides made with those calculated and published by his contemporaries Ellicott, William Waring, and Mary Katherine Goddard, has revealed that Banneker’s calculations consistently reflected an overall high degree of comparative accuracy. An error analysis of the astronomical data in Banneker’s almanacs revealed that his data compared very favorably with that published by his contemporaries. There was no significant difference between Banneker’s star data and that published by the two contemporary almanac makers. Although Banneker’s planetary data may have appeared to be somewhat less accurate than that of Ellicott or Goddard, it was still quite usable by the ordinary purchaser of the almanac. Considering that the length and complexity of the calculations involved in determining the rising and setting of certain stars and planets, and realizing that this was only a small segment of the mathematics required for one year’s almanac, one can have only the greatest respect for this self-taught man of science.

Although Banneker continued to calculate ephemerides every year through the year 1802, those after 1797 remained unpublished, but were carefully recorded in his manuscript journal and commonplace book, which survive as unique records of an eighteenth-century almanac maker.

Character. Banneker espoused no particular religion, but as an early biographer noted, “His life was one of constant worship in the great temples of nature and science.” (Allen, 1921) As places of worship in his vicinity grew in number, Banneker visited each of them, but gave preference to the meetings of the Society of Friends, where “he presented a most dignified aspect as he leaned in quiet contemplation on a long staff, which he always carried after passing his seventieth year. And he worshipped, leaning on the top of his staff.” (Allen, 1921)

A description of Banneker was provided by Martha Tyson, daughter of George Ellicott, who had seen him when she was a young woman. “The countenance of Banneker,” she wrote,

had a most benign and thoughtful expression. A fine head of white hair surmounted his unusually broad and ample forehead, whilst the lower part of his face was slender and sloping towards the chin. His figure was perfectly erect, showing no inclination to stoop as he advanced in years. His rainment was always scrupulously neat; that for summer wear, being of unbleached linen, was beautifully washed and ironed by his sisters. … In cold weather he dressed in light colored cloth, a fine drab broadcloth constituting his attire when he designed appearing in his best style.

No known portrait of Banneker exists. Lacking such, an image frequently used is a woodcut portrait bust of a young black man, imaginary and not based on life, wearing the typical Quaker garb of the period. Purported to be of Banneker, this image illustrated the cover of a 1797 edition of one of his almanacs. The most accurate representation known may be found on a modern mural painting by the late William H. Smith of the survey of the federal territory. It hangs in the Maryland House on the John F. Kennedy Highway in Aberdeen, Maryland. In 1980 the U.S. Postal Service issued a commemorative stamp honoring Banneker based on imagined features.

On 9 October 1806, during a nap following his usual morning walk, Banneker quietly died in his sleep, just one month short of his seventy-fifth birthday. In accordance with instructions he had left, immediately following his death all the items that had been borrowed from his neighbor George Ellicott, including the worktable, instruments, and books, had been returned to him by Banneker’s nephew. Included also was Banneker’s astronomical journal.

Banneker was buried two days later, on Tuesday, 11 October, in the family burial ground within sight of his house, a few yards away. During the services, as his body was being lowered into his grave, the mourners were startled as they looked up to see his house, a wooden building, suddenly burst into flame. Before help could be summoned, the entire structure burned to the ground. All its contents were totally destroyed, including Banneker’s clothing and other personal possessions, a few bits of furniture, a sparse collection of books and printed copies of his almanacs, as well as the fabled well-worn striking clock. The only item known to have escaped destruction was his quarto Bible, which had been removed from his house after his death and before the funeral, probably by one of his sisters. The cause of the conflagration was never determined.

Banneker’s death did not pass totally unnoticed. An obituary announcement appeared in the Federal Gazette on 28 October 1806, almost three weeks after his death. It provided a description of Banneker’s way of life and concluded, “Mr. Banneker is a prominent instance to prove that a descendant of Africa is susceptible of as great mental improvement and deep knowledge into the mysteries of nature as that of any other nation.”

Died October 9, 1806 (Baltimore County, Maryland)

Mathematician, astronomer

Benjamin Banneker was an accomplished self-taught mathematician and astronomer. He is considered America's first black scientist. Banneker calculated the daily position of celestial bodies (visible stars and planets in the night sky) and printed this information in charts, which he published in yearly almanacs. His almanacs also featured calendars, times of sunrise and sunset, phases of the moon, and other useful information. Banneker's almanacs for the years 1792 to 1797 were widely published. They brought international attention to Banneker, in large part because it was an unparalleled achievement for a black American to publish at all at that time in history.

"I suppose it is a truth too well attested to you, to need a proof here, that we are a race of beings who have long laboured under the abuse and censure of the world."

Benjamin Banneker, in a letter to Thomas Jefferson

In 1791, Banneker assisted in the land survey of the future site of Washington, D.C. Perhaps Banneker's greatest accomplishment was his plea for civil rights in his correspondence with then-U.S. secretary of state Thomas Jefferson (1743–1826; see entry in volume 1). Banneker called for the abolition (prohibition) of slavery and challenged Jefferson to work for the ideals he had promoted for all citizens in the 1776 Declaration of Independence. The Declaration of Independence was the historic document announcing that the American colonies had rejected British rule and were forming a new nation, the United States of America.
The New World

Benjamin Banneker was a free black (non-slave) born in the British colony of Maryland in 1731. At the time, thirteen colonies made up the new land of America. Banneker's birthplace was on the family farm near the Patapsco River, in the area that eventually became known as Oella, Maryland.

Banneker's grandmother was a white woman named Molly Welsh. Accused of a crime in England, she was pardoned on the condition that she leave the country and settle in the American colonies. She arrived in Maryland in 1683 aboard a ship filled with other laborers headed for the New World. After working to pay off the money she owed for her transportation to America, Welsh established a small tobacco farm on the Patapsco River. Tobacco was an important crop in Maryland, where the weather and soil provided perfect growing conditions. Because she needed help on the farm, Welsh purchased two slaves who had just arrived from Africa and put them to work. She married one of them, a man named Banna Ka. People called him Bannaky, although over time the spelling was altered to Banneky. The couple had four children together.

In 1730, the Bannekys' eldest daughter, Mary, married a freed black slave named Robert, and he took her last name, Banneky, as his own. Benjamin was the first child born to Robert and Mary Banneky. (The family name was later changed to Banneker.) He was soon joined by three sisters. The entire family lived in Molly Welsh's cabin, and all of them did their part to make the farm successful. Few black families owned farms at that time, because most blacks were slaves, but the Bannekys made a good living raising tobacco. Grandmother Molly taught Benjamin and his sisters to read and write by having them study the Bible she had brought with her from England, the only book the family owned.

A Land For Life

By 1737, Robert and Mary Banneky had saved enough money to buy an additional 100 acres on a tract of land called Stout. Although Benjamin was only six years old, his father added the boy's name to the deed of ownership. The land was located near the Chesapeake Bay. The Bannekys built a log cabin there, and Benjamin would live in that cabin for the rest of his life.

Benjamin enjoyed learning and attended a one-room country school for several years during the winter months, when work on the farm slowed down. For the rest of the year, he taught himself literature, history, and religion with books he borrowed. He was especially gifted in mathematics and showed a talent for creating and solving mathematical puzzles. It was around this time that the spelling of Benjamin's family name changed to Banneker.
On Time

The demands of the farm soon ended young Banneker's formal education, but his love of learning continued. Along with mathematics, he was particularly interested in studying machines. When Banneker was twenty-one years old, he was given a pocket watch to examine. Always interested in a mathematical challenge, he took the watch apart and drew pictures of what he saw. He then calculated the ratio of the gears and wheels in order to build a clock for himself. He carved each piece from wood with a pocketknife and, with a few necessary metal pieces, built a clock that kept perfect time for the rest of his life.

The clock was a rare sight in rural eighteenth-century America and became the subject of considerable interest throughout the region (see box). Banneker was soon quite famous in his community, as word spread rapidly about his fascinating timepiece. People who lived in the county may not have heard of Benjamin Banneker the farmer, but they soon began talking about Benjamin Banneker the clock maker. They came from all over the valley to visit his farmhouse and see the clock with the brass bell that chimed on the hour.

In 1763, Banneker purchased his first book, a Bible, in which he recorded the date of his own birth as well as the date of his father's death, July 10, 1759. His sisters married and moved to their own homes nearby, while Banneker and his mother continued to work the farm until her death in 1775. Banneker bought a flute and a violin and learned to play them by practicing after his regular work-day was over. Occasionally, neighbors or relatives would stop by to enjoy the music he played each evening on his front porch.

Astronomy's Pull

In 1771, Banneker turned forty. That same year, he had new neighbors—the Ellicott family—who purchased large tracts of land next to his farm. The Ellicotts built flour mills, sawmills, and a general store, which together invigorated the area's economy. Once the flour mills opened, local farmers were able to produce crops other than tobacco for a profit.

Banneker's relationship with the Ellicotts began with a contract to supply food for the many workers they employed, but he soon became friends with the family. Even though it was less expensive to buy slaves than to hire workers at the time, the Ellicotts chose not to own slaves. They belonged to a Christian church called the Society of Friends, whose members were called Quakers. Quakers opposed slavery and believed that all people should be treated with equal respect.

Keeping Time

Clocks were rarely seen in rural America in the eighteenth century, because few people needed to keep precise track of time. Most people told time by watching the position of the sun in the sky. Farmers in particular began their workday when the sun came up, ate lunch when the sun was high overhead, and ended the workday when the sun went down. In a society where most people were farmers, the position of the sun was far more important than the position of hour and minute hands on a clock.

Rural America tended to view timepieces as a novelty. Church bells rang on the hour and were often used to announce celebrations or emergencies. However, most people lived on farms and plantations, too far from settlements to hear them ringing. The boom of a cannon was substituted for the ringing of a bell when time came to announce important events such as the arrival of a supply ship at the docks in tidewater Maryland.

Banneker continued working his farm and devoted more acres to grain that would be sold to the Ellicotts. In 1775, the American Revolution (1775–83) began. Free blacks like Banneker were not required to join the army, and none of the battles took place within Maryland's borders; therefore, Banneker's life remained much the same as it had always been. By the late 1780s, Banneker had developed a special friendship with George Ellicott (1760–1832), largely based on their common interest in the sciences. Ellicott, nearly thirty years younger than Banneker, was a skilled surveyor and astronomer. He loaned Banneker a telescope, several astronomy books, and a sturdy wooden table on which to use them. Banneker studied the books and the skies for hours each night. He faithfully recorded the movements of the stars and planets he observed. Banneker taught himself so well that he was able to predict the solar eclipse of April 14, 1789, which even well-known scientists had not expected.

Banneker spent most of 1789 observing the sky every night in order to calculate information for a 1790 almanac he hoped to produce. Armed with all the necessary astronomical calculations, Banneker contacted several different publishing houses, but he was unable to get his work published. Members of abolitionist societies (organizations opposed to slavery) in Maryland and Pennsylvania heard of his accomplishments and rallied to try to help Banneker find a publisher. They knew that if an almanac authored by a free black was published, it would serve as valuable proof of the intellectual abilities of all blacks; this, in turn, would help them in the fight against slavery. Their efforts to find a publisher came too late for the 1791 almanac, so Banneker began work on calculations for 1792.

Building The Nation's Capital

Although America had finally won its independence in 1783, the new country did not yet have a capital city. In 1790, U.S. president George Washington (1732–1799; served 1789–97; see entry in volume 2) appointed a famous French architect named Pierre-Charles L'Enfant (1754–1825; see entry in volume 2) to design a new city that would be the nation's capital. It was to be located on the Potomac River (which separated parts of Maryland and Virginia). Washington also appointed a land surveyor, Major Andrew Ellicott (1754–1820), who was George Ellicott's cousin. Major Ellicott needed an assistant to make astronomical calculations for the survey; he naturally recommended Banneker. George Ellicott's wife, Elizabeth, helped Benjamin pick out new clothes for the trip, anticipating that he would meet many important people while working on the survey.

In January 1791, Banneker left his farm in the care of his sisters and joined the team assigned to build the capital of the United States. It was his first trip away from his cabin in Maryland. By the end of April, his work completed, Banneker returned to his farm and resumed his calculations for a 1792 almanac.

A Plea For Freedom

With the support of George Ellicott and the Pennsylvania and Maryland abolition societies that had previously shown an interest in his work, Banneker's 1792 almanac was published in late 1791. A few months before publication, Banneker sent a manuscript copy to Secretary of State Thomas Jefferson; Banneker enclosed a letter urging the abolition of slavery. Jefferson wrote back quickly, thanking him for the almanac. In his response, Jefferson expressed a desire "for raising the condition" of slaves and stated that Banneker's book could prove the intellect of blacks. Otherwise, he largely avoided the issue of freedom for blacks in his brief letter.

The correspondence between Banneker and Jefferson was published as a pamphlet and distributed at the same time that the almanac appeared. The almanac's first edition came out in December 1791. It sold out immediately, so a second edition was required. The following year, Banneker's almanac included the letter he had written to Jefferson and Jefferson's reply. In 1795, the almanac added a new feature, a portrait of Banneker on the cover. Banneker published an almanac every year until 1797, when sales declined. Competition had increased from publishers of other almanacs (see box). In addition, interest in the abolition movement, which had promoted Banneker's almanac as proof of black Americans' potential, was dwindling. Banneker continued with his annual calculations until 1804, but none of them were ever published. He simply continued the practice for his own enjoyment.

The financial success of his early almanacs allowed Banneker to spend less time farming. He sold most of his land and pursued a variety of interests, although his health was declining. He continued to live in his own home until his death on October 9, 1806, just one month short of his seventy-fifth birthday. Prior to Banneker's funeral, at Banneker's request, a nephew had collected all the borrowed texts and instruments from his uncle's cabin in order to return them to George Ellicott. All of Banneker's other possessions were destroyed when his cabin caught fire; this occurred at the same hour that his relatives were burying him in the family graveyard. Everything was lost, including his clock and most of his personal papers. Benjamin Banneker did not live to see the end of slavery, which would not occur for nearly sixty years. However, Banneker's accomplishments helped shape America by providing inspiration for others in the quest for freedom.

Almanac: An Important Reference Book

In colonial times, most people owned an almanac. It contained a yearly calendar that determined when holy days and festivals were celebrated. It also told people when they could expect an eclipse (when Earth blocks the Sun's light on the Moon or the Moon blocks the Sun's light on Earth). If a person did not own a clock, an almanac could report on the time of day. It listed the times of sunrise and sunset. Farmers used their almanacs to gauge when to plant their crops and to find predictions about weather changes from season to season. Sailors referred to the almanac's charts of the stars to determine their position on the seas.

Many publishers produced almanacs each year, but perhaps the most popular ever produced was Poor Richard's Almanac, created by statesman and scientist Benjamin Franklin (1706–1790; see entry in volume 1). First published in 1732, it became the model for other almanacs to follow.

Research Interest

The main aim of our laboratory is to understand the mystery of glycosylation of biomolecules with special emphasis on the role of sialoglycoconjugates in different disease models and its potential applications in disease management, its specificity and recognition in immune responses mainly in the field of cancer biology/tumor immunology and host-pathogen interactions dealing with visceral leishmaniasis (VL) and Pseudomonas aeruginosa (PA). We have analyzed childhood acute lymphoblastic leukemia (ALL), VL and PA-associated biomolecules by exploring the diversity of sialylation with a common set of questions through proteomic and glycobiological aspects.

Additionally, another important goal of our laboratory is to deliver low cost affordable healthcare to all using India’s vast resources of medicinal plants. Currently we had put lots of effort towards chemotherapeutic advancement in cancer since 2008. My group has identified a non-toxic herbal molecule alone/or extract/or in-combination with existing-known drugs showing great potential against an array of cancer cell lines/ cancer stem cells both in vitro and in vivo and even in hypoxic condition.

Dorairajan Balasubramanian, popularly known as Professor Balu, is an Indian biophysical chemist and ocular biochemist. He is a former President of Indian Academy of Sciences and a Director of Research at the Prof. Brien Holden Eye Research Centre of L. V. Prasad Eye Institute, Hyderabad. A recipient of the National Order of Merit (France), Balasubramanian was honored by the Government of India, in 2002, with the fourth highest Indian civilian award of Padma Shri


Dorairajan Balasubramanian was born on 28 August 1939 in the South Indian state of Tamil Nadu. He graduated in Chemistry (BSc) from Madras University in 1957 and secured his master's degree (MSc) in Chemistry with first rank in 1959 from BITS, Pilani. He moved to the United States in 1960 for researching for his doctoral studies and completed it in 1965 to obtain PhD in biophysical chemistry from Columbia University He continued in the United States for his post doctoral research as a Jane Coffin Childs Fund Fellow at the University of Minnesota Medical School till 1966.

Balasubramanian returned to India in 1966 and joined the Indian Institute of Technology, Kanpur as a lecturer where he rose in ranks over the years to become an assistant professor and a professor. In 1977, he was appointed as the professor and dean of the School of Chemistry at the University of Hyderabad where he worked till 1982 when he took up the post of the deputy director of the Centre for Cellular and Molecular Biology. He retired from the institution as its director in 1998 and moved to L. V. Prasad Eye Institute where he is the director of research of Prof. Brien Holden Eye Research Centre. He also serves as the visiting professor at the University of New South Wales, Sydney and as the adjunct professor of Birla Institute of Technology and Science, Pilani, India.

Balasubramanian is married to Shakti who is associated with E TV as a producer and the couple has two daughters. The elder daughter, Katyayani is a research analyst and the younger one, Akhila works as a public health professional. The family lives in Hyderabad.


Balasubramanian is a visiting scientist at the National Eye InstituteBethesda and is a senior Fellow of ophthalmology at the University of Melbourne. He is the chairman of the Task Force on Stem Cell Research set up by the Department of Biotechnology of the Government of India. He is a former president of the Indian Academy of Sciences (2007-2010) and is the incumbent the chairman of the Biotechnology Advisory Council of the Government of Andhra Pradesh. A former secretary general of The World Academy of Sciences, he has served as the project coordinator of Translational Centre in Eye Diseases of Champalimaud Foundation (C-TRACER) and the Affordable Healthcare Project of the Wellcome Trust for finding solutions for the use of scaffolds for cultivating stem cells. He is a former member of the International Human Rights Network of Academies and Scholarly Societies, the International Basic Sciences Panel of UNESCO and the International Chapter Affiliate Committee of the Association for Research in Vision and Ophthalmology (ARVO), United States. He has also served as an editorial board member of several international journals.

Cataract in human eye
Ginko tree

Balasubramanian started his research activities in 1965 focusing on the structure and functions of proteins and polypeptides and worked on the thermodynamic analysis of their stability. The focus of his research changed in 1984/85 when he started to work on ocular science and concentrated on crystallins of eye lens and their function as an agent in keeping the lens transparent His research revealed how cataract is caused when crystallins are damaged photochemically, thereby leading to diminished lenticular transparency. He argued that the oxidative stress on the lens induces covalent chemical changes in the constituent molecules and these changes lead to cataract.He researched further on the subject to find out that, by supplementing antioxidants and cytoprotective substances, the progression of cataract can be slowed down. These findings are known to have introduced a prophylactic approach to addressing the issue of cataract, which is reported to be the causal factor for 47.9 percent of the blindness in the world. Further, he attempted to identify the cataractostatic agents and proposed the benefits of tea polyphenolsGinko Biloba and Withania somnifera extracts. These substances contained antioxidants and cytoprotective compounds which slow down the progression of oxidative cataract and this was verified during experiments in animals.
Advanced vision loss from Glaucoma.

After the turn of the century, Balasubramanian and his colleagues started working on inherited eye diseases and their molecular genetics. The group carried out research on diseases such as congenital glaucoma with a sampling set of over 400 families and this has helped in revealing 15 mutations in the gene CYP1B1, with mutation R368H being the most common one. The research has also recorded the genotype-phenotype correlations and the structural changes occur in mutated protein and these findings have assisted in clinical prediction of the disease and in early therapeutic intervention to avert blindness.

Balasubramanian is now working on stem cell biology and its use in restoring lost vision. He and his group have been successful in isolating the adult stem cells found in the limbus, around the cornea, and culturing them on human amniotic membrane. These cultured stem cells were, later, used to produce corneal epithelia that can be stitched on to human eye. Clinical tests on 200 patients who lost eyesight due to chemical or fire burns returned significantly good results with vision restoration to 20/20 levels, with or without subsequent corneal grafts or transplantation. These tests are reported to be the largest successful human trial of adult stem cell therapy in the world.

Balasubramanian has published 6 books of which two books, one on chemistry and the other in biotechnology, are prescribed text books for academic studies. He is credited with over 450 articles, published in peer reviewed national and international journals and Microsoft Academic Search, an online repository of scientific articles, has listed 52 of them. He has presented more than 170 scientific papers and has contributed in popularizing science by writing columns in leading newspapers such as The Hindu and The Times of India since 1980. On the academic front, he has assisted 16 doctoral students in their PhD studies. His efforts are also reported behind the establishment of a vaccine unit at the Centre for Cellular and Molecular Biology and in designing a quality improvement program for the Sericulture Laboratory of the state government.

दादाजी खोब्रागड़े

कृषिरत्न, कृषिभूषण

विश्वप्रसिद्ध एचएमटी धान (चावल) समेत अन्य 8 से अधिक धान की नई प्रजातियों के संशोधक च्रदपुर नांदेड़ निवासी 80 वर्षीय कृषिरत्न, कृषिभूषण दादाजी खोब्रागड़े पैरालिसिस के कारण दुःखद निधन हुआ। पिछले कुछ महिनों से पैरालिसिस के कारण उनपर इलाज चल रहा था. स्‍थानीय नीजि अस्‍पताल 'सर्च' में वे में भरती थे. साल 2015 में उन्हें अर्धागवायु अर्थात पैरालिसिस का अटैक आया था.

आज अगर आप 'बिग बाजार' या 'डी मार्ट' जैसे बीग ब्रांड ग्रोसरी माल में जाते है तो राईस सेक्‍शन में आपको एचएमटी राईस की कई वरायटी मिलेंगी. उन्‍होंने विकसित की हुई एचएमटी धान ने भारत में चावल की फसल में क्रांतिकारी बदलाव लाया है. मध्‍यभारत के एक लाख हेक्‍टर से ज्‍यादा जमीनपर यह एचएमटी धान उगाया जाता है.

चंद्रपुर जिले की नागभीड़ तहसील के गांव नांदेड़ निवासी अनुसूचित जाति में जन्‍में कृषि मजदूर दादाजी रामाजी खोब्रागड़े सिर्फ 3 री कक्षा तक की शिक्षा अर्जित कर पाए थे। थोड़ी-सी जमीन में परंपरागत पद्धति से धान की फसल लेकर और बचे हुए समय में मजदूरी कर उनका परिवार गुजारा करता था। कुछ नया करने की चाह में दादाजी हर चीज का गहनता से अध्ययन करते थे। जिससे उनकी निरीक्षण शक्ति बढ़ी।

परंपरागत धान प्रजाति से अलग धान प्रजाति का उत्पादन करने का विचार मन में आते ही उन्होंने वर्ष 1983 को पटेल-3 नामक धान प्रजाति की फसल बोयी। उसमें उन्हें तीन अलग-अलग किस्म के धान के बीज मिले।

उन्होंने तीन वर्ष में कड़ी मेहनत कर धान की नई प्रजातियां तैयार कीं। उस वक्त इन प्रजातियों के धान का नाम रखे बिना ही इन्हें बाजार में बिक्री के लिए लाया गया। व्यापारियों ने जब उनसे इस धान के नाम पूछे तो उन्होंने इसका नाम उस समय की प्रसिद्ध घड़ी HMT बता दिया। तब से सामने आई HMT चावल की नई प्रजाति।

इससे दादाजी खोब्रागड़े HMT चावल के जनक के रूप में सुप्रसिद्ध हुए।

कृषि क्षेत्र में दिए गए योगदान के लिए महाराष्‍ट्र राज्य सरकार ने 2006 में कृषि क्षेत्र के सर्वोच्च पुरस्कार कृषि रत्न से उन्हें सम्मानित किया।

5 जनवरी 2005 को अहमदाबाद में तत्कालीन राष्ट्रपति डा. एपीजे अब्दुल कलाम के हाथों उनका अनुसंधान के लिए सम्मानित किया गया।

2010 में अंतरराष्ट्रीय फोब्र्स मैग्जीन ने विश्व के सर्वोत्तम ग्रामीण उद्योजकों की सूची में स्थान देकर उन्हें सम्मानित किया था।

वर्ष 1990 से लेकर 2015 तक वे अनेक पुरस्कारों से नवाजे गए।

भारत एवं विश्‍व की तमाम अखबारों की सुर्खियों में रहें दादाजी भारत सरकार के विज्ञान एवं प्रौद्योगिकी विभाग क स्‍वायत्‍त संस्‍थान राष्‍ट्रीय नवप्रवर्तन प्रतिष्‍ठान के राष्‍ट्रीय अन्‍वेषकों की सूचि में गर्व से शामिल हैं.

साल 2015 में उन्हें अर्धागवायु अर्थात पैरालिसिस का अटैक आया और उनका काम वहीं रुक गया।

किसानों एवं युवा कृषि संशोधकों के ल‍िए दादाजी खोब्रागड़े आदर्श है एवं प्रेरणास्‍थान हैं. उन्‍होंने एचएमटी, विजय नांदेड, नांदेड 92, नांदेड हिरा, डीआरके, नांदेड चेन्नूर, नांदेड दीपक, काटे एचएमटी आणि डीआरके 2 यह नौ धान प्र‍जाति विकसित की. उनकेे द्वारा व‍िकस‍ित धान किसानों के लिए कम जमीनपर ज्‍यादा फसल उगाने में क्रांतिकारी साबित हुई. उनके निधन से देश ने एक प्रतिभाशाली कृषि संशोधक खोया है.

एमएनटी न्‍यूज नेटवर्क उन्‍हें विनम्र अभिवादन करता है.

Dadaji Ramaji Khobragade in English

68-yr-old Dadaji Ramaji Khobragade is a Indian Buddhist farmer with a grouse. Ten years ago he shot to fame for breeding a variety of rice called Hmt which went on to become one of the highest yielding varieties in the region.It even became popular in neighbouring states of Andhra Pradesh and Madhya Pradesh. In Maharashtra it is grown in over 6,88,000 hectares ..
Dadaji Khobragade, HMT Rice Variety Developer

” When my neighbours took it to the market to sell it, the traders could immediately tell this was different variety and asked for its name. One of the farmers was wearing an Hmt watch and decided to call the rice variety that. Eversince it been called Hmt rice”.

Grassroots innovation like Khobragade’s are classic example of necessity being the mother of invention. And yet he is a bitter man today. While the seeds he helped develop sell for as much as 1500 rupees a quintal he’s got nothing. Leave alone money even recognition seems to be taking its time finding him.

By 1994 when Hmt became a rage with paddy farmers as far as Chattisgarh and Andhra Pradesh. The local agricultural university took 5 Kgs kg of HMT seeds from Khobragade saying that the rice station wanted to experiment with it. In 1998, the university released a new variety in the State called Pkv hmt after the researchers say they “purified” the seed they had obtained from Khobragade.

Sharad Nimbalkar, Vc Punjabrao Krishi Vidyapeeth says”The original seed may have come from Khobragade but now it is entirely the University’s intellectual property.”

In a tragic twist of fortunes. Khobragade has fallen on hard time. He has to work for daily wages to support his seven-member family but his grassroots research has helped fellow farmers.

Dadaji Khobragade, Rice Variety Developer says “I have worked very hard to develop this new variety of paddy. I though this will help me and my family economically. But today we lead a hard life due to poverty.”

Bhimrao Shende, Neighbour says ” In 1990 we all had haystack roofs… Now we have pucca roofs and better homes and our village’s economic condition has improved because of his high yield producing seeds”.

Khobragade has not lost hope. He showed us his six new varieties of rice. Each of them carefully framed and labelled. One of them is called Drk after himself. He’s asked the government to convince the university to allow him to claim royalty for his variety of rice.

Pic1: D R Khobragade indiginious research thesis, who is going to hear him?
Nagpur: He fought for his rights but could never quite get his due. Dadaji Ramaji Khobragade, the inventor of HMT-Sona and ten other popular rice varieties died on Sunday at the Search hospital in Gadchiroli. The Dalit farmer, who won global acclaim for his innovations, had suffered a crippling paralytic attack a month ago.

He is survived by his son, daughter-in-law, and grandchildren.

The 80-year-old had been unwell for the past six months. He was frail and his listening capabilities were hampered.

For his work and farm innovations, Dadaji earned a lot of goodwill and support from many quarters including institutions and individuals. This was something that kept pushing him to work, even in his old age.

Dadaji was active until last year when he would make at least one visit to his farm every day. The veteran stopped working when his body would no longer back up his mind and his ideas.

During his childhood, he reared the village cattle and could never go to school. As an adult, he invented 11 popular rice varieties that occupy vast stretches of paddy land in central India.

HMT-Sona gives an average yield of 40–45 quintals per hectare and has short grains, high rice recovery and good aroma. The variety is now marketed in Andhra Pradesh, Gujarat,
Chhattisgarh, Madhya Pradesh and Maharashtra. Chinnour, Nanded-92, Nanded-Hira, Vijay-Nanded, Dipak-Ratna and the latest DRK-I and II, were some of his other finds with an average yield of about 20 quintals per acre in rain-fed conditions.

For many years, the octogenarian lived in a dingy hut in Chandrapur’s Nanded village. A few years ago, with the money from his awards and help from a few people, Dadaji built a house that also became his seed godown. Awards, medals and citations would hang by the walls in a room.

He first shot to fame when he accused the state-run Punjabrao Krishi Vidyapeeth (PKV) for taking credit for the brand that he had originally bred on his farm and given to the university scientists. This was in early 2000s.

While Dadaji claimed the PKV had appropriated his variety, the PKV held that sourced it from him and significantly improved the variety with their scientific inputs. The issue remains unresolved till date. PKV never officially gave Dadaji his credit in its varietal release proposal.

The National Innovation Foundation (NIF) recognised his work in 2003-04 and the Maharashtra government gave him the Krishi Bhushan and Krishi Ratna awards for his innovations. One of his varieties called Chinnour is akin to the Basmati of the north. He named his latest variety after himself: DRK.

In 2010, Dadaji’s name figured in the Forbes list of top seven Indian rural entrepreneurs, after it was picked up by the IIM-Ahmadabad professor and founder of the Honey Bee Network Anil Gupta. Dadaji could not make any sense of what it meant. “I am happy, but I don’t know what it means to me and to my fellow farmers,” he said.

When I first met Dadaji in August 2005, he recounted to me a number of heists that took place on his farm every day. Someone stole pumpkins one day; the other day, it would be a wooden cot that he kept for himself. In summers, people stole wild berries and even rice.

He wasn’t bothered about those thefts as much as he was about the fact that the PKV never quite officially acknowledged the HMT-Sona as his discovery. Even the name was given by Dadaji when he went to the market in Mul town, back in early 1990, and a trader asked him to suggest a name for the rice variety.

“I’d wear an HMT-Sona watch on my wrist,” Dadaji recounted in my first interview. “I looked at it and told the trader ‘let it be named HMT-Sona’.” It took the consumers by a storm for its fragrance and taste.

In 1983, Dadaji noticed three yellow-coloured strains of paddy corns in his farm. “They were different," he told me. The innovator preserved them and sowed them again on his farm the following year. The rice it yielded was soft and tasty with better oil contents. He repeated the process over seven years with the selection method. A decade later, it became a hit with the local farmers.

Dadaji had bred this particular variety from the Patel-3 variety that he would plant on his fields. He had an eye for the best grain and a heart for farming. As his son Mitrajeet would once tell us: “Dadaji spoke to his paddy strains as if they were his kids, softly and lovingly.”

He was uneducated, but he was deeply inspired by Dr Babasaheb Ambedkar. Dadaji was a Mahar by caste and an Ambedkarite by political belief. “I stopped skinning the cattle on the call of Dr Ambedkar,” he once told me. “I never got to see Babasaheb, but my generation came out of our past shadows because of him.”

During one of our interactions at his home, Dadaji told me how he was landless once. “This present land is my daughter-in-law’s land. One-and-a-half acres, it came to her as property from her side.” That land had dual purposes — it was his family’s sustenance and his lab.

“No one told ever me how to breed the varieties; I kept doing it out of my love for the best grains.”

Like a true parent breeder, he could separate the real from the fake. “This is not my rice,” he once told me of a variety I had taken to him. A Nagpur grocer sold it as HMT-Sona. Dadaji said it wasn’t.

He gave me a few kgs of the original, the rice he had found on his farm and bettered it. It tasted much better and was qualitatively different from the one I had bought from a shop in my home city.

Dadaji once tried experimenting with paddy and turmeric as an inter-cropping system on his farm. He succeeded with the yields but held commodity prices were a key factor. “Farmers will remain poor unless they get remunerative prices and capital to start allied activities,” he told me.

In 2006, Dadaji took on the Vilasrao Deshmukh-government for having gifted him with a fake gold medal. Dadaji discovered that a 14-carat gold medal that he got from the government as part of the Krishi-Bhushan award package was actually made of sub-standard silver whose value was no more than Rs 500. “I am shocked,” an agitated Dadaji said then. “Why insult us like this?”

Dadaji was presented a 50 gram 14-carat gold medal, cash prize of Rs 25,000 and a citation from the Maharashtra Governor for his achievement. “I used all my cash awards to buy some land for research work.” When he wanted to sell the gold medal to buy a motor-pump, he was told the medal was actually a dud.

Dadaji returned his award in anger, prompting other medallists to return their awards and the state government to launch an inquiry and apologise to the farmers by reinstating their awards with original gold medals. Dadaji favoured the intellectual property rights to be bestowed upon farmers like him.

Seed savers like him were crucial to food security and seed diversity, he once told me at his home. “Farmers must not merely complain of the problems,” he held. “They should also try to be a solution.”

Ganesh Prasad
Born 15 November 1876

Died 9 March 1935 (aged 58)

Agra, Uttar Pradesh, India
Nationality Indian

Known for Establishing the culture of organised mathematical research in India

Notable work A Treatise on Spherical Harmonics and the Functions of Bessel and Lame

Title Hardinge Professor of Mathematics

Ganesh Prasad (15 November 1876 – 9 March 1935) was an Indian mathematician who specialised in the theory of potentials, theory of functions of a real variableFourier series and the theory of surfaces. He was trained at the Universities of Cambridge and Göttingen and on return to India he helped develop the culture of mathematical research in India. The mathematical community of India considers Ganesh Prasad as the Father of Mathematical Research in India. He was also an educator taking special interest in the advancement of primary education in the rural areas of India.

Early days

Ganesh Prasad was born on 15 November 1876 at Ballia, Uttar Pradesh. He obtained the B.A. degree from Muir Central CollegeAllahabad, M.A. degree from the Universities in Allahabad and Calcutta and the D.Sc. degree from Allahabad University. After teaching at the Kayasth Pathshala, Allahabad, and at the Muir Central College, Allahabad, for about two years, he proceeded to Cambridge for higher studies and research. While at Cambridge he became acquainted with mathematicians like E.W. Hobson and Andrew Forsyth. He also sat, though unsuccessfully, for the Adams prize competition.

Later he moved to Göttingen where he was associated with Arnold SommerfeldDavid Hilbert and Georg Cantor. In Göttingen, Prasad showed his paper titled On the constitution of matter and the analytical theories of heat, the one he had submitted for the Adams prize competition, to Felix Klein, who appreciated it very much and arranged its publication in the Göttingen Abhandlungen. Ganesh Prasad spent altogether about five years in Europe.

Mathematical career

Prasad returned to India from Europe in 1904 and was appointed professor of mathematics at the Muir Central CollegeAllahabad. Within a year of his appointment at Allahabad, Prasad was sent to the Queen's College, Banaras and he continued there till 1914 when he was invited to head the mathematics department of Calcutta University. Ganesh Prasad was the Ras Behari Ghosh Chair of Applied Mathematics of Calcutta University (he was the first person to occupy this Chair) from 1914 to 1917 and Hardinge Professor of Mathematics in the same University from 1923 till his death on 9 March 1935. In between these two assignments he served Banaras Hindu University as professor of mathematics (1917–1923). While at Banaras, he helped found the Banaras Mathematical Society. Ganesh Prasad was elected President of the Calcutta Mathematical Society and the Vice-President of the Indian Association for Advancement of Science, Calcutta in 1924 and continued in the same position till his death. He was a founder member of the National Institute of Sciences, India, which has now been rechristened as the Indian National Science Academy. Ganesh Prasad authored 11 books including A Treatise on Spherical Harmonics and the Functions of Bessel and Lame and over fifty research papers in mathematics.

Other areas of work

Ganesh Prasad worked hard for the promotion of education in general in the rural areas of Uttar Pradesh. He was instrumental in the introduction of compulsory primary education in villages in Uttar Pradesh. He donated from his private savings an amount of Rs. 22,000 for the education of girls in Ballia. He also donated an amount of Rupees two hundred thousand for establishing prizes for the toppers at the M.A. and MSc examinations of the Agra University. He donated large amounts of money to the Allahabad and Banaras Universities also.

Died 7 July 2006 (aged 87)

Madurai, Tamil Nadu, India
Other names Dr V
Occupation ophthalmologist

Govindappa Venkataswamy (1 October 1918 – 7 July 2006) popularly known as 'Dr V.' was an Indian ophthalmologist who dedicated his life to eliminate needless blindness. He was the founder and former chairman of Aravind Eye Hospitals. He is best known for developing a high quality, high volume, low-cost service delivery model that has restored sight to millions of people. Since inception, Aravind Eye Care System (a registered non-profit organisation) has seen over 55 million patients, and performed over 6.8 million surgeries. Over 50% of the organisation's patients pay either nothing or highly subsidised rates. Its scale and self-sustainability prompted a 1993 Harvard Business Case Study on the Aravind model.

Venkataswamy was permanently crippled by rheumatoid arthritis at age 30. He trained as an ophthalmologist, and personally performed over 100,000 eye surgeries. As a government servant he helped develop and pioneer the concept of eye camps and received a Padma Shri from the Government of India in 1973.

In 1992, Venkataswamy and partners of Aravind founded Aurolab, an internationally certified manufacturing facility that brought the price of the intraocular lens down to one-tenth of international prices, making it affordable for developing countries. Today, Aurolab manufactures ophthalmic pharmaceuticals, instruments and equipment, in addition to intraocular lenses, and exports to 160 countries worldwide. In 1996, under Venkataswamy's leadership, the Lions Aravind Institute for Community Ophthalmology (LAICO) was founded. LAICO is a training and consulting institute that has helped replicate the Aravind model in 347 hospitals across India and 30 other developing countries

Early life and career

Born in 1918 in a poor farming village, Venkataswamy was the eldest of five children in a farming family. He walked two kilometres to school each day and his early lessons were written in sand from the riverbed. There were no doctors in his village, and by the age of 10 he had lost three cousins due to pregnancy-related complications. The untimely deaths spurred his decision to become a doctor. As a young man, he followed the teachings of Mahatma GandhiSwami Vivekananda and Sri Aurobindo. Venkataswamy earned a Bachelor of Science in chemistry in 1938 from American College, Madurai. In 1944 he received his medical degree from Stanley Medical College in Madras, graduating second in his class. In 1951 he qualified with an MS in Ophthalmology at Government Ophthalmic Hospital, Madras. He was in medical school when his father died, leaving him the head of the family. After receiving his medical degree, Venkataswamy served as a physician with the Indian Army from 1945 to 1948. He was discharged after contracting a rare form of rheumatoid arthritis. He was 30-years-old at the time. The condition permanently twisted his fingers out of shape, and left him bed-ridden for two years. Upon his return to medicine his condition barred him from training in obstetrics, his chosen field. He decided to train instead in ophthalmology.

In 1956, he was appointed head of the Department of Ophthalmology at the Government Madurai Medical College and eye surgeon at the Government Erskine Hospital in Madurai. He held these posts for 20 years. In 1965, at a conference on rehabilitation for the blind, Venkataswamy met Sir John Wilson, founder of the Royal Commonwealth Society for the Blind (later known as Sightsavers International). The latter had been blinded in childhood by an accident in his school chemistry lab. The two established a lifelong friendship. Venkataswamy. credits Sir John Wilson's mentorship for helping him develop a global view on blindness prevention. The two men met with then Prime Minister, Indira Gandhi, to help launch India's National Program for the Control of Blindness. Venkataswamy then led Tamil Nadu's initiative to establish mobile eye camps that took sight-restoring services into rural India. He established a rehabilitation centre for the blind in 1966, and an Ophthalmic Assistants Training program in 1973. In his clinical work, Venkataswamy personally performed over one hundred thousand successful eye surgeries. With Wilson's support, Venkataswamy also started India's first residential nutrition rehabilitation centre in Madurai where children with potentially blinding Vitamin A deficiency received treatment, while their mothers were given training in how to grow and prepare nutritional meals.

Study of Aravind Model

Venkataswamy pioneered mobile eye camps with the government, and later implemented this practice at Aravind. Teams of doctors and nurses from Aravind regularly visit rural villages where they conduct 'eye camps' that screen patients for vision impairments. Those requiring glasses receive them on site. Patients requiring surgery are brought back to an Aravind hospital, where they receive surgery, room and board, return transport and a follow up visit at no charge. Each year Aravind hosts over 2,500 camps, averaging 40 camps every week with 500 community partners.

Venkataswamy introduced a tiered pricing system at Aravind. There are no income assessments or eligibility criteria for free or subsidised treatment. Patients decide whether they would like to access free, subsidised or paid services. Within this system, a cataract operation ranges from free to a little under US$900 (~ Rs. 53,700) based on the accommodations associated with the surgery and the type of lens implanted. Patients can self-select services and room type based on preference and ability to pay, without compromising clinical outcomes. In practice, one patient who pays, subsidises the no-frills surgeries and pre- and post-operative care of two non-paying patients.

Nurses, known within the Aravind system as Mid-Level Ophthalmic Personnel (MLOP), are trained extensively in discrete skills, and specialise in different areas of the hospital work flow, including administrative work, diagnostics, nursing and counseling. The MLOPs are primarily women who are high-school graduates recruited from surrounding villages. In the operating room each surgeon, is assisted by four MLOPs. With stream-lined processes, Aravind averages 2,000 surgeries per doctor per year compared to a national average of 400. Tina Rosenberg for The New York Times writes, "Aravind can practice compassion successfully because it is run like a McDonald’s with assembly-line efficiency, strict quality norms, brand recognition, standardization, consistency, ruthless cost control and above all, volume. Each year, Aravind does 60 percent as many eye surgeries as the United Kingdom’s National Health System, at one one-thousandth of the cost."

Since 1993 Harvard Business School has distributed more than 150,000 copies of 'In Service for Sight' (their original case study on the Aravind model) to the top twenty business schools in the United States.

Founding of Aravind

In 1976, at the mandatory retirement age of 58, Venkataswamy founded the Aravind Eye Hospital in Madurai, Tamil Nadu with his four siblings, G. Nallakrishnan, R. Janaky, G. Srinivasan, G. Natchiar and their respective spouses, Meenakshi, R.S. Ramasamy, Lalitha S. and P. Namperumalsamy. Together, they formed the Govel Trust to manage the hospital, and defined Aravind's mission: To eliminate needless blindness by providing high quality and compassionate eye care affordable for all. P. Namperumalsamy's sister, P. Vijayalakshmi and her husband, M. Srinivasan also joined his work. In the initial years he and his team faced many financial difficulties. Venkataswamy is the founding member of Seva Foundation (a US-based non-profit organisation), that partnered with Aravind in the early years by widening the organisation's access to the latest technology, and skilled volunteers. Seva continues to collaborate with Aravind in various aspects of eye care management, education, and research. Today, the Aravind Eye Care System encompasses a growing network of eye care facilities which include seven tertiary centres, six secondary hospitals, six outpatient eye examination centres and seventy primary eye examination facilities, as well as a post-graduate training institute for ophthalmology, an international eye research centre, eye bank, training and consulting institute and manufacturing facility.

Personal life

Venkataswamy never married. He lived with his younger brother G. Srinivasan (Aravind Eye Care System's Director of Finance and Building) and his family. Today, over 35 members across three generations of Venkataswamy's family work at Aravind. Venkataswamy was a Gandhian and a disciple of the spiritual teachers Sri Aurobindo and the Mother. Former President of India A.P.J. Abdul Kalam, a friend of his, wrote, "In the Aravind experience I see the path we need to take, a transformation of life into a powerful instrument of right action."

Quotes of Govindappa Venkataswamy
When we grow in spiritual consciousness, we identify ourselves with all that is in the world, and there is no exploitation. It is ourselves we are helping. It is ourselves we are healing.
Intelligence and capability are not enough. There must be the joy of doing something beautiful."
To some of us bringing divine consciousness to our daily activities is the Goal. The Hospital work gives an opportunity for this spiritual growth. In your growth you widen your consciousness and you feel the suffering of others in you.
Aravind Hospital aims at bringing higher consciousness to transform mind and body and soul of people. It is not a mechanical structure repairing eyes. It has a deeper purpose. It is not about buildings, equipment, money or material things, but a matter of consciousness.
You don't just find people. You have to "build" them.
To keep the mind absolutely still, to understand the reaction, impulse and attitude and to work from the Soul is the Aim.
To get things done in a big and permanent way it must be done spiritually.

Thesis Chromosome Studies in Nicandra physaloides

Janaki Ammal Edavalath Kakkat (4 November 1897 – 7 February 1984) was an Indian botanist who worked on plant breeding, cytogenetics and phytogeography. Her most notable work involved studies on sugarcane and the eggplant (brinjal). She also worked on the cytogenetics of a range of plants and co-authored the Chromosome Atlas of Cultivated Plants (1945) with C.D. Darlington. She took an interest in ethnobotany and in plants of medicinal and economic value from the rain forests of Kerala, India. She was awarded a Padma Shri by the Indian government in 1977.


E.K.Janaki was born in Tellicherry, Kerala. Her father was Diwan Bahadur Edavalath Kakkat Krishnan (sub-judge) and Devi Kuruvayi. Her mother was an illegitimate daughter of John Child Hannyngton (colonial administrator and Resident at Travancore) and Kunhi Kurumbi Kuruvai. Frank Hannyngton, Indian civil servant and entomologist, was thus a half-brother of Janaki Ammal's mother.

Janaki did her primary schooling at Sacred Heart Convent in Thalassery followed by Queen Mary's College, Madras. She obtained an Honours degree in Botany from the Presidency College and then moved to the University of Michigan in 1924, obtaining a masters degree in botany in 1926 with a Barbour Scholarship. She returned to India to work as a professor in the Women's Christian College in Madras for a few years, returned to the University of Michigan as an Oriental Barbour Fellow and obtained a PhD in 1931. Her thesis was titled "Chromosome Studies in Nicandra Physaloides". The University also awarded her an honorary LLD in 1956.

On her return, she became Professor of Botany at the Maharaja’s College of Science in Trivandrum (Now, University College,Trivandrum) and served there as Assistant Professor for two years between 1932 and 1934. Janaki then joined the John Innes Institute, Merton, London, where she worked with C D. Darlington, who would become a long-term collaborator. She then worked at the Sugarcane Breeding Institute in Coimbatore and worked with C.A. Barber. Her worked involved the production of hybrids including several intergeneric crosses including the variety SG 63-32.

In 1939 she went to attend the 7th International Congress of Genetics, Edinburgh and was forced to stay on due to World War II. She then spent the next six years at the John Innes Centre as an assistant cytologist to C.D. Darlington. Together they published a Chromosome Atlas of Cultivated Plants in 1945. She was invited to work as a cytologist at the Royal Horticultural Society, Wisley from 1945 to 1951. During this period she studied Magnolias, their cytology and conducted experiment on their hybridization. The Indian government invited her to reorganize the Botanical Survey of India, and she was appointed as the first director of the Central Botanical Laboratory at Allahabad. From 1962, she served as an officer on special duty at Regional Research Laboratory in Jammu. She also worked briefly at Bhabha Atomic Research Centre at Trombay and then settled down in Madras in November 1970, working as an Emeritus Scientist at the Centre for Advanced Study (CAS) in Botany, University of Madras. She lived and worked in the Centre’s Field Laboratory at Maduravoyal until her demise in February 1984.


As an expert in cytogenetics, Janaki joined the Sugarcane Breeding Station at Coimbatore to work on sugarcane biology. At that time, the sweetest sugarcane in the world was the Saccharum officianarum variety from Papua New Guinea and India imported it from Southeast Asia. In a bid to improve India’s indigenous sugarcane varieties, the Sugarcane Breeding Station had been set up at Coimbatore in the early 1920s. By manipulating polyploid cells through cross-breeding of hybrids in the laboratory, Janaki was able to create a high yielding strain of the sugarcane that would thrive in Indian conditions. Her research also helped analyse the geographical distribution of sugarcane across India, and to establish that the Saccharum Spontaneum variety of sugarcane had originated in India. However, her status as a single woman from a caste considered backward created irreconcilable problems for Janaki among her male peers at Coimbatore. Facing caste and gender based discrimination. Impressed by her work, the Royal Horticulture Society invited Janaki to work as an assistant cytologist at their campus at Wisley, near Kew Gardens, famous for its collection of plants from around the world.

During the years she spent in England, Janaki did chromosome studies of a wide range of garden plants. Her studies on chromosome numbers and ploidy in many cases threw light on the evolution of species and varieties. The Chromosome Atlas of Cultivated Plants which she wrote jointly with C. D. Darlington in 1945 was a compilation that incorporated much of her own work on many species. At the Society, one of the plants she worked on was the magnolia. To this day, in the Society’s campus at Wisley there are magnolia shrubs she planted and among them is a variety with small white flowers named after her: Magnolia kobus 'Janaki Ammal'. A flower celebrated in Japanese and Chinese legends, the blooms of this variety are made up of fused sepals and petals called ‘tepals’. Today, only a few nurseries in Europe cultivate the variety.

Janaki also worked on the genera SolanumDaturaMenthaCymbopogon and Dioscorea besides medicinal and other plants. She attributed the higher rate of plant speciation in the cold and humid northeast Himalayas as compared to the cold and dry northwest Himalayas to polyploidy. Also, according to her, the confluence of Chinese and Malayan elements in the flora of northeast India led to natural hybridisation between these and the native flora in this region, contributing further to plant diversification.

Following her retirement,Janaki continued to publish the original findings of her research focusing special attention on medicinal plants and ethnobotany. In the Madras University Field Laboratory where she lived and worked she developed a garden of medicinal plants.

As a geneticist working for the Royal Horticultural Society's Garden Wisley in the early 1950s, Dr. Janaki was investigating the effects of colchicine on a number of woody plants, including Magnolia, where a stock solution in water is made up and applied to the growing tip of young seedlings once the cotyledons (seed leaves) have fully expanded. Doubling of chromosomes occurs, giving the cells twice the usual number. The resulting plants have heavier textured leaves; their flowers are variable, often with thicker tepals, helping them last longer. As Magnolia kobus seeds were available in quantity, a number of seedlings were treated by Dr Janaki Ammal and ultimately planted on Battleston Hill at Wisley.

Awards and honours

Janaki is mentioned among Indian Americans of the Century in an India Currents magazine article published on 1 January 2000, by S.Gopikrishna & Vandana Kumar: "In an age when most women didn't make it past high school, would it be possible for an Indian woman to obtain a PhD at one of America's finest public universities and also make seminal contributions to her field?!" Kerala-born Janaki was arguably the first woman to obtain a PhD in botany in the U.S. (1931), and remains one of the few Asian women to be conferred a DSc (honoris causa) by her alma mater, the University of Michigan. During her time at Ann Arbor she lived in the Martha Cook Building, an all-female residence hall and worked with Harley Harris Bartlett, Professor at the Department of Botany.

She was elected Fellow of the Indian Academy of Sciences in 1935, and of the Indian National Science Academy in 1957. The University of Michigan conferred an honorary LL.D. on her in 1956 in recognition of her contributions to botany and cytogenetics said: "Blest with the ability to make painstaking and accurate observations, she and her patient endeavours stand as a model for serious and dedicated scientific workers." The Government of India conferred the Padma Shri on her in 1977. The Ministry of Environment and Forestry of the Government of India instituted the National Award of Taxonomy in her name in 2000.

She produced many hybrid brinjal varieties (Indian name for eggplant).

Two awards were instituted in her name in 1999: EK Janaki Ammal National Award on Plant Taxonomy and EK Janaki Ammal National Award on Animal Taxonomy.[12] There is herbarium with over 25000 plant species in Jammutawi named after Janaki Ammal. The John Innes Centre offers a scholarship to PhD students from developing countries in her name.

Plants and Animals in her name

To honour her work in plant breeding, the Royal Horticultural Society, Wisley, U.K.named a variety of Magnolia she created as Magnolia Kobus 'Janaki Ammal'.[15] In 2018, to celebrate her remarkable career and contribution to plant science, two rose breeders, Girija and Viru Viraraghavan bred a new rose variety which they named E.K. Janaki Ammal.

The name Janakia arayalpathra is also after her.

Sonerila janakiana, a species of plant in the family Melastomataceae, is named after her. 

Dravidogecko janakiae, a species of geckos found in India is also named after her.

Spouse Laxmimani Debi

Keshab Chandra Nag or K.C. Nag [ Bengali কেশবচন্দ্র নাগ ] (10 August 1893 – 6 February 1987), was an Indian Bengali mathematician, author of various mathematics textbooks and educator.

Early life

K. C. Nag was born in Nagpara, GurapHooghlyBengalBritish India (present-day West BengalIndia) on the holy day of Rath Yatra, 10 August 1893. His Father was Raghunath Nag and Mother Khiroda Sundari Debi. He lost his father at an early age of three. He was only cared for by his mother.


Keshab Chandra Nag started his education in a Bengali Medium School at his Village Gurap. At that time that was the only school at Gurap. From Class VII he changed his school to Bhastara Yojneshshar Uccha Vidyalaya (Yojneshshar High School), 3 miles from his village. He would start walking early in the morning to reach his school and came back home at evening every day. In Class IX he got admitted to Kishenganj High School. In 1912, he passed the entrance examination with a First Class and joined Ripon College (now Surendranath College), Kolkata, in Science. In 1914, he passed the I.Sc examination with a First Class. After this due to severe financial crisis he had to discontinue his education and start earning money.
Working life

He started his career as Third Master in Bhastara Yojgeshshar Uccha Vidyalaya. He also did private tuitions when teaching there. His family was dependent on him but he resigned from his job to pursue higher studies. In 1917 he passed B.A with Mathematics and Sanskrit. He then received a job offer from Kishenganj High School as a Mathematics Teacher. He taught for some time in that School, after which he got another offer from Baharampur Krishnanath Collegiate School and joined the school as a mathematics teacher.[2] In 1919 he got Diksha from Ma Sarada Devi. During that time the Maharaja of Kasimbazar (CossimbazarManindra Chandra Nandi was a great admirer of Keshab Chandra. Maharaj allowed Keshab Chandra to use his vast library. In that library, he studied extensively about the history of India and especially the history of mathematics. At first, he lived in a mess at Rosa Road in Kolkata. From 1964 he started to live at his own house at Gobinda Ghoshal Lane in South Kolkata.
Meeting with Ashutosh Mukhopadhyay

In 1905 Sir Ashutosh Mukhopadhay established Mitra Institution (Branch) in Bhowanipore so that the students of South Kolkata can also get chance to study in that school. In 1906 Sir Ashutosh Mukhopadhay became the Vice Chancellor of Calcutta University and tried to bring various teachers from different parts of India to establish Calcutta Universities as one of the best university of India. Similarly, he tried to bring teachers to Mitra Institution (Branch). Sir Ashutosh heard about Keshab Chandra, and he took him to Mitra Institution, Bhabanipur as a mathematics teacher. Due to his way of teaching mathematics Keshab Chandra came very close to Sir Ashutosh . Dr. Shyamaprasad Mukhopadhay son of Sir Ashutosh became a very good friend of Keshab Chandra and requested him to join politics which Keshab Chandra declined.
Mathematics books

In 1909 Sir Ashutosh along with his teacher Shyamacharan Bose wrote a book titled "Arithmetic for Schools". After the death of Sir Ashutosh, his son Shyamaprasad Mukhopadhay took the initiative to revise that book and requested Keshab Chandra to help him. After an untiring effort of Keshab Chandra Nag along with a few mathematicians in 1937, a revised edition of the book was published in the name "Patiganith". Kabisekhar (কবিশেখর) Kalidas Roy was a colleague of Keshab Chandra Nag. There was a regular gathering of various stalwarts in the field of academics and literature like Sarath Chandra Chattopadhyay, Premendra Mitra etc. was held at Kabisekhar's House, Keshab Chandra was a regular to that gathering. One day Sarat Chandra Chattopadhyay requested Keshab Chandra to write a mathematics book. After a few days, the same request came from Kabisekhar. Keshab Chandra was very confused whether to write the book or not and ultimately decided to write it for the benefit of students. His first book was Nava Patiganit (নব পাটিগণিত) from U.N. Dhar & Sons. Within a short time, this book became very famous among the students of class five and six. In the year 1942 Matric Mathematics, one of the famous books of K.C. Nag was published by the publisher Calcutta Book House. After this, he wrote many more books for various classes from IV to XII. These books were published in Bengali, English, Hindi, Urdu, and Nepali language. His younger son Late Taraprasad Nag started his own publishing house named "Nag Book House". This publishing house has now been renamed as " Nag Publishing House" and is managed by his grandson Dr. Tridibesh Nag. Tridibesh did his B.E. in Electrical Engineering and M.E from Jadavpur University. After this, he took over the publication and took every measure to ensure that the mathematics books by the legendary "K.C.Nag" never lost its reputation. His sole motive was to see to it that the students are not deprived of the privilege of learning mathematics from K.C. Nag's maths books. K.C. Nag's books from class 4–12 are the books which the students aspiring to excel in every walk of life had depended on at some time or other for the past three generations. Tridibesh formed a board consisting of eminent professors, school teachers, examiners, and successful students in order to revise the book from time to time.

Kattungal Subramaniam Manilal (Malayalam: കാട്ടുങ്ങൽ സുബ്രഹ്മണ്യം മണിലാൽ) (born 17 September 1938) is an Emeritus of the University of Calicut, a botany scholar and taxonomist, who devoted over 35 years of his life to research, translation and annotation work of the Latin botanical treatise Hortus Malabaricus. This epic effort brought to light the main contents of the book, a wealth of botanical information on Malabar that had largely remained inaccessible to English-speaking scholars, because the entire text was in the Latin language.

In January 2020, Manilal was conferred with the Padma Shri award, the fourth-highest civilian honour of India, for his contribution in the field of Science and Engineering.

Despite the existence of Hendrik van Rheede's Hortus Malabaricus over the last three centuries, the correct taxonomic identity of many plants listed in Hortus Malabaricus, their medicinal properties, methods of use, etc., as described and codified by renowned traditional medical authorities of 17th century India remained inaccessible to English language based scholars, until Manilal commenced publication of research papers and books on Hortus Malabaricus.

Manilal's efforts ultimately resulted in an English edition of Hortus Malabaricus, for the first time, 325 years after its original publication from Amsterdam. The English edition contains a word by word translation of all the twelve volumes of the book, retaining the original style of language. Medicinal properties of plants are translated and interpreted, with commentaries on their Malayalam names given by Van Rheede. In addition, the correct scientific identity of all plants, acceptable under ICBN are set out along with their important synonyms and basionyms.

Whilst the scope of Manilal's contributions to botany extend far beyond the research and publications around Hortus Malabaricus, his research work on Hortus Malabaricus alone are of botanical and socio-historic significance, and can be broadly classified under two heads:

Botanical and Medicinal aspects of Hortus Malabaricus; and
Historical, Political, Social and Linguistic aspects of Hortus Malabaricus.

Manilal has over 198 published research papers and 15 books to his credit as author and co-author. He and his associates have credits to discovering over 14 species of flowering plants, varieties and combinations new to science. Dr. Manilal is the Founder President of the Indian Association for Angiosperm Taxonomy (IAAT).

Birth, early life and interest in Hortus Malabaricus

Manilal was born in Cochin on 17 September 1938. He is one of three children born to his parents; father Advocate Kattungal A. Subramaniam (b:1914~d:1973) and mother K. K. Devaki (b:1919~d:1989). Manilal's father, K. A. Subramaniam, was besides being a practising advocate, also a writer, who authored the biography of Sahodaran Ayyapan. Manial's Kattungal family members are natives of North Paravur in Kerala, India.

As a young boy, Manilal's interest in Hortus Malabaricus was inspired by his father, whose avid reading habits and enthusiasm for sociology exposed Manilal to a collection of books, and more specifically newspaper cuttings on Hortus Malabaricus during the late 1940s and 1950s.

Manilal schooled initially at the Government Boys’ High School, Kodungallur and later at the Government S.R.V. Boys’ High School, Ernakulam. He enrolled for undergraduate studies in Botany at the Maharaja's College, Ernakulam, following which, he secured MSc Botany and PhD Degrees from University Teaching Department, Sagar, in Madhya Pradesh.

During his post-graduate studies, while on a study tour to the Forest Research Institute in Dehra Dun, Manilal was able to see, for the first time, a set of volumes of the original Hortus Malabaricus. This was set of volumes acquired by the Institute's library during the days of the British Raj, when the Institute was called the Imperial Forest College. Manilal remarks “it fired my imagination!” on seeing a Latin book in which the names of plants were also written in native Malayalam language. Manilal maintained his interest in the book through his studies and professional life until 1969, when he commenced serious work on the transliteration of Hortus Malabaricus.

He presently stays in Kozhikode.

Major research and academic achievements
Botanical and medicinal aspects of Hortus Malabaricus
Frontispiece of the original Latin Hortus Malabaricus

As Hortus Malabaricus is a pre-Linnaean book, the scientific names of plants, equivalent to local Malayalam names, were not included. Since voucher specimens for the book are also not known to exist, the correct identity of many of the plants described was unclear and not verifiable to original specimens. Earlier attempts, over three centuries, by European and Indian botanists to correctly identify all specimens were futile. Under two research projects; one sponsored by the U.G.C. (1975–1978) and the other by the Smithsonian Institution (1984–1987), Manilal collected all plants, described in Hortus Malabaricus, from localities in Malabar from where they were originally collected in the 17th century. Specimens were subjected to detailed studies and their correct identities were established in consultation with research institutes in Europe and USA. Based on this work, initially a concise reference book: An Interpretation of Van Rheede's Hortus Malabaricus, was published (with his collaborators) from Berlin (1988), by the IAPT. This remains the only book by Indian authors published by them (IAPT) till date and is an essential resource in study on the taxonomy of Southeast Asian plants.

Richard H. Grove, in his book 'Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins', states that Itty Achudan and his team selected the plants which were to be drawn and included in Hortus Malabaricus, with accurate identification and mentioning of vernacular (local) name of the plants. Itty Achudan also disclosed the medicinal and other uses of the plants which was known to him from his own experience as a herbal physician and from the 'palmleaf scripture' carried by his family as 'wealth of knowlede'. Achudan dictated the material, in his native Malayalam language, which was then translated into Latin. Hortus Malabaricus was compiled over a period of nearly 30 years and published in Amsterdam during 1678–1693.

Historical, political, social and linguistic aspects of Hortus Malabaricus

The compilation and publication of Hortus Malabaricus is intimately connected with the history of India, politics of the 17th century Netherlands and the then social conditions of Malabar. It is also an important source of information, and the oldest printed, authentic document, on the evolution of Malayalam language and script. Manilal studied these aspects for over 35 years bringing to light many interesting facts, some of which were included in his book: Botany & History of Hortus Malabaricus, published from Rotterdam and Delhi (1980). Another book, in Malayalam: A study on the role of Itty Achudan in the compilation of Hortus Malabaricus, was published from Kozhikode in 1996.

In the research paper published in the journal Global Histories, entitled 'Plants, Power and Knowledge: An Exploration of the Imperial Networks and the Circuits of Botanical Knowledge and Medical Systems on the Western Coast of India Against the Backdrop of European Expansionism', Malavika Binny states that Kerala had medical traditions that existed even prior to Ayurvedic tradition. As per the author, Ezhava Tradition of Healing Practices or 'Ezhava vaidyam',as it is called, was prominent among other medical traditions that existed in Kerala which involved a considerable contribution from Buddhism which was a major force from the sixth century to about the eleventh century. This Buddhist tradition of treatment of diseases using plants and the knowledge of the indigenous plants preserved by the Ezhavas was exploited by the European endeavour as suggested by the inclusion of Itty Achuden in the compilation of Hortus Malabaricus which is basically an ethno-botanical treatise on the flora of Malabar. Van Rheede's motivation to compile a book on the natural plant wealth of Malabar was to prove his belief that Malabar is self-sufficient in all requirements of military and commerce and hence that Cochin was better suited to be the south east Asian Headquarters of the Dutch overseas forces, compared to Colombo in Ceylon.

Information is also available in the text of Hortus Malabaricus not only about the vegetation in 17th century Malabar, but also about the general social conditions prevalent in those days. Significant inferences could also be drawn on some of these matters, indirectly from the data available in the book. Several research papers have been published by Manilal on these topics. Some more, particularly on the different Numerals and Numerical Systems used in Hortus and their sociological implications and significances in the Indian society, are under preparation.

Taxonomic and biodiversity studies in Kerala

Manilal pioneered taxonomic research and biodiversity studies in Kerala by training a genre of young taxonomists and identifying and cataloguing local plants in biodiversity-rich South India. A comprehensive study on the flora of the Greater Kozhikode area, consisting of the western sectors of the present day Kozhikode and Malappuram districts, covering an area of about 600 km2. was started in 1969. When completed in 1975, this work resulted in recording about one thousand species of flowering plants from the region, including several species recorded for the first time in India and importantly seven species new to science. Based on this work, a book: Flora of Calicut, was published (from Dehra Dun), and was taken as a model for subsequent research in India.

Research and revelations at Silent Valley

In the 1970s, when a proposal to build a hydro-electric project in Silent Valley triggered political controversy in Kerala due to an impending ecological disaster, the Government of Kerala appointed an experts’ committee of scientists to study, inventorise and report on Silent Valley's flora and fauna. The experts’ committee reported that the forests there could not be classified as tropical evergreen rainforests and that they contain only 240 species of flowering plants, which are also found elsewhere, and also that the Valley does not possess any new or rare species. Despite protests by environmentalists the State Government was about to go ahead with the project, only awaiting a clearance form the Central Government. At this juncture, the Department of Science and Technology (India) accepted Manilal's proposal to study the flora of Silent Valley and also required him to make a general study of the ecological status of the forests.

Over a four-year period commencing 1981, Manilal and research assistants undertook a study that brought to light:

A record of nearly 1,000 species of flowering plants;
Seven species new to science;
Several plants believed to be found only in Sri Lanka, Philippines, etc.;
Some species which were believed to be extinct, such as the Malabar Daffodil, which was last seen in 1850 by a scientist named Thomas C. Jerdon in Nilgiris;
Rare medicinal plants until then known to grow only in the islands of Philippines;
Many endemics of the neighbouring countries, where their existence was threatened, were found to have migrated to these forests for safety.

Further Manilal's study found that the Silent Valley forests fulfilled required parameters of tropical evergreen rainforests and, therefore, could be rightly so classified. His work was soon considered as model of how taxonomists could assist in solving socio-environmental issues; and many scientists and journalists from Europe, Africa and South America visited Silent Valley to study the working of this project.

Orchids of Kerala

Detailed studies of the orchid wealth of Kerala were started by Manilal in the late 1970s, including their taxonomy, anatomy, biology and floral evolution, which are essential for any further studies on their hybridisation. During these studies, contrary to the highest expectations, over 215 species of orchids were collected, including species that were till then believed to be extinct, like the ladies' slipper orchid Paphiopedilum druryii.

Origin and evolution of the flower

Manilal has led studies on the directions of evolution of flowers and the structure and anatomy of various floral organs in cash crops such as coconut palms, grasses (rice), orchidscompositae (sun flower), rubiales (coffee), etc. Many enigmas in these subjects could be solved, and results were published in around 45 research papers. These studies have, besides seeing the flower as the most significant part of the plant, with biological, commercial, aesthetic, evolutionary and taxonomic importance, also promoted success in hybridisation and breeding experiments, to create new high-yielding varieties.

Radioactive resistant marine phyto-planktonic algae

As the beaches in southern Kerala and Tamil Nadu (particularly in the Districts of Kollam and Nagarcoil) have natural deposits of radioactive minerals causing genetic damage to flora and fauna, Manilal undertook studies to familiarise with the techniques of research in the field of radiation ecology. These studies were undertaken at the Marine Biology Laboratory of North Wales University at Menai Bridge, Wales. The Royal Society of London granted Manilal a Visiting Scientist-ship for this work for two years in 1971–1972.

Two species of marine phyto-planktonic algae were discovered, which could withstand a very high degree of radioactivity. It was found that these species could absorb and adsorb as much as 40 times their body weight of the radioactive Thorium compounds from surrounding seawater, and continue to live normally. In the 1970s these findings were farfetched to be accepted for publication in a journal in U.K. However, on Manilal's return to India, a part of these findings was published in the journal Current Science (1975), by the Indian Institute of Science. About ten years later, some British scientists did a similar work and their results were published in the prestigious U.K. journal Nature, and wide publicity in the press as a biotechnological break-through. Dr. Manilal's experiments (and the subsequent work by the British scientists) show that such marine planktonic algae could be used to quickly and safely clean up ocean surfaces where radio-active materials have accumulated, by cultivating such algae in a specific area and later removing them from there.

Indian Association for Angiosperm Taxonomy (IAAT)

Manilal was instrumental in establishing the Indian Association for Angiosperm Taxonomy (IAAT). Manilal, as founder President, established IAAT in the year 1990 with its headquarters located at the Department of Botany, University of CalicutKozhikode, India. The IAAT works to promote the science of Angiosperm Taxonomy in India, to provide a common forum for Angiosperm taxonomists in India to organise meetings, hold discussions and exchange ideas on scientific and academic matters, and encourage collaborative work among taxonomists. The IAAT publishes a journal Rheedea (named after Hendrik van Rheede). The Indian Association for Angiosperm Taxonomy works as an affiliate of the International Association for Plant Taxonomy.

From 1969 Manilal commenced training research students in Taxonomy (leading to PhD degree in the subject), with a view to attain self-sufficiency in Taxonomy. During the years 1972–1998, he and his students discovered over 240 new species of flowering plants and several new records for India from Kerala, and published many research papers in Taxonomy in national and international journals.

Biomass Research Centre

Biomass Research Centre was established by Manilal in the University of Calicut, with funding from the Ministry of Non-conventional Energy Sources. The Centre does research and field experiments to establish the (taxonomic) identification of fast-growing fuel-wood trees suitable for various agro-climatic zones of Kerala.

Publication of the English and Malayalam versions of Hortus Malabaricus

Publisher's appeal for donation of royalties

Hortus Malabaricus as transliterated by Manilal was published in English and Malayalam languages in 2003 and 2008 respectively. Manilal's copyright, as author of the English and Malayalam versions, was bequeathed, free of royalties, to the publishers, the University of Kerala. This assignment of rights was a gesture by Manilal in good faith and in response to a specific appeal from the then Vice-Chancellor of the University of Kerala, that the University wanted to generate funds from this publication for utilisation of such royalty incomes toward re-publication of old Malayalam classical works, which are out of print, and not forecasted to generate a viable level of income due to limited sale of such classical works.

Book-release functions conducted by the publishers

In a recorded interview with Manilal in August 2008, he expressed his regret and frustration at the manner in which the publishers subjected him to digression from the publication project soon after he legally assigned his rights as author. Apparently there was a move to exclude Manilal's name from the book (2003), but was reinstated on account of questions raised by the academic community. On 14 August 2008, the University of Kerala officials again conducted a function at Thiruvananthapuram to formally release the Malayalam edition of Hortus Malabaricus. The book was released by the Governor of Kerala (also Chancellor of the University), at the function; where due recognition was not given to Manilal as author of the book, nor were arrangements in place to felicitate the author at the function. . The former Vice-Chancellor of University of Kerala who initiated the project, B. Ekbal, was also not invited to this function.

Kamlaksha Rama Naik, better known as K R Naik (Hindi: क़ रा नायक़) is an Indian industrial engineer. He founded D-Link Ltd. (India) in 1993. He has been in the IT Industry for 42 years and has played a key role in creating the IT networking market and the surrounding channel ecosystem in India. He pioneered several new businesses and distribution models as early as 1990, when IT was a nascent industry and the concept of an IT distribution channel was just conceived.

Early life

Naik was born in Karwar, Karnataka on 19 November 1947. He completed his schooling in Karwar and later shifted to Mumbai. Naik is a mechanical engineer with a P.G. Diploma in Industrial Engineering and Licenciate in Plastic Engineering. He earned a Business Management degree from the Jamnalal Bajaj Institute in Mumbai.


His first job at Mumbai was with Bradma, but soon after that he joined IBM India in 1970 starting as a Mainframe Peripheral Assembly Engineer. In 1977 he contributed significantly to the development of an indigenous line printer at the 'Big Blue' center. He worked to develop indigenous computer peripheral parts of plastic and metal until IBM closed its Indian operation in 1978. After IBM closed down, he joined ORG System Ltd. wherein he was one of the 6 team members who developed the first indigenous line printers with a speed of 1000+ line per minute.

In 1984, Naik founded Virtual Computer Pvt. Ltd., and was among the first to import a wave-soldering machine to manufacture printed circuit boards of PCs.

From 1990–91, Naik entered into networking products as a distributor of D-Link brand products. Within 3 years, he decided to start manufacturing of networking products in India as a joint venture with D-Link. Taking financial and tax advantages offered by the government of Goa, he shifted manufacturing operations from the Ansa Industrial Estate in Mumbai to Verna Electronic City, Goa. In 1994–95 he also started a passive networking-products company together with UK-based passive components company Sapphire UK Ltd. In 1994, he entered into a joint venture with D-Link Corporation Taiwan and helped constructing new buildings and importing SMT lines from Japan.

In 1995, Naik set out to create a completely new channel for D-Link products. Rather than going after large distributors he decided to put a regional distribution model in place—arguably the first in India among the IT channel.

Scientific career
Fields Mathematics

K. Ananda Rau (21 September 1893 – 22 January 1966) was an eminent Indian mathematician and a contemporary of Ramanujan. Though Rau was six years junior to Ramanujan, his mathematical trajectory, unlike Ramanujan's, was very much a conventional one and he had decided to pursue a career in mathematics well before Ramanujan's prowess became known.

Ananda Rau is seated on the high stool at the far left along with Ramanujan in the front chair

Ananda Rau was born in Madras on 21 September 1893. He attended the Hindu School in Triplicane, Madras and then Presidency College of the University of Madras. After a brilliant academic record, he sailed to England in 1914 only a few months after Ramanujan. After finishing his Mathematical Tripos from King's College, Cambridge, in 1916, he, like Ramanujan, came under the influence of G. H. Hardy, who guided and initiated him into active research. At Cambridge, Rau and Ramanujan became good friends. Moreover, Ramanujan's "most devoted friend" R. Ramachandra Rao, who was a District Collector, was Ananda Rau's relative. Ramachandra Rao, was responsible for mentoring Ramanujan on seeing his prowess in research, and provided financial aid, took care of his daily needs and got him a clerk's job at the Madras Port Trust. Though Ananda Rau met Ramanujan for the first time in England, he would have come to know of Ramanjuan through his relationship with Rao.

Ananda Rau returned to India in 1919 and was appointed as a professor of mathematics at Presidency College at the age of 26. Later, he served also as the Principal of the college and retired in 1948. His life was not without tragedy, as his wife died at a young age in 1928 and a daughter in 1940. He himself suffered various disabilities, including blindness in one eye, in his later years. He died on 22 January 1966, at the age of 72.

Academic work

As a student, Rau wrote an essay under Hardy's guidance that fetched him the coveted Smith Prize in 1917, following which he was also elected a fellow of King's College. Along with Hardy, Rau did a considerable amount of work on "Summability" and convergence properties of infinite series. In fact, a theorem named after Rau figures in Hardy's book. Rau published several papers, primarily in three fields: summability of series, theory of functions of a complex variable and sums of an even number of squares. Among the first papers he wrote after his return was on the subject of the Riemann zeta function, and the technique devised by Rau was found to have wide applicability in other problems of number theory.

Teaching influence

Ananda Rau taught several well-known mathematicians, including Subrahmanyan ChandrasekharK. S. ChandrasekharanS MinakshisundaramC T RajagopalC S Venkitaraman and M V Subbarao. His students regarded him as an inspiring teacher who emphasized that mathematics is an activity requiring immersion and dedication and is not for spectators. The story of Indian mathematics beyond Ramanujan begins with Rau and it is essentially Rau's students and descendants who constituted the Indian school of number theory.

Kaushal Kishore (1942–1999) was an Indian polymer chemist and head of the department of inorganic and physical Chemistry at the Indian Institute of Science (IISc). He was known for his researches on thermochemistry and combustion of polymers. and was an elected fellow of the National Academy of Sciences, IndiaIndian National Science Academy, and the Indian Academy of Sciences. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, in 1988, for his contributions to chemical sciences.

IISc - Main Building

Kaushal Kishore, born on the last day of 1942 in the Indian state of Uttar Pradesh, did his graduate studies in chemistry at Lucknow University and obtained his master's degree from the same institution before enrolling for doctoral studies at Deen Dayal Upadhyay Gorakhpur University where he studied under the guidance of R. P. Rastogi to secure a PhD for his thesis on mechanism of combustion of non-hypergolic propellants. His career started at Gorakhpur University as a teaching faculty but he moved to the Indian Institute of Science in 1974 where he rose in ranks to head the department of inorganic and physical chemistry from 1994. His early researches were on thermochemistry and combustion of polymers with focus on the kinetics and thermodynamics of combustion, particularly with solid propellants. These researches assisted him in discovering autopyrolysis, a term he coined for a phenomenon related to accelerated combustion caused by polyperoxides, details of which he published in one of his articles. He was credited with developing Flammability Index, a dimensionless quantity to assess the flammability of combustible materials. He also worked on plasticization and his studies have assisted in widening the understanding of plasticizers and flame-retardants containing phosphorus. He published several articles in peer-reviewed journals and the online repository of the Indian Academy of Sciences has listed 165 of them. He was associated with the Journal of Applied Polymer Science as a member of their editorial board and sat on a number of councils and committees.

Kishore lived in Bengaluru and it was here he died on 2 March 1999, the day of the Indian festival Holi, succumbing to a cardiac arrest at the age of 56.

Dr Kumar Bahuleyan
Home is where the heart is Kumar Bahuleyan’s two younger brothers and a sister were screaming with pain. He felt helpless as he looked at them. His father and mother did not know what to do. In the 1920s, in the village of Chemmanakary, 20 km from Kochi, there was no drinking water, electricity, schools, or sanitary facilities. “My siblings got sick by drinking polluted water,” says Bahuleyan. “And there was no doctor to cure them. They died of roundworm infestation. Even now, 80 years later, I can hear their screams in my head.”

Bahuleyan’s father, Kumaran, a subsistence farmer, belonged to the low-caste Ezhavas. As a child, Bahuleyan was pot-bellied, with a runny nose, and suffered from amoebiasis, chicken and small pox, scabies and typhoid. When Bahuleyan wanted to study in an English-medium school, his father was unable to pay the fees. So he joined the Malayalam government school.

One day, after Bahuleyan had completed his Class 7 final exams, he was walking with his father, in front of an English-medium school run by a Brahmin, Harihara Subramaniam Iyer.

“Kumaran, where are you going?” said Iyer. Kumaran said that he was trying to get admission for Bahuleyan in another school. Astonishingly, Iyer offered Bahuleyan a seat, even though the monthly fees were `3.50. Bahuleyan says, “It was the biggest break of my life.”

After his schooling, Bahuleyan went to UC College in Aluva and completed his science degree in 1949. By this time Bahuleyan’s aim had crystallised: he wanted to become a doctor. “My siblings had died of preventable diseases,” he says. “I wanted to use my expertise to cure the world.”

Thereafter, he secured admission to the Madras Medical College. Unfortunately, the capitation fees of `1,200 had to be paid. His maternal uncle, Padmanabhan, who was well off, sold off a piece of land and gave Bahuleyan the money. “With that sum I was able to attend the first-year classes,” says Bahuleyan. For the second year, Bahuleyean went to Subramaniam Iyer for help. And Iyer did an extraordinary thing. He pawned his wife’s jewellery and gave Bahuleyan `3,000. For the third year, Bahuleyan also did something extraordinary. He got himself engaged, with the help of his father, to the daughter of an affluent liquor dealer.

Consequently, Bahuleyan used the dowry money to pay the fees. But once he graduated, he broke off the engagement. “The girl’s father set too many conditions,” says Bahuleyan. His father was deeply offended, and never again spoke to his son.

Meanwhile, the state government sent Bahuleyan to do neuro-surgical training at the University of Edinburgh. He spent six years there and returned in 1964. The very next year, he was drafted into the army, during the India-Pakistan war, because the Armed Forces did not have a qualified neuro-surgeon. Following that, in 1968, he immigrated to the US, and finally settled in Buffalo, New York, in 1973.

Known for his extraordinary talent as a neurosurgeon, his career took off, and he made millions. “I was the right person at the right time at the right place with the right skills,” he says. Soon, he bought a large house, owned six Mercedes cars, a Cherokee 4 airplane, and a Honda 500 cc motorcycle. “It was my hedonistic days,” he says. “I threw wild parties and lived on the fast lane. I got everything money could buy, but it did not make me happy.”

Every now and then he would return to Chemmanakary and would observe that nothing had changed. In 1989, he set up the Bahuleyan Foundation and set aside $20 million for it. His first project was to set up a clinic catering to women and children. Later, Bahuleyan built new roads, improved sanitation facilities, and set up a potable water supply system. In 1996, Bahuleyan established the Indo-American Brain and Spine Hospital in the village. Today, it is a 220-bed super-speciality hospital and one of the premier institutes in south India. In 2004, he set up the Kalathil Lake Resort; the profits are used for charitable works. Apart from that, he also started a nursing as well as a physical therapy college.

On the personal front, he had an arranged marriage in 1958, but got divorced in 1968. One child, son Saju, lives in Chicago. His second marriage to a widow, Dr Indira Kartha, took place in 1985. And, today, at the age of 86, Bahuleyan continues to do surgeries. “By the grace of God, my hands are steady and my brain is fine,” he says. Bahuleyan divides his time between the USA, where his wife lives, and the hospital where he works 24/7.

And thus continues the ongoing saga of a most extraordinary Malayali.


Haunted by dying screams NRI doctor donates US$ 20 million to Kerala village Chemmanakary in Kottayam


CHEMMANAKARY, ONE of the typical Kerala villages in Kottayam district has had the fortune to have a Kumar Bahuleyan born there. Dr Bahuleyan, look up to the village as his own home and started transforming the village into a heaven by investing his hard earned American dollars into make a shape to the life of his counterparts in Kerala.

Bahuleyan, who belongs to the ‘untouchable community’ (read as Dalit), lived in the village seeing the poverty even though his father was a physician in the village. He saw his three siblings dying because of starvation. The family brought up the two remaining in the poor family and Bahuleyan who was good in education, fought to survive and go to the school. He fought, disease and hunger every step of the way and his brilliancy helped him to get through the Kerala government’s scholarship while studying. He stood first in while education and it helped him to acquire a medical degree. Dr Bahuleyan was an eternal optimist, in his own words.

After graduating in medical science, the Kerala government taking into account his ability to circumvent sent him to the United Kingdom for for neurosurgical training as the state did not have a neurosurgeon at that time. When the doctor returned home the military picked him up for the forces, which did not have a qualified neurosurgeon, during the time of Chinese aggression.

However, the Keralites does not have the fortune to get served by the eminent doctor or it may be the doctors ‘fortune’ that the Kerala government did not have a place for him. A fresh man had filled his place, when he returned. The bureaucratic red tape followed doctor and the qualified surgeon had to sit at home ideally. Waiting made doctor to flee his mother country to Onatario, Canada in the United Kingdom seeking an opportunity their. He found a right place in Buffalo, where for the first time in his life he achieved economic and professional security.

However, doctor never forgot his native place, Chemmanakary. He kept visiting the village regularly whenever he got a short vacation. Whenever he visited his native village he found the sad state of his village is as it is even after fifty years of much celebrated Independence. The doctor found that his native still did not have potable drinking water, sanitation, electricity, roads and health centers. The condition of sanitation in the village was very poor and he noticed that even well settled community in his village never bothered about the contamination, which was lacking people’s awareness.

The doctor started acting accordingly. He never tried to blame the authorities or the people living around him. Instead, the energetic doctor took an oath to set up a beautiful and clean village. In 1989, doctor established a not-for-profit private organization to bring basic health care to Kerala villages. The doctor put in around Rs 10 crore during two three years, and his attempt was to come back to his village and do some community work.

The Bahuleyan Charitable Foundation, founded by Dr Kumar Bahuleyna, began with a health survey to pick a target area. It chose an area comprising 17 sq. miles with a population of 66,356.The foundation plunged into a latrine construction programme in this area where 5009 of the 18,362 houses did not have latrines.So far 619 latrinees meeting WHO standards and costing Rs.4,000 each have been built. "The people initially had no clue what to do with a latrine and started using it as a store room,” says Bahuleyan.

In 1993 the foundation built a small clinic in the village to treat pregnant women and children. Demand was so high in spite of poor accessibility ( there were no roads leading to the clinic),that the centre was soon upgraded and moved to Vaikom town. The foundation also spent Rs.50 lakh to construct a 6km road to the main highway and subsidiary roads to link the clinic.

The Vaikom wing of The Indo- American Hospital opened in 1995 with 30 beds."It was named to highlight the fact that it is built with the money I earned in the U.S and to acknowledge the American taxpayer’s contribution,” explained the doctor.

But with most of the patients being poor the hospital was making little by way of revenue and its very existence was threatened . "I started this whole project out of my sentiments, with no planning,” said Bahuleyan.” " However I realized I had to do something revenue generating to make it viable.”

Today the Indo American Speciality Hospital for Neuro Surgery is a supreme blend of American Technology occupied with Indian tradition of selfless service to humanity. This super speciality hospital provides all facilities as available in any of the finest humanity. This super speciality hospital provides all facilities as available in any of the finest hospitals in Europe or the US. The hospital comes along with a posh backwater resort, Kalathil Health Resort that caters to the aspirations of the national and international patients and tourists. The revenue surplus and the proceeds from the resort would help to augment and expand the reach of charity of Indo-American Hospital.

The Latest Take from the Press…

EIGHTY-ONE-YEAR-OLD KUMAR Bahuleyan, a neurosurgeon, who once led a lavish lifestyle that included moving around in a Rolls Royce and five Mercedes, besides an aeroplane, has used the money to build a hospital specialising in neurosurgery, a health clinic and a spa in Chemmanakary in Kerala's Kottayam District. A Dalit based in Buffalo, New York, for the last 34 years, has given 20 million dollars to his village in Kerala.

Bahuleyan said that the desire to do something for his native place germinated between 1982 and 1987, when he visited the area, and found that nothing had changed. He said that he felt like returning something to the village, which had taught him and made him something in life.

Bahuleyan says he lost two younger brothers and a sister to water-borne disease in 1930s, and even today he says he is haunted by their dying screams. As a 'untouchable', Bahuleyan had to take a circuitous route to school because he wasn't allowed to pass a Hindu temple. A brilliant student, he succeeded in joining a medical college in Madras. From their, he proceeded to Edinburgh for six years of neurosurgical training before eturning home.

Unfortunately, there was no vacancy for a neurosurgeon in those days, and Bahuleyan left for Kingston and then Albany Medical College, before coming to Buffalo in 1973 to work with noted American neurosurgeon Dr John Zoll.

During his 26-year career, Bahuleyan served as a clinical associate professor in neurosurgery at the University at Buffalo before retiring in 1999 as a multi-millionaire.

In 1989, he set up the Bahuleyan Charitable Foundation, which built a small clinic in India for young children and pregnant women in 1993 in south India. Bahuleyan's foundation also built the Indo-American Hospital Brain and Spine Centre in 1996, starting with 80 beds.

The foundation opened the Kalathil Health Resorts, offering luxury rooms, health spas and exercise rooms in 2004.

Bahuleyan's latest venture -- East India Seven Seas Sailing Company, plans to invite applications from Americans willing to spend a few weeks in India, to volunteer in Bahuleyan's hospital and to teach sailing.

Bahuleyan lives with his wife, pathologist Indira Kartha. He spends six months of the year in America, and rest in India, looking after the work of his foundation.

Dr. Kumar Bahuleyan – Born Extremely Poor, Became Rich and is Donating All to Help Others in NeedI discarded Mercedes Benz for a Bicycle like a small kid discarding old toy for new one”— Dr. Kumar Bahuleyan

“Who dies rich dies disgraced.” said Andrew Carnegie and Lord Buddha said— “To conquer oneself is a greater task than conquering others.” Here is an inspiring story from Kalam Fan Club about a philanthropist and an Indian-American Neurosurgeon whose life has been a classic example of being a true practitioner of the above two quotes. The story of Dr. Kumar Bahuleyan is two folded; He was born in rags of a remote village in Kerala, India and succeeded to be an iconic neuro surgeon to practice in Buffalo, the USA with all materialistic comforts under the sun in his possession, thus providing a rags-to-rich success story. But his inner drive to help the poor masses in his motherland with a charitable super specialty hospital by donating all his earnings gives silver-lining to his success story. The fact that he has ensured that his name doesn’t get portrayed anywhere in his charitable work manifold his philanthropic mission. A doctor who was born in a poor village background without proper sanitation and drinking water and grew up to own Mercedes Benz, Royal Royce, and Airplane and donated 20 million $ for the upliftment of his native village is a remarkable achievement on any scale.

Dire Childhood Days & Education

Dr. Kumar was born in a remote village called Chemmanakary in Kottayam district of Kerala. His child hood days (the 1930s) were so awful that all his siblings suffered from epidemics and as the eldest of four children he had to witness the death of his three siblings who were not even eight years old. As he belonged to untouchable caste schooling was also not easy in those days. He had to take a roundabout route to school as he was not allowed to commute on the road with the temple. Fortunately, this boy’s learning ability was identified by a headmaster of a school belonging to lower caste school. This headmaster readily agreed to teach this boy for free and thus the trauma of going to a far away school ended for Kumar. Most interestingly in those days of intense practice of untouchability, Mr. Harihara Subramaniam Iyer an upper-class Brahmin offered a seat for this lower caste boy in his English medium high school. This happened to be a turning point in his education. Further, he got the opportunity to study para medical in a Christian missionary school. Later he joined medical college of Madras (Chennai). Dr. Kumar always acknowledges the scholarships provided by the Govt. for his education and accepts it would have been impossible for him to complete his education. His life was completely poverty-ridden, and he didn’t have a pair of shoes to go to medical college. He often claims that he is an eternal optimist.

Higher education in Scotland

The Kerala Govt. having recognized his abilities funded him to pursue neurosurgery in Scotland as no neurosurgery department was available back home. On his return back home, in 1965 he was posted in Indian Army during India-Pakistan war to support army personnel as a specialist neurosurgeon. But, after the warfare Govt. failed to accommodate him in any neuro surgeon post he was left jobless unable to break the bureaucratic red-tape-ism prevailing in the country.

Career Abroad
Due to the pathetic condition back home, he started applying for prospects overseas and immigrated to Ontario, Canada, seeking employment. Finally, he settled at Buffalo, USA and for the first time in his life sensed economic security. His marathon 26 years of private practice had a great beginning with offices at Linwood and Kenmore avenues cum main streets. He even served as a clinical associate professor at the University of Buffalo before retiring in the year 1999. Dr. Kumar Bhauleyan had made up for what he had lost in his childhood by getting into buying spree and enriched himself with all material comforts his mind prompted him to possess. Unfortunately, Dr. Bahuleyan’s first marriage didn’t click and he got married to Dr. Indira a widow in the year 1985. He was happily leading a life with his wife Dr. Indira kartha, who is pathologist by profession. But an inner feeling of emptiness started popping up in Dr. Kumar’s mind and he started probing life beyond material comforts of a multi-millionaire.

Turning Point for Charity Spree

Dr. Kumar Bhuleyan was back in the home for vacation and could witness the country have not changed drastically. He witnessed a scene of a lonely young mother standing on the roadside with a 3-year-old pot-bellied child with running nose and scabies all over the body. This poverty ridden parent and child recalled the nightmares Dr. Kumar himself had underwent after the tragic death of his siblings in childhood days. He realized the extremity of life that he is a successful icon in America living in material comforts and an innocent child without having any prejudice of caste, creed, and status suffering in his motherland. The enlightenment Dr. Kumar was badly looking for had struck, and he decided to spend six months in a year in India serving the poor in need of medical attention and spend another six months in the USA. He took the initiative to build septic tanks for enabling people to use toilets; around 3000 toilets were in place. He initiated construction of new roads, and even 25 to 30 housing units were built and to ice the cake he built the most needed charitable hospital.

Here is the path trod by Dr. Kumar in serving the society:

In 1989, he established non-profit-organization Bahuleyan Charitable Foundation to bring basic health care to Kerala villages by pouring ten crores of rupees from his savings to the Foundation

The foundation plunged into toilet construction program where a one-third of houses did not have sanitation, approximately 619 latrines meeting WHO standards were constructed

In 1993 the foundation built a small clinic in the village to treat pregnant women and children. The demand for treatment was so high in spite of bad road conditions, Dr. Kumar took a new initiative to build a 6 Km road to establish connectivity to the clinic by spending 50 lakh rupees.
In 1995 the vaikom wing of the Indo-American Hospital was started with 30 beds. The hospital was named so to acknowledge the American tax payer’s contribution in the fund used

To ensure sustainability of this charitable foundation, Kumar took help of consultants and came up with idea of a super-speciality hospital to fetch revenue from affordable people, thus in 1996 a super-speciality neurosurgery hospital got incepted

Kumar is also serving village communities by providing them with innovative sustainable agricultural practices

To enhance the availability of trained medical practitioners he has plans to set up nursing training and medical technicians training institutesToday at the age of 86, Dr. Kumar Bahuleyan is healthy to conduct surgeries, and he humorously says—“By the grace of God, my hands are steady and my brain is fine,” and while in India he stays at hospital premises. Interesting fact about Dr. Bahuleyan’s saga of service is as soon as he shifted his area of operation to Kerala villages; He discarded his Mercedes Benz and bought a bicycle in exchange. He is quoted to have said that “This behaviour was similar to that of a school going kid that discards old toys for the new one!”

Kalam Fan Club is proud of this 86 year old young boy who is serving the community relentlessly.

Louis Pasteur

Louis Pasteur was born on 27 December 1822 in a labor family in a place called Dole, France. His leather businessmen were ordinary. His father's wish was that his son become a great man by studying.

Louis Pasteur was born on 27 December 1822 in a labor family in a place called Dole, France. His leather businessmen were ordinary. His father's wish was that his son become a great man by studying.

They also wanted to bear the burden of debt for his studies. While working with his father, Louis took admission in a school in Arboi to fulfill his father's wish, but the learning taught by the teachers was beyond his grasp.

He was teased as Mandabuddhi and Buddha. Unhappy at the neglect of the teachers, Louis gave up schooling, but he thought of doing something so that the whole world would respect him as an intelligent, not a Buddha.

After being forced by his father, he went to Paris for higher education and started studying at a college in Vaisako. His special interest was in chemistry. He was particularly influenced by Dr. Duma, a scholar of chemistry.

At the age of 26, Pasteur started teaching physics instead of chemistry, receiving a degree from Econnarmel College. Overcoming obstacles, he became the chairman of the science department. After accepting this post, he started research work.

After finishing college, he started working in a chemical school to achieve his goal. Here you studied crystals and also did some important research. You started getting good fame in the form of chemicals from them.

In the year 1896. In France, the Minister of Education appointed you to teach physics in the school of Dijon. A year later, he was made a substitute professor of chemistry at the University of Strasbourg. The secret of this advancement was that the university president had a girl whose name was mine. I was a beautiful teenager with beautiful hair. You met him Mary's untouched lavana has gone home in your heart. Only a week after the meeting, you proposed marriage to Mary. Mary turned down your offer. But Louis Pasteur was a good scientist. Endurance was in you. You continued to try despite Mary's refusal. After one year, you got success in your wish fulfillment. Mary accepted to be your wife.

After marriage, your interest started moving from chemistry to biology. This is the science of organisms. The university is in the middle of the grape growing region of France. One day a group of wine makers came to meet Louis Pasteur one day. He asked you that our liquor turns sour every year. What is the reason for this?

Louis Pasteur received chemistry education in Paris. From 1873, Pasteur began to revise on chemistry. From 1857, that is, at the age of 32, he became the Dean of the University Ong Lily. They began to focus on the study of compositions of joint or original values. He laid the basic principles in revision of biochemistry. It was an old belief that micro-organisms are self-generated, they are created by themselves. Pasteur's amendment uprooted this thinking. Pasteur overthrew this thinking by constructing animals or micro-organisms into rotting flora or fauna.

After some time Pasteur turned his attention to another area. In France, the wine and beer industry was disturbed by an objection in the year 17.

In this country, the main business of alcohol production, liquor used to get spoiled after filling in bottles. Because of this, this business was a big fraud. Louis Pasteur found a solution for this. Heating the bottles filled with alcohol to a temperature of 55 degrees Celsius, proved that the pollutants are removed from the wine and the wine started to last for a long time.

Pasteur suspected that air also contained bacteria. He conducted an experiment to investigate his suspicions. He took a little cotton and put it in water and boiled it well, So that all the bacteria hidden in it die. Then, remove the cotton and put it in the air and after a while put it back in the same water. Bacteria started appearing again in water. Remember that all this work was being done with the help of microcosm. From this experiment, it appeared that there are bacteria in the air. Pasteur conducted another experiment. He thought of a way in which cold air in a soup filled with a vessel would go on continuously but the bacteria of the air did not reach. He realized that bacteria stick to dust particles in the air. He made a special kind of flask. Pasteur filled this flask with half of the soup and then boiled the soup. Let the steam out of the twisted tube for a long time. In this way all the bacteria in the soup and tube died. Then he allowed the soup to cool down. The folded hose of the flask was also kept open so that air could enter. The wind could reach the soup,


Pasteurization is the method in which microorganisms such as bacteria, fungi, viruses, etc. are destroyed by heating liquids. It is named after the Persian scientist Louis Pasteur. Louis Pasteur first used pasteurization on 20 April 1862.

Cherpu, Kerala
Nationality Indian
Scientific career

Mamannamana Vijayan (born 16 October 1941, Cherpu, Kerala[1]) is an Indian structural biologist. His main area of research is protein structures. His contributions have been towards the structure and carbohydrate specificity of lectins and protein hydration. He has also contributed towards the area of structure and interactions of mycobacterial proteins and supramolecular association with reference to chemical evolution and origin of life. Vijayan did biological macromolecular crystallography in India.

He was awarded Padma Shri by the President of India in 2004. He was the President of the Indian National Science Academy from 2007–2010. Currently, he is DAE Homi Bhabha Professor at the Indian Institute of Science.


Vijayan obtained his Masters of Science degree in 1963 from Allahabad University. Thereafter, he received his Doctorate degree in X-ray crystallography from the Indian Institute of Science in 1967. During 1968–71, he was a post-doctoral fellow in Professor Dorothy Hodgkin’s research group at University of Oxford. During that period, he studied x-ray diffraction data for insulin crystals.

Contribution in structural biology

Vijayan's students and postdocs have dealt with four of the five structural classes of plant lectins. They have studied in detail lectins from peanut, winged bean (basic and acidic), jackfruit (jacalin and artocarpin), garlic, banana and snake gourd. The work on lectins demonstrated the need for considering open quaternary structures when dealing with multimeric proteins[5] and the variability in the quaternary association of legume lectins. and lectins with the β-prism I fold. His group established β-prism I fold as a lectin fold. They explained the roles of water-bridges, post-translational modification, oligomerisation and variation in loop length as strategies for generating ligand specificity. Their studies provided insights into the structural basis of carbohydrate specificity and the biological implications of this specificity. Using an approach involving water-mediated transformations, Vijayan's research determined the nature of the flexibility in lysozyme and ribonuclease A and identified the invariant features in their hydration shells. His research also demonstrated the presence of ensembles of relaxed and tense states of haemoglobin. and water-mediated loop movement in β-lactoglobulin. His studies have provided insights into the relationship among hydration, molecular mobility and protein action.

Vijayan organised a national programme on the structural biology of microbial pathogens. His research in the area has been concerned with mycobacterial, particularly tuberculosis, related proteins. The specific systems studied by him include RecA, RuvA, uracil DNA glycosylase, single stranded DNA binding protein, ribosome recycling factor, peptidyl tRNA hydrolase, pantothenate kinase and DNA binding protein in stationary phase cells. He has elucidated the specific structural features of these proteins in mycobacteria, which, among other things, have opened up avenues for structure-based inhibitor design, with the eventual objective of drug development.

Vijayan's research have determined the molecular recognition and aggregation patterns involving amino acids and peptides using an approach based on molecular complexes. This has implications to chemical evolution and origins of life. His other contributions pertain to the structure and interactions of non-steroidal anti-inflammatory analgesics, ionophores and related compounds, side chain conformation in proteins and additional binding sites in lysozyme.

Vijayan has published more than 260 peer reviewed research articles and has guided 38 research students and 20 postdoctoral fellows.

Professional life

After completing his postdoctoral research at the University of Oxford, he returned to India in 1971 and joined the Molecular Biophyiscs Unit at the Indian Institute of Science (IISc). He has served in various capacities such as Professor, Chairman of Molecular Biophysics Unit, Chairman of Division of Biological Sciences among others. During 2000–2004 he was Associate Director of IISc.[1] He has continued to work at the Institute as a DBT Distinguished Biotechnologist and subsequently as a DAE Homi Bhabha Professor.

Prof. Vijayan's course on fundamentals in crystallography was extremely popular with students at the Indian Institute of Science. His unique approach of interlacing historical developments in the field with conceptual aspects made the course vibrant and energetic.

Role in international and national organisations

Vijayan is a member of the International Union of Crystallography (IUCr), the International Union of Pure & Applied Biophysics (IUPAB), the International Council for Science (ICSU), the Inter Academy Panel (IAP) and the InterAcademy Council (IAC). He is a former president of the Asian Crystallographic Association. He has been involved in the activities of the science departments and agencies of the Government of India and different scientific institutions in the country. He is the Founder President of the Indian Crystallographic Association and has served as the President of the Indian Biophysical Society and the President of the Indian National Science Academy (2007–2010).

Awards and recognitions

Vijayan is a Fellow of the three science academies of India[1] and the Academy of Sciences for the Developing World (TWAS). He has won the Shanti Swarup Bhatnagar Prize, GN Ramachandran Medal by INSA, Alumni Award Excell.

University of Madras Entrance Arch at Chepauk Campus

Mushi Santappa was born on 2 October 1923 in Jonnagiri village in the south Indian state of Andhra Pradesh to Arikeri Basappa-Rajoli couple and graduated in chemistry from the University of Madras in 1943. His master's degree was from Banaras Hindu University in 1946 after which he secured a PhD from the University of London on a Government of India scholarship in 1949, mentored by R. W. West. Staying back in the UK, he obtained another PhD in 1951 from Manchester University, working under the guidance of Meredith Gwynne Evans, a Fellow of the Royal Society; his thesis was based on the physical chemistry of high polymers. Returning to India, he joined the University of Madras as a reader of physical chemistry in 1952 and in 1958, he was transferred to the Madurai Extension Centre (present-day Madurai Kamaraj University) as a professor. He returned to Chennai in 1963 as the head of the department of physical chemistry. Serving as a UGC Senior Professor at the university from 1966 onward, he also worked as a director at Central Leather Research Institute (CLRI) from 1972. In 1979, he was appointed as the vice chancellor of Sri Venkateswara UniversityTirupati and on expiry of his tenure in 1980, he returned to Chennai and took up the assignment as the vice chancellor of the University of Madras in 1981 where he stayed till 1984.[2] While working as the UGC professor, he co-founded Avanti Leather Limited, a public limited company involved in the manufacture and export of leather products, in 1976.

Santappa was married to Lakshmi Devi and the couple has three daughters and two sons. He died on 26 February 2017, in Chennai, at the age of 93.


Santappa's early researches during his doctoral studies were related to vinyl monomers.4 and its free radical polymerization using light but later, he shifted his focus to the study of kinetics of vinyl polymerization during his stint at the laboratory of Meredith Gwynne Evans. Through these studies, he propounded that vinyl monomers could be polymerized using photo polymerization. He also demonstrated the synthesis of graft copolymers by simple chain transfer process and also studied oxidation of a number of organic substrates.

His researches have been published in over 350 articles and he guided 59 research scholars on the doctoral studies. Moreover, he published a comprehensive text on the State of the Art in Polymer Science and Engineering in India. Together with Santi K. Palit, a known chemist, he promoted research in polymer science at the Indian Association for the Cultivation of Science and was one of the organizers of the International Symposium on Polymers, under the aegis of the International Union of Pure and Applied Chemistry (IUPAC), held in Chennai in 1983.He served as the chair of the Science and Society project of the Department of Science and Technology and has been an adviser to the Tamil Nadu Pollution Control Board.

Mangalore, India
Occupation Writer, historian
Nationality Indian
Genre Genealogy

Michael Lobo (born 12 September 1953) is an Indian scientist, writer, and genealogist. He is the author of three self-published books on the Catholic community in Mangalore, India.

Early life and education

Michael Lobo was born in MangaloreIndia to Maisie Lobo (née Fernandes) and Camillo Lobo, both of Mangalorean Catholic descent. He belongs to the Bejai branch of the Lobo-Prabhu clan, that has its roots in the Makhale suburb of Kulshekar, Mangalore. Lobo's father was a British army soldier who served during World War II. He studied at Montfort High School in Yercaud, Tamil Nadu, and graduated from St. Aloysius College. In 1975, he was one of the "National-A" level chess players in the country, which put him among India's top 20 chess players. In 1982, he obtained a PhD from IISc Bangalore, with a degree in Applied Mathematics. His doctoral thesis on Transonic Aerodynamics earned him the "Young Scientist Award" from the Indian National Science Academy (INSA). In 1982, he earned a PhD in aerodynamics mathematics from the Indian Institute of Science, Bangalore, receiving the 1983 Young Scientist Award from Indian National Science Academy.

Academics (1984–1993)

In 1984, Lobo moved to England where he entered the Cranfield Institute of Technology on a Commonwealth Scholarship, eventually becoming a faculty member. While employed there, Lobo authored papers on Computational Fluid Dynamics (CFD), including Time Marching – A Step-by-step Guide to a Flow Solver (Ashgate Press, 1997). In his spare time he compiled a 1000-page dictionary of English words derived from Classical Greek and wrote a book on the origins of popular Rock'n'roll songs, but neither was published. He returned to Mangalore in 1993, because of "personal crises".

Genealogy (from 1994 onwards)

Lobo's interest in genealogy began in 1992, upon his discovery of an antique baptismal register belonging to the period 1810–80 at Milagres Church. While browsing through this register, he discovered the birth record of his great-grandfather, Anthony Peter Lobo. The record traced his parentage to Lawrence Lobo (a Munsiff and eminent member of the 19th century Mangalorean Catholic community) and Ignatia Tellis. He then subsequently scoured the register to locate the birth records of the other children of Lawrence and Ignatia.

This register became the nucleus of his first genealogical project—a biographical compilation of all the descendants of Lawrence Lobo (through both male and female lines of descent). From late 1992 to late 1993, Lobo began working during his spare time on this project, and by the end of 1993, had completed the first draft of his genealogical work on the Lobo-Prabhus of Makhale and their related families. After the end of his contract at the Cranfield Institute of Technology, rather than renew his contract or pursue a contract elsewhere, Lobo decided to give up his mathematical career and pursue a personal project to write the history and genealogy of the Mangalorean Catholic families.

He moved to Mangalore in 1994, and settled down in his family manor "Camelot Residency" on Bijai church road. During 1994–95, Lobo was involved, on a full-time basis, on a research project on the history and genealogy of the Catholic community of Mangalore. He copied almost every 19th century baptismal, marriage and death record he could locate at Rosario Cathedral and Milagres Church, cataloguing them according to surnames. Lobo initially experienced difficulties in the project since only the baptismal registers were maintained in reasonably good condition, while large sections of the marriage and death registers were missing, and it was not feasible to build the genealogy of any family on the basis of baptismal records alone.

However, he had access to other sources of information on the major families, such as the Vas-Naiks of Falnir (the first published work on the genealogy of a Mangalorean Catholic family), Mascarenhas-Prabhus of Falnir, and the Fernandes-Prabhus of Tonse. There were also unpublished genealogies of various other families, most of them written by Mangalorean genealogists Rao Saheb Francis Xavier Lobo and Marian Saldanha. The project took shape as A Genealogical Encyclopaedia of Mangalorean Catholic Families. Lobo also conducted and still conducts personal interviews with many Mangalorean Catholics, who have settled in BangaloreMumbaiChennaiDelhi and various other parts of India and abroad. This work is expected to be about 8 to 10 volumes and as of March 2011, had already crossed 7000 pages.

Although his work is unfinished, Lobo has self-published three offshoots on the subject: Mangaloreans Worldwide – An International Directory (1999), Distinguished Mangalorean Catholics 1800–2000 – A Historico-Biographical Survey of the Mangalorean Catholic Community (2000), and The Mangalorean Catholic Community – A Professional History / Directory (2002). His encyclopaedia covers more than a thousand families and is being continually updated with names and records of new families.[3] He claims that the Mangalorean Catholic community has the distinction of being the only community in the world to possess its own genealogical encyclopaedia.

Lobo has also authored two books on music entitled A Hundred Pages of Classics, Opera and Popular Instrumental Pieces – A Thousand Pages of Songs with Historical Notes and its companion edition Popular Music – A Historical and Thematic Analysis, both of which were released in 2011.

Maurice Ralph Hilleman (August 30, 1919 – April 11, 2005) was a leading American microbiologist who specialized in vaccinology and developed over 40 vaccines, an unparalleled record of productivity. According to one estimate, his vaccines save nearly 8 million lives each year. Many have described him as one of the most influential vaccinologists of all time.

Of the 14 vaccines routinely recommended in current American vaccine schedules, Hilleman and his team developed eight: those for measlesmumpshepatitis Ahepatitis BchickenpoxNeisseria meningitidisStreptococcus pneumoniae and Haemophilus influenzae bacteria. During the "1957-1958 Asian flu pandemic", his vaccine is believed to have saved hundreds of thousands of lives. He also played a role in the discovery of antigenic shift and drift, the cold-producing adenoviruses, the hepatitis viruses, and the potentially cancer-causing virus SV40.


Early life and education

Hilleman was born on a farm near the high plains town of Miles City, Montana. His parents were Anna (Uelsmann) and Gustav Hillemann, and he was their eighth child. His twin sister died when he was born, and his mother died two days later. He was raised in the nearby household of his uncle, Robert Hilleman, and worked in his youth on the family farm. He credited much of his success to his work with chickens as a boy; since the 1930s, fertile chicken eggs had often been used to grow viruses for vaccines.

His family belonged to the Lutheran Church–Missouri Synod. When he was in the eighth grade, he discovered Charles Darwin, and was caught reading On the Origin of Species in church. Later in life, he rejected religion. Due to lack of money, he almost failed to attend college. His eldest brother interceded, and Hilleman graduated first in his class in 1941 from Montana State University with family help and scholarships. He won a fellowship to the University of Chicago and received his doctoral degree in microbiology in 1944. His doctoral thesis was on chlamydia infections, which were then thought to be caused by a virus. Hilleman showed that these infections were, in fact, caused by a species of bacterium, Chlamydia trachomatis, that grows only inside of cells.


After joining E.R. Squibb & Sons (now Bristol-Myers Squibb), Hilleman developed a vaccine against Japanese B encephalitis, a disease that threatened American troops in the Pacific Ocean theater of World War II. As chief of the Department of Respiratory Diseases at Army Medical Center (now the Walter Reed Army Institute of Research) from 1948 to 1957, Hilleman discovered the genetic changes that occur when the influenza virus mutates, known as antigenic shift and antigenic drift, which he theorized would mean that a yearly influenza vaccination would be required.

In 1957, Hilleman joined Merck & Co. (Kenilworth, New Jersey), as head of its new virus and cell biology research department in West Point, Pennsylvania. It was while with Merck that Hilleman developed most of the forty experimental and licensed animal and human vaccines with which he is credited, working both at the laboratory bench as well as providing scientific leadership.

Hilleman served on numerous national and international advisory boards and committees, academic, governmental and private, including the National Institutes of Health's Office of AIDS Research Program Evaluation and the Advisory Committee on Immunization Practices of the National Immunization Program.

Asian flu pandemic

Hilleman was among the first to recognize that a 1957 outbreak of influenza in Hong Kong could become a huge pandemic. Working on a hunch, after nine 14-hour days he and a colleague found that it was a new strain of flu that could kill millions. Forty million doses of vaccines were prepared and distributed. Although 69,000 Americans died, the pandemic could have resulted in many more deaths in the United States. Hilleman was awarded the Distinguished Service Medal from the American military for his work. His vaccine is believed to have saved hundreds of thousands of lives.

In 1968, during the Hong Kong flu pandemic, Hilleman and his team also played a key role in developing a vaccine, and nine million doses became available in 4 months.


Hilleman was one of the early vaccine pioneers to warn about the possibility that simian viruses might contaminate vaccines. The best-known of these viruses became SV40, a viral contaminant of the polio vaccine, whose discovery led to the recall of Salk's vaccine in 1961 and its replacement with Albert Sabin's oral vaccine. The contamination actually occurred in both vaccines at very low levels, but because the oral vaccine was ingested rather than injected, it did not result in infections or any harm.

Mumps vaccine

In 1963, his daughter Jeryl Lynn came down with the mumps. He cultivated material from her, and used it as the basis of a mumps vaccine. The Jeryl Lynn strain of the mumps vaccine is still used today. The strain is currently used in the trivalent (measles, mumps and rubella) MMR vaccine that he also developed, the first vaccine ever approved incorporating multiple live virus strains. Like many other vaccines and medications of that time period, the vaccine was initially tested in children with intellectual disabilities who lived in group homes—this was because, given the poor hygiene and cramped quarters of their accommodations, they were at much higher risk of infectious disease.

Hepatitis B vaccine

He and his group invented a vaccine for hepatitis B by treating blood serum with pepsinurea and formaldehyde. This was licensed in 1981, but withdrawn in 1986 in the United States when it was replaced by a vaccine that was produced in yeast. This vaccine is still in use today. By 2003, 150 countries were using it and the incidence of the disease in the United States in young people had decreased by 95%. Hilleman considered his work on this vaccine to be his single greatest achievement. Liver transplant pioneer Thomas Starzl said "...controlling the hepatitis B virus scourge ranks as one of the most outstanding contributions to human health of the twentieth century...Maurice removed one of the most important obstacles to the field of organ transplantation".

Later work and life

In his later life, Hilleman was an adviser to the World Health Organization. He retired as senior vice president of the Merck Research Labs in 1984 at the mandatory retirement age of 65. He then directed the newly created Merck Institute for Vaccinology where he worked for the next twenty years.

At the time of his death in Philadelphia on April 11, 2005, at the age of 85, Hilleman was Adjunct Professor of Pediatrics at the University of Pennsylvania in Philadelphia.

Method and personality

Hilleman was a forceful man yet at the same time, modest in his claims. None of his vaccines or discoveries are named after him. He ran his laboratory like a military unit, and he was the one in command. For a time, he kept a row of "shrunken heads" (actually fakes made by one of his children) in his office as trophies that represented each of his fired employees. He used profanity and tirades freely to drive his arguments home, and once, famously, refused to attend a mandatory "charm school" course intended to make Merck middle managers more civil. His subordinates were fiercely loyal to him.: 128–131 

Awards and honors

Hilleman was an elected member of the National Academy of Science, the Institute of Medicine, the American Academy of Arts and Sciences, and the American Philosophical Society. In 1988, President Ronald Reagan presented him with the National Medal of Science, the nation's highest scientific honor. He received the Prince Mahidol Award from the King of Thailand for the advancement of public health, as well as a special lifetime achievement award from the World Health Organization, the Mary Woodard Lasker Award for Public Service and the Sabin Gold Medal and Lifetime Achievement Awards. In 1975, Hilleman received the Golden Plate Award of the American Academy of Achievement.


In March 2005, the University of Pennsylvania School of Medicine's Department of Pediatrics and The Children's Hospital of Philadelphia, in collaboration with The Merck Company Foundation, announced the creation of The Maurice R. Hilleman Chair in Vaccinology.

Robert Gallo, co-discoverer of HIV (the virus that causes AIDS), said in 2005: "If I had to name a person who has done more for the benefit of human health, with less recognition than anyone else, it would be Maurice Hilleman. Maurice should be recognized as the most successful vaccinologist in history."

In 2005, after Hilleman's death Ralph Nader wrote, "Yet almost no one knew about him, saw him on television, or read about him in newspapers or magazines. His anonymity, in comparison with MadonnaMichael JacksonJose Canseco, or an assortment of grade B actors, tells something about our society's and media's concepts of celebrity; much less of the heroic."

In 2005, Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, said that Hilleman's contributions were “the best kept secret among the lay public. If you look at the whole field of vaccinology, nobody was more influential. In addition, Fauci said that "Hilleman is one of the true giants of science, medicine and public health in the 20th century. One can say without hyperbole that Maurice has changed the world."

In 2007, Paul Offit published a biography of Hilleman, entitled Vaccinated: One Man's Quest to Defeat the World's Deadliest Diseases.

In 2007, Anthony S. Fauci wrote in a biographical memoir of Hilleman:

Maurice was perhaps the single most influential public health figure of the twentieth century, if one considers the millions of lives saved and the countless people who were spared suffering because of his work. Over the course of his career, Maurice and his colleagues developed more than forty vaccines. Of the fourteen vaccines currently recommended in the United States, Maurice developed eight.

In 2008, Merck named its Maurice R. Hilleman Center for Vaccine Manufacturing, in Durham, North Carolina, in memory of Hilleman.

In 2016, a documentary film titled Hilleman: A Perilous Quest to Save the World's Children, chronicling Hilleman's life and career, was released by Medical History Pictures, Inc.

In 2016, Montana State University dedicated a series of scholarships in memory of its alumnus Hilleman, called the Hilleman Scholars Program, for incoming students who "commit to work at their education beyond ordinary expectations and help future scholars that come after them."

Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indian astrophysicist who developed the Saha ionization equation, used to describe chemical and physical conditions in stars. His work allowed astronomers to accurately relate the spectral classes of stars to their actual temperatures. He was elected to the Parliament of India in 1952.


Meghnad Saha was born in 1893 in Shaoratoli, a village near Dhaka, in the former Bengal Presidency of British India (in present-day Bangladesh). Son of Jagannath Saha (a grocer) and Smt. Bhubneshwari Devi, Meghnad struggled to rise in life. During his early schooling he was forced to leave Dhaka Collegiate School because he participated in the Swadeshi movement. He earned his Indian School Certificate from Dhaka College. He was also a student at the Presidency College, Kolkata and Rajabazar Science College CU; a professor at Allahabad University from 1923 to 1938, and thereafter a professor and Dean of the Faculty of Science at the University of Calcutta until his death in 1956. He became Fellow of the Royal Society in 1927. He was president of the 21st session of the Indian Science Congress in 1934.

Amongst Saha's classmates were Satyendra Nath BoseJnan Ghosh and Jnanendra Nath Mukherjee. In his later life he was close to Amiya Charan Banerjee. Saha was an atheist.

Saha died on 16 February 1956 of a cardiac arrest in New Delhi. He was on his way to the office of the Planning Commission in Rashtrapati Bhavan, when he collapsed a few yards away from there. He died on the way to hospital, at 10:15 a.m. (IST). It was reported, that he had been suffering from hypertension for ten months prior to his death. His remains were cremated at the Keoratola crematorium in Kolkata the following day.

Saha's study of the thermal ionisation of elements led him to formulate what is known as the Saha equation. This equation is one of the basic tools for interpretation of the spectra of stars in astrophysics. By studying the spectra of various stars, one can find their temperature and from that, using Saha's equation, determine the ionisation state of the various elements making up the star. This work was soon extended by Ralph H. Fowler and Edward Arthur Milne. Saha had previously reached the following conclusion on the subject.

It will be admitted from what has gone before that the temperature plays the leading role in determining the nature of the stellar spectrum. Too much importance must not be attached to the figures given, for the theory is only a first attempt for quantitatively estimating the physical processes taking place at high temperature. We have practically no laboratory data to guide us, but the stellar spectra may be regarded as unfolding to us, in an unbroken sequence, the physical processes succeeding each other as the temperature is continually varied from 3000 K to 40,000 K.

Saha also invented an instrument to measure the weight and pressure of solar rays and helped to build several scientific institutions, such as the Physics Department in Allahabad University and the Institute of Nuclear Physics in Calcutta. He founded the journal Science and Culture and was the editor until his death. He was the leading spirit in organizing several scientific societies, such as the National Academy of Science (1930), the Indian Physical Society (1934), Indian Institute of Science (1935). He was the Director at Indian Association for the Cultivation of Science during 1953–1956. The Saha Institute of Nuclear Physics, founded in 1943 in Kolkata, is named after him.

To actively participate in the planning of education, industrialization, health, and river valley development ,Saha stood as a candidate in the constituency of North-West Calcutta in the 1951 Loksabha election. He ran on the ticket of Union of Socialists and Progressives but Saha always maintained his independence. He was pitted against a powerful and well-funded candidate from Congress, Mr. Prabhu Dayal Himatsingka. Saha was not well funded for his campaign and wrote to his publisher in November 1951 to ask for a Rs 5,000 advance against the sale of his textbook, Treatise on Heat, "because I am standing for election in the house of the people from NW Calcutta". Saha won the contest by a margin of 16%.

Saha actively participated in the parliament in the areas of Education, Refugee and Rehabilitation, Atomic Energy, Multipurpose River Projects and Flood Control and long term planning. In the book "Meghnad Saha in Parliament" Saha is described as "Never unduly critical, Saha was so forthright, so incisive, so thorough in pointing out lapses that the treasury bench was constantly on the defensive. This is brought out by the way he was accused of leaving his laboratory and straying into a territory not his own. But the reason why he was slowly drifting towards this public role (he was never a politician in the correct sense of the term) was the gradually widening gulf between his dream and the reality—between his vision of an industrialised India and the Government implementation of the plan."

Saha was the chief architect of river planning in India and prepared the original plan for the Damodar Valley Project. His own observation with respect to his transition into government projects and political affairs is as follows:

Scientists are often accused of living in the "Ivory Tower" and not troubling their mind with realities and apart from my association with political movements in my juvenile years, I had lived in ivory tower up to 1930. But science and technology are as important for administration now-a-days as law and order. I have gradually glided into politics because I wanted to be of some use to the country in my own humble way.

Tributes to Saha[edit]
"Meghnad Saha's ionization equation (c. 1920), which opened the door to stellar astrophysics was one of the top ten achievements of 20th century Indian science [and] could be considered in the Nobel Prize class." — Jayant Narlika

"The impetus given to astrophysics by Saha's work can scarcely be overestimated, as nearly all later progress in this field has been influenced by it and much of the subsequent work has the character of refinements of Saha’s ideas." — Svein Rosseland

"He (Saha) was extremely simple, almost austere, in his habits and personal needs. Outwardly, he sometimes gave an impression of being remote, matter of fact, and even harsh, but once the outer shell was broken, one invariably found in him a person of extreme warmth, deep humanity, sympathy and understanding; and though almost altogether unmindful of his own personal comforts, he was extremely solicitous in the case of others. It was not in his nature to placate others. He was a man of undaunted spirit, resolute determination, untiring energy and dedication." — Daulat Singh Kothari

Mae Carol Jemison (born October 17, 1956) is an American engineer, physician, and former NASA astronaut. She became the first black woman to travel in space when she served as a mission specialist aboard the Space Shuttle Endeavour. Jemison joined NASA's astronaut corps in 1987 and was selected to serve for the STS-47 mission, during which she orbited the Earth for nearly eight days on September 12–20, 1992.

Born in Alabama and raised in Chicago, Jemison graduated from Stanford University with degrees in chemical engineering as well as African and African-American studies. She then earned her medical degree from Cornell University. Jemison was a doctor for the Peace Corps in Liberia and Sierra Leone from 1983 until 1985 and worked as a general practitioner. In pursuit of becoming an astronaut, she applied to NASA.

Jemison left NASA in 1993 and founded a technology research company. She later formed a non-profit educational foundation and through the foundation is the principal of the 100 Year Starship project funded by DARPA. Jemison also wrote several books for children and appeared on television several times, including in an episode of Star Trek: The Next Generation. She holds several honorary doctorates and has been inducted into the National Women's Hall of Fame and the International Space Hall of Fame.


Mae Carol Jemison was born in Decatur, Alabama, on October 17, 1956, the youngest of three children of Charlie Jemison and Dorothy Jemison (née Green). Her father was a maintenance supervisor for a charity organization, and her mother worked most of her career as an elementary school teacher of English and math at the Ludwig van Beethoven Elementary School in Chicago, Illinois. The family first lived in Woodlawn and later the Morgan Park neighborhoods. Jemison knew from a young age that she wanted to study science and someday go into space. The television show Star Trek, and in particular African-American actress Nichelle Nichols' portrayal of Lieutenant Uhura further stoked her interest in space.

Jemison enjoyed studying nature and human physiology, using her observations to learn more about science. Her mother encouraged her curiosity and both her parents were supportive of her interest in science, she did not always see the same support from her teachers. When Jemison told a kindergarten teacher she wanted to be a scientist when she grew up, the teacher assumed she meant she wanted to be a nurse. Seeing a lack of female astronauts during the Apollo missions also frustrated Jemison. She later recalled, "everybody was thrilled about space, but I remember being really really irritated that there were no women astronauts."

Jemison began studying ballet at the age of 8 or 9 and entered high school at 12 years old, where she joined the cheerleading team and the Modern Dance Club. he learned several styles of dance, including African and Japanese, as well as ballet, jazz, and modern dance. As a child, Jemison had aspirations of becoming a professional dancer. At the age of 14, she auditioned for the leading role of Maria in West Side Story. She did not get the leading role but was selected as a background dancer.

After graduating from Chicago's Morgan Park High School in 1973, Jemison entered Stanford University at the age of 16. Although she was young to be leaving home for college, Jemison later said it did not faze her because she was "naive and stubborn enough" There were very few other African-American students in Jemison's classes and she continued to experience discrimination from her teachers. In an interview with The Des Moines Register in 2008, Jemison said that it was difficult to go to Stanford at 16 but that her youthful arrogance may have helped her; she asserted that some arrogance is necessary for women and minorities to be successful in a white male dominated society.

At Stanford, Jemison served as head of the Black Students Union. She also choreographed a musical and dance production called Out of the Shadows. During her senior year in college, she struggled with the choice between going to medical school or pursuing a career as a professional dancer after graduation; she graduated from Stanford in 1977, receiving a B.S. degree in chemical engineering. and B.A. degree in African and African-American studies. While at Stanford, she also pursued studies related to her childhood interest in space and first considered applying to NASA.

Medical career

Jemison attended Cornell Medical School and during her training traveled to Cuba, to conduct a study funded by American Medical Student Association and to Thailand, where she worked at a Cambodian refugee camp. She also worked for Flying Doctors stationed in East Africa. During her years at Cornell, Jemison continued to study dance by enrolling in classes at the Alvin Ailey American Dance Theater. After graduating with a Doctorate in Medicine in 1981, she interned at Los Angeles County-USC Medical Center in 1982, and worked as a general practitioner for Ross–Loos Medical Group.

Jemison joined the staff of the Peace Corps in 1983 and served as a medical officer until 1985. She was responsible for the health of Peace Corps volunteers serving in Liberia and Sierra Leone. Jemison supervised the Peace Corps' pharmacy, laboratory, medical staff as well as providing medical care, writing self-care manuals, and developing and implementing guidelines for health and safety issues. She also worked with the Centers for Disease Control helping with research for various vaccines.

NASA career

Jemison at the Kennedy Space Center in 1992.

Upon returning to the United States after serving in the Peace Corps, Jemison settled in Los Angeles, California. In Los Angeles, she entered into private practice and took graduate level engineering courses. The flights of Sally Ride and Guion Bluford in 1983 inspired Jemison to apply to the astronaut program. Jemison first applied to NASA's astronaut training program in October 1985, but NASA postponed selection of new candidates after the Space Shuttle Challenger disaster in 1986. Jemison reapplied in 1987 and was chosen out of roughly 2,000 applicants to be one of the fifteen people in the NASA Astronaut Group 12, the first group selected following the destruction of Challenger. The Associated Press covered her as the "first black woman astronaut" in 1987. CBS featured Jemison as one of the country's "most eligible singles" on Best Catches, a television special hosted by Phylicia Rashad and Robb Weller in 1989.

Jemison's work with NASA before her shuttle launch included launch support activities at the Kennedy Space Center in Florida and verification of Shuttle computer software in the Shuttle Avionics Integration Laboratory (SAIL). On September 28, 1989, She was selected to join the STS-47 crew as Mission Specialist 4 and was also designated Science Mission Specialist, a new astronaut role being tested by NASA to focus on scientific experiments.


Jemison during Space Shuttle mission STS-47

Jemison flew her only space mission from September 12 to 20, 1992, on STS-47, a cooperative mission between the United States and Japan, as well as the 50th shuttle mission.Jemison logged 190 hours, 30 minutes, 23 seconds in space and orbited the earth 127 times. The crew was split into two shifts with Jemison assigned to the Blue Shift. Throughout the eight day mission, she began communications on her shift with the salute "Hailing frequencies open", a quote from Star Trek. Jemison took a poster from the Alvin Ailey American Dance Theater along with her on the flight. She also took a West African statuette and a photo of pioneering aviator Bessie Coleman, the first African American with an international pilot license.

STS-47 carried the Spacelab Japan module, a cooperative mission between the United States and Japan that included 43 Japanese and United States life science and materials processing experiments.Jemison and Japanese astronaut Mamoru Mohri were trained to use the Autogenic Feedback Training Exercise (AFTE), a technique developed by Patricia S. Cowings that uses biofeedback and autogenic training to help patients monitor and control their physiology as a possible treatment for motion sickness, anxiety and stress-related disorders.
Jemison aboard the Spacelab Japan module on Endeavour

Aboard the Spacelab Japan module, Jemison tested NASA's Fluid Therapy System, a set of procedures and equipment to produce water for injection, developed by Sterimatics Corporation. She then used IV bags and a mixing method, developed by Baxter Healthcare, to use the water from the previous step to produce saline solution in space. Jemison was also a co-investigator of two bone cell research experiments. Another experiment she participated in was to induce female frogs to ovulate, fertilize the eggs and then see how tadpoles developed in zero gravity.

Resignation from NASA

After her return to Earth, Jemison resigned from NASA in March 1993 with the intention of starting her own company. NASA training manager and author Homer Hickam, who had trained Jemison for her flight, later expressed some regret that she had departed.

Post-NASA career

Jemison served on the board of directors of the World Sickle Cell Foundation from 1990 to 1992. In 1993, she founded The Jemison Group Inc., a consulting firm which considers the sociocultural impact of technological advancements and design. Jemison also founded the Dorothy Jemison Foundation for Excellence and named the foundation in honor of her mother. One of the projects of the foundation is The Earth We Share, a science camp for students aged 12 to 16. Founded in 1994, camps have been held at Dartmouth College, Colorado School of Mines, Choate Rosemary Hall and other sites in the United States, as well as internationally in South Africa, Tunisia, and Switzerland.

Jemison was a professor of environmental studies at Dartmouth College from 1995 to 2002 where she directed the Jemison Institute for Advancing Technology in Developing Countries. In 1999, she also became an Andrew D. White Professor-at-Large at Cornell University. Jemison continues to advocate strongly in favor of science education and getting minority students interested in science. She is a member of various scientific organizations, such as the American Medical Association, the American Chemical Society, the Association of Space Explorers and the American Association for the Advancement of Science.

In 1999, Jemison founded BioSentient Corp and obtained the license to commercialize AFTE, the technique she and Mohri tested on themselves during STS-47.

In 2012, Jemison made the winning bid for the DARPA 100 Year Starship project through the Dorothy Jemison Foundation for Excellence. The Dorothy Jemison Foundation for Excellence was awarded a $500,000 grant for further work. The new organization maintained the organizational name 100 Year Starship. Jemison is the current principal of the 100 Year Starship.

In 2018, she collaborated with Bayer Crop Science and National 4-H Council for the initiative named Science Matters which was aimed at encouraging young children to understand and pursue agricultural sciences.


Jemison's first book, Find Where the Wind Goes (2001), is a memoir of her life written for children. She describes her childhood, her time at Stanford, in the Peace Corps and as an astronaut. School Library Journal found the stories about her earlier life to be the most appealing. Book Report found that the autobiography gave a realistic view into her interactions with her professors, whose treatment of was not based on her intelligence but on stereotypes of woman of color.

Her A True Book series of four children's books published in 2013 is co-authored with Dana Meachen Rau. Each book in the series has a "Find the Truth" challenge, true or false questions answers to which are revealed at the end of the story. School Library Journal found the series to be "properly tantalizing surveys" of the Solar System but criticized the inclusion of a few outdated theories in physics and astronomy.

Public profile

Mae Jemison at a symposium in 2009
LeVar Burton learned that Jemison was an avid Star Trek fan and asked her if she would be interested in being on the show. In 1993, Jemison appeared as Lieutenant Palmer in "Second Chances", an episode of the science fiction television series Star Trek: The Next Generation, becoming the first real-life astronaut to appear on Star Trek.

From 1999 to 2005, Jemison was appointed an Andrew Dickson White Professor-at-Large at Cornell University.

Jemison is an active public speaker who appears before private and public groups promoting science and technology. "Having been an astronaut gives me a platform," says Jemison,"but I'd blow it if I just talked about the Shuttle." Jemison uses her platform to speak out on the gap in the quality of health-care between the United States and the Third World. "Martin Luther King [Jr.] … didn't just have a dream, he got things done." Jemison has also appeared as host and technical consultant of the Discovery Channel science series World of Wonder.

In 2006, Jemison participated in African American Lives, a PBS television miniseries hosted by Henry Louis Gates, Jr., that traces the family history of eight famous African Americans using historical research and genetic techniques. Jemison found to her surprise that she is 13% East Asian in her genetic makeup. She also learned that some of her paternal ancestors were slaves at a plantation in Talladega County, Alabama.

Jemison participated in the Red Dress Heart Truth fashion show, wearing Lyn Devon, during the 2007 New York Fashion Week to help raise money to fight heart disease. In May of the same year, she was the graduation commencement speaker and only the 11th person in the 52-year history of Harvey Mudd College to be awarded an honorary D.Eng. degree.

On February 17, 2008, Jemison was the featured speaker for the 100th anniversary of the founding of the Alpha Kappa Alpha, the first sorority established by African-American college women. Jemison paid tribute to Alpha Kappa Alpha by carrying the sorority's banner with her on her shuttle flight. Her space suit is a part of the sorority's national traveling Centennial Exhibit. Jemison is an honorary member of Alpha Kappa Alpha.

Jemison participated with First Lady Michelle Obama in a forum for promising girls in the Washington, D.C. public schools in March 2009.

In 2014, Jemison also appeared at Wayne State University for their annual Dr. Martin Luther King, Jr. Tribute Luncheon. In 2016, she partnered with Bayer Corporation to promote and advance science literacy in schools, emphasizing hands-on experimentation.

She took part in the Michigan State University's lecture series, "Slavery to Freedom: An American Odyssey," in February 2017. In May 2017, Jemison gave the commencement speech at Rice University. She discussed the 100 Year Plan, science and education and other topics at Western Michigan University also in May 2017.

In 2017, LEGO released the "Women of NASA" set, with minifigures of Jemison, Margaret Hamilton, Sally Ride, and Nancy Grace Roman. The Google Doodle on March 8, 2019 (International Women's Day) featured a quote from Jemison: "Never be limited by other people’s limited imaginations."

Personal life

Jemison built a dance studio in her home and has choreographed and produced several shows of modern jazz and African dance.

In the spring of 1996, Jemison filed a complaint against a Texas police officer, accusing him of police brutality during a traffic stop that ended in her arrest. She was pulled over by Nassau Bay officer Henry Hughes for allegedly making an illegal U-turn and arrested after Hughes learned of an outstanding warrant on Jemison for a speeding ticket. In the process of arresting her, the officer twisted her wrist and forced her to the ground, as well as having her walk barefooted from the patrol car into the police station. In her complaint, Jemison said the officer physically and emotionally mistreated her.Jemison's attorney said she believed she'd already paid the speeding ticket years ago. She spent several hours in jail and was treated at an area hospital after release for deep bruises and a head injury. The Nassau Bay officer was suspended with pay pending an investigation, but the police investigation cleared him of wrongdoing. She filed a lawsuit against the city of Nassau Bay and the officer.

From Wikipedia, the free encyclopedia

Early life and career

Mahadeva Subramania Mani (Tamil: மகாதேவா சுப்ரமணிய கரங்கள்; 2 March 1908 in TanjoreTamil Nadu - 8 January 2003 in Bangalore) was an Indian entomologist especially famous for his studies on high altitude entomology.

Early school records and University of Madras, MA Degree certificate show his name as M. Subramanya. Later on, sometime early during his service career, he recorded his name as Mahadev Subra Mani a.k.a. Mahadeva Subra Mani a.k.a. M. S. Mani.

He had his early education at K. S. High School, Tanjore and passed his SSLC Examination in 1926. He then attended the Government College, Coimbatore and passed the Intermediate Examination, 1928. Later he went to medical studies just for one year 1929, at Madras Medical College and had to suspend further medical education due to financial constraints. He obtained in 1937, an M.A. degree, awarded by the University of Madras, on the basis of the Research Papers in Entomology, and finally, on the strength of his extensive scientific research, he was awarded by Agra University, D.Sc. in 1947, a degree of a Doctor of Science. The Chancellor was the late Ms. Sarojini Naidu, the then Governor of United Provinces, (Uttar Pradesh).

On 15 January 1933 he migrated to Calcutta to seek employment and build his career. He then joined Bangabasi College, Sealdah, Calcutta as a part-time demonstrator and tutor for Physics and earned a salary of Rs. 10/- per month. During this period he collaborated with Sir C. V. Raman on insect coloration. He worked at the Indian Museum and also as an honorary Research student at the Zoological Survey of India, Calcutta. He later on (1937) joined as a Research Assistant to Imperial Entomologist, Imperial Agricultural Research Institute, Pusa, Delhi, and a position from which he resigned in 1944. He worked with Dr. Hem Singh Pruthi at Pusa, and Dr. Birbal Sahni, then at Lucknow, who recognising the pioneering work in scientific research, strongly proposed M. S. Mani's Membership to the Royal Society, England. He was denied promotion while his ‘junior’ was promoted and hence he chose to seek his future elsewhere and resigned. He remained unemployed for sometime; he earned a living by working as an interpreter and German Language translator, during World War II, in the Censor Section of the Army H.Q., New Delhi, translating for the British Indian Army, 'official ' documents captured from the Germans. He would monitor radio broadcasts from Berlin and provide English transcripts. He also translated German language technical journals and scientific reports. As a matter of fact, he provided the English version of the German technology, for manufacturing hydrogenated oil ['Vanaspati'] in India to the founder of the manufacturing plant at Modinagar.

He left Delhi and joined as a lecturer in 1945, the teaching faculty of the Department of Zoology, St. John's College, Agra; during his long stint at St. John's College, he pioneered and established the School of Entomology in 1950, established a benchmark scientific excellence, where he became the Professor of Zoology and Entomology and appointed as the Head of the Department for Zoology, succeeding Prof. Lalit Prasad Mathur, who took over as the Registrar, Agra University. In recognition of his scientific output, both in quality and quantity, he was honoured by the University of Agra and awarded a D.Sc. degree, Doctor of Science. He pioneered fundamental research in entomology and received support from the highest levels and the University Grants Commission, eminent persons like Dr. Radhakrishnan, Zakir Hussein, etc., and established the School of Entomology in 1950, in the Campus of St. John's College, Agra.

From here he made many scientific expeditions to the Himalayas resulting in pioneering contributions to High Altitude Entomology. He later made studies in the Pamir and Caucasus ranges leading to his work on Biogeography in India. The University of Agra awarded him a DSc degree in 1947 for his thesis submitted in 12 volumes.

In 1956, he joined the ZSI as Deputy Director and retired as officiating director in 1968. In 1968 he returned to his first love, Scientific Research and became Emeritus Professor, at the School of Entomology, St. John's College, Agra and continued with his research work till 1984. He then finally left St. John's College and shifted to Madras, briefly worked with ZSI and since 1990 he was the Emeritus Professor, Botany Department at Presidency College, Madras and continued as a guide for PhD. research students, till 15 May 2002 when he moved to live temporarily, in Hyderabad, with his late sister Janaki's grandson, Jyotirmay Sharma, Editor, Times of India, Hyderabad. He then moved to Bangalore on 14 September 2002 to live with his only daughter, Mrs. Prema Subramanian and her husband V. S. Subramanian.

Scientific works

His published work includes over 250 original research papers, over 34 text books including his pioneering magnum opus, Ecology of Plant Galls.

His outstanding Research work has been on Taxonomy of parasitic Hymenoptera (Chalcidoidea and Proctotrupoidea), gall midges (Itonididae: Diptera) and ecology and histogenesis of plant galls. He is remembered most for his pioneering work in high altitude entomology. He led the first three Entomological Expeditions to the North West Himalaya in 1954, 1955 and 1956 and brought back a large collection of insects.

He published several books like High Altitude Entomology, Ecology and Biogeography of India etc. He led a team of Indian scientists to the Soviet Union for conducting jointly a research project in 1963 and represented India in the UNESCO programme on Man and Biosphere (MAB) at Oslo, Norway. He was fluent in written and spoken German, well read in Sanskrit, he also had a keen interest in Dutch, French and Russian languages.

Entomological Survey of the Himalaya, Alai-Pamir, Tien Shan, Kun Lun, Caucasus etc. His love of the mountains had begun as far back as 1950, when he went to the NilgirisMarudamalai Mountains with his son Visvanath; this was followed by similar visits to the mountains in north India, Dehra Dun 1950, Mussoorie/Chakrata 1952, NainitalGarhwal Himalaya, (Hartola, 1952), Punjab / Himachal Himalaya, (Dhaula Dhar Range, 1953) and to Kullu, Manali region leading to the three pioneering expeditions, in 1954, 1955 and 1956, beyond the Pir Panjal Range, to the inner or Great Himalayan Range, in Lahaul & Spiti regions. He also extensively trekked and went on insect collection work in the mountain regions, Alai-PamirTien ShanKun LunCaucasus, the Urals etc., of the former USSR, during his official tour in 1963, as the leader of the Indian team; he travelled extensively to various scientific institutes, at Moscow, Tbilisi, Leningrad, Kiev, Baku, Alma Ata, Samarkand, Tashkent etc.,. He also visited Oslo, in Norway on a similar invitation. He was a visiting professor at Tribhuvan University, Kathmandu, Nepal. He went on an insect collection trip, to the Pacific islands, Fiji and conducted a field trip off Vanua Levu, in the area of Taveuni island, across the International dateline. He trained Visvanath to work with his students, and who accompanied him on most field collection expeditions and taught him methods of preparing slides, mounting insect specimens and proof reading of Research papers. His first son, Visvanath was his constant companion on his mountain trails, starting with the first time at Mardamalai in 1950. Visvanath went on to trek in Sikkim, Bhutan in 1965 and climb on his own in the Kulti Nala glacier and Inner Himalayan Range of Spiti, in 1967.

Matthew Alexander Henson, (born August 8, 1866, Charles county, Maryland, U.S.—died March 9, 1955, New York, N.Y.), African American explorer who accompanied Robert E. Peary on most of his expeditions, including that to the North Pole in 1909.

Orphaned as a youth, Henson went to sea at the age of 12 as a cabin boy on the sailing ship Katie Hines. Later, while working in a store in Washington, D.C., he met Peary, who hired him in 1887 as a valet for his next expedition to Nicaragua (1888). Peary, impressed with Henson’s ability and resourcefulness, employed him as an attendant on his seven subsequent expeditions to the Arctic (1891–92; 1893–95; 1896; 1897; 1898–1902; 1905–06; 1908–09). In 1909 Peary and Henson, accompanied by four Inuit, became the first men to reach the North Pole, the rest of the crew having turned back earlier. Henson’s account of the journey, A Negro Explorer at the North Pole, appeared in 1912. The following year, by order of Pres. William Howard Taft, Henson was appointed a clerk in the U.S. Customs House in New York City, a post he held until his retirement in 1936. Henson received the Congressional medal awarded all members of the Peary expedition (1944).

S. Nambi Narayanan
Narayanan in 2017
Born 12 December 1941


Occupation Aerospace engineer

S. Nambi Narayanan (born 12 December 1945) is an Indian aerospace engineer who worked for the Indian Space Research Organisation. He was awarded the Padma Bhushan, the third-highest civilian award by the Government of India, in 2019. The scientist was instrumental in developing the Vikas engine that would be used for the first PSLV that India launched.As a senior official at the Indian Space Research Organisation (ISRO), he was in-charge of the cryogenics division.In 1994, he was falsely charged with espionage and arrested. The charges against him were dismissed by the Central Bureau of Investigation (CBI) in April 1996, and the Supreme Court of India declared him not guilty in 1998.

In 2018, the Supreme Court, through the bench of Dipak Misra, awarded Narayanan a compensation of ₹ 5,000,000 (roughly US$70,000), to be recovered from the Government of Kerala within eight weeks. However the Government of Kerala decided to give him ₹ 1.3 crore (₹ 13,000,000; roughly US$183,000). The apex court also constituted a committee headed by retired Supreme Court judge D. K. Jain to inquire into the role of officials of the Kerala police in the arrest of Narayanan.

Early life

S. Nambi Narayanan was born into a Tamil family  family on 12 December 1941 in Trivandrum  where he also completed his schooling at DVD Higher Secondary School. Dr.Nambi Naryanan wrote his autobiography in Malayalam  named "Ormakalude Bhramanapadham". Dr. Nambi's Malayalam  autobiography was inaugrated by Kerala Trivandrum Parliament Member Dr.Shashi Tharoor


Narayanan first met Vikram Sarabhai, the then Chairman of ISRO, in 1966 at the Thumba Equatorial Rocket Launching Station in Thumba, Thiruvananthapuram, while he worked as a payload integrator with another eminent scientist Y. S. Rajan there. Also chairman of the Space Science and technology Centre (SSTC) at the time, Sarabhai only recruited highly qualified professionals. In pursuit, Narayanan enrolled at the College of Engineering in Thiruvananthapuram for his MTech degree. Upon learning this, Sarabhai offered him leave for higher education if he made it to any of the Ivy League universities. Subsequently, Narayanan earned a NASA fellowship and was accepted into Princeton University in 1969. He completed his master's program there in chemical rocket propulsion under professor Luigi Crocco in a record ten months. Despite being offered a job in the US, Narayanan returned to India with expertise in liquid propulsion at a time when Indian rocketry was still solely dependent on solid propellants.

Narayanan introduced the liquid fuel rocket technology in India in the early 1970s, when A. P. J. Abdul Kalam's team was working on solid motors. He foresaw the need for liquid fuelled engines for ISRO's future civilian space programmes, and received encouragement from the then ISRO chairman Satish Dhawan, and his successor U. R. Rao. Narayanan developed liquid propellant motors, first building a successful 600 kilograms (1,300 lb) thrust engine in the mid-1970s and thereafter moving on to bigger engines.

In 1992, India signed an agreement with Russia for transfer of technology to develop cryogenic fuel-based engines and procurement of two such engines for ₹ 235 crore. However, it did not materialize after the US president George H. W. Bush wrote to Russia, raising objections against the transfer of technology and even threatening to blacklist the country from the select-five club. Russia, under Boris Yeltsin, succumbed to the pressure and denied the technology to India. To bypass this monopoly, India signed a new agreement with Russia to fabricate four cryogenic engines, alongside two mockups for a total of US$9 million, after floating a global tender without a formal transfer of technology. ISRO had already reached a consensus with Kerala Hitech Industries Limited which would have provided the cheapest tender for fabricating engines. But this failed to materialize due to the spy scandal of 1994.

After working for nearly two decades, with French assistance, Narayanan's team developed the Vikas engine used by several ISRO rockets including the Polar Satellite Launch Vehicle (PSLV) that took Chandrayaan-1 to the moon in 2008. The Vikas engine is used in the second stage of PSLV and as the second and the four strap-on stages of Geosynchronous Satellite Launch Vehicle (GSLV).

Espionage charges

In 1994, Narayanan was charged with leaking vital defence secrets to two alleged Maldivian intelligence officers, Mariam Rasheeda and Fauzia Hassan. Defense officials said the secrets pertained to highly confidential "flight test data" from experiments with rocket and satellite launches. Narayanan was among two scientists (the other being D. Sasikumaran) that were accused of selling the secrets for millions. However, his house seemed nothing out of the ordinary and did not show signs of the corrupt gains he was accused of.

Narayanan was arrested and spent 50 days in jail. He claims that officials from the Intelligence Bureau, who were the ones to interrogate him, wanted him to make false accusations against the top brass of ISRO. He alleges that two IB officials had asked him to implicate A. E. Muthunayagam, his boss and then Director of the Liquid Propulsion Systems Centre (LPSC). When he refused to comply, he was tortured until he collapsed and was hospitalised. He says his main complaint against ISRO is that it did not support him. Krishnaswamy Kasturirangan, who was ISRO chairman at the time stated that ISRO could not interfere in a legal matter.

In May 1996, the charges were dismissed as phony by the CBI. They were also dismissed by the Supreme Court in April 1998. In September 1999, the National Human Rights Commission (NHRC) passed strictures against the government of Kerala for having damaged Narayanan's distinguished career in space research along with the physical and mental torture to which he and his family were subjected. After the dismissal of charges against them, the two scientists, Sasikumar and Narayanan were transferred out of Thiruvananthapuram and were given desk jobs.

In 2001, the NHRC ordered the government of Kerala to pay him a compensation of ₹ 1 crore. He retired in 2001. The Kerala High Court ordered a compensation amount of Rs 10 lakhs to be paid to Nambi Narayanan based on an appeal from NHRC India in September 2012.

On 3 October 2012, The Hindu reported that the government of Kerala had dropped charges against the police officials who were alleged to have falsely implicated Narayanan in the espionage case on the grounds that over 15 years had passed since the case was initiated. The top officer involved in the case, Siby Mathews, was later appointed Chief Information Commissioner in Kerala (2011 - 2016). Kerala government settled the case filed against it by Narayanan by agreeing to a payment of ₹1.3 crore (US$170,000). As a result of this settlement Mr Narayanan agreed to withdraw his case in the Kerala High Court against the Kerala government.

On 14 Apr 2021 the Supreme Court of India ordered a CBI probe into the involvement of police officers in the conspiracy.

Demand for Justice
President Kovind presents Padma Bhushan to Shri S. Nambi Narayanan

On 7 November 2013, Narayanan pushed for justice in his case, seeking to expose those behind the conspiracy. He says that this case will 'discourage' the youth.

On 14 September 2018, the Supreme Court appointed a three-member panel headed by its former judge to probe the "harrowing" arrest and alleged torture of former space scientist Nambi Narayanan in the 'ISRO spy scandal' that turned out to be fake.

A three-judge Bench led by Chief Justice Dipak Misra also awarded Mr. Narayanan Rs. 50 lakh in compensation for the "mental cruelty" he suffered all these years. The reprieve comes almost a quarter of century after Mr. Narayanan began his legal battles in various forums for his honour and justice. In addition to this, the government of Kerala has decided to give him Rs 1.3 crore as compensation

On 26 January 2019, he was conferred with the Padma Bhushan award by the Government of India.

The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Medical Sciences in 1992. He received the Chevalier of the National Order of Merit from François Mitterrand in 2003.

All India Institute of Medical Sciences, Delhi

Born on 4 November 1949 in Amritsar, in the Indian state of Punjab, Mehra did his schooling at Bishop Cotton School, Simla and earned his graduate degree (BSc) with human anatomy, physiology and biochemistry as optional subjects from Government Medical College, Amritsar in 1969 before moving to Delhi to complete his master's degree (MSc) in human anatomy at the All India Institute of Medical Sciences, Delhi (AIIMS). He continued at AIIMS for his doctoral studies and after securing a PhD in 1975 on the immunology of leprosy, did post-doctoral work on histocompatibility and immunogenetics at the laboratory of Jon van Rood in the Netherlands and later with John A. Hansen at Fred Hutchinson Cancer Research Center, Seattle. On his return to India, he joined his alma mater, AIIMS, as a pool officer in 1977 In 1979, he was elevated to lecturer with the additional responsibility of the clinical and research activities of the Histocompatibility Laboratory established under the Department of Anatomy in 1977, the year he joined AIIMS In 1993, the laboratory, which served as the core laboratory in India for workshops on histocompatibility as well as a base for researches on human leukocyte antigen (HLA), was upgraded to a full-fledged department under the name "Department of Transplant Immunology and Immunogenetics", which he headed as its founding chair, in the capacity of a professor and served out his career at AIIMS in that position. He also served as the member secretary of the Research Advisory Council and chaired the Dean's Research Committee (DRC) at AIIMS At the time of his official retirement from service in 2004, he was serving as the Dean of Research and post-retirement, he holds the Dr. C. G. Pandit National Chair of the Indian Council of Medical Research (ICMR) at AIIMS, continuing his research at the institution

Mehra resides in AIIMS Campus, in Ansari Nagar, New Delhi.

A hand affected by rheumatoid arthritis

Mehra, whose research has covered various aspects of histocompatibility and immunogenetics, started his work on the subjects during his post-doctoral days in Europe, and at John Hansen's laboratory in Seattle, where he used DNA-based technologies of HLA analysis to study the immunogenetic aspects of rheumatoid arthritis Later, in India, he studied HLA-linked genes and identified that a subtype of HLA-DR2 carried a unique class II haplotype which made humans susceptible to diseases such as leprosy and tuberculosis. He also differentiated the Indian rheumatoid arthritis and insulin-dependent diabetes mellitus patients from the Western Caucasian patients by demonstrating that the former showed a pattern of HLA-DR and HLA-DQ association and these studies helped in characterizing the Indian population with regard to its genomic diversity. His group demonstrated that HLA genes with specific pockets in the peptide binding region controlled the severity of mycobacterial diseases, which was a first-time discovery. Together with Ajay Kumar Baranwal of AIIMS Delhi and Brian D. Tait of the Australian Red Cross Blood Service, he carried out a research project, Antibody Repertoire and graft outcome following solid organ transplantation, which assisted in the prediction of graft rejection and had significance in organ and bone marrow transplantation He also guided a team of scientists in a project based on polymorphic immunomodulatory genes for developing molecular medicine to combat infectious, autoimmune and rheumatological diseases. His research has been published by way of over 450 articles; of which 287 are listed by ResearchGate. Besides, he has published a book, The HLA Complex in Biology and Medicine: A Resource Book, and has contributed chapters to books published by other researchers, including Textbook of Biochemistry, Biotechnology, Allied and Molecular Medicine. His researches have been cited by many authors, too.

The All India Institute of Medical Sciences, Delhi established a Histocompatibility Laboratory under its Department of Anatomy in 1977, the year Mehra joined as a pool officer at the institution. Subsequently, he took over the activities of the laboratory and by the time he was promoted to professor in 1993, the laboratory had developed into a referral centre as well as a core laboratory for histocompatibility workshops and AIIMS elevated its status to an independent department, the Department of Transplant Immunology and Immunogenetics, with Mehra as its founding chair. Under the aegis of the new department and in association with Dadhichi Deh Dan Samiti, he established the first Asian Indian Donor Marrow Registry (AIDMR), a database of the donors of bone marrow in India in 1994. He would later explain the details of the registry through an article, Asian Indian donor marrow registry: All India Institute of Medical Sciences experience, published in Transplantation Proceedings in 2007. He has delivered a number of keynote addresses or invited lectures including MedIndia 2003 2013 seminar of human genomics at the Guru Nanak Dev University, 2016 India-Japan Regulatory Symposium, and a Guest lecture series organized by Manipur University in 2016. He has also mentored around 60 masters and doctoral research scholars in their studies.

Professional associations

Mehra is the founding president of the Federation of Immunological Societies of Asia Oceania (FIMSA) and has served as its vice president thereafter. He was also the organizer of the Advanced Course on Basic and Translational Immunology, conducted by FIMSA in collaboration with the International Union of Immunological Societies (IUIS) and Indian Immunology Society (IIS) in March 2012; he has also served as a member of the council of IUIS. He presides over the Indian Society of Histocompatibility and Immunogenetics and was a member of the faculty of the 2016 edition of ISHICON held in December 2016 at Postgraduate Institute of Medical Education and ResearchChandigarh. He sits on the National Board of Advisors of the Center for Stem Cell Science, and the Advisory Board of Indus Foundation and is a trustee of the Board of Immunology Foundation as well as a member of the Publication Advisory Board of the Indian National Science Academy.

Namdeo Nimgade (1920-2011) was an agricultural scientist at the Indian Agricultural Research Institute. He was born into an ‘untouchable’ family of landless bonded labourers in Sathgaon, in western India. He is the author of In the Tiger’s Shadow, an inspiring autobiography.

In The Tiger’s Shadow

‘This book must be read not only by all those who want to understand the dalit universe but also by those who enjoy a good Indian book in English’DNA, Mumbai

Born into a family of landless bonded labourers in the dustbowl of Sathgaon in western India, Namdeo Nimgade is 14 when he finally manages to attend his village school where, being an ‘untouchable’, he has to stand on the ‘hot verandah and listen to lessons through a window’. Inspired by Dr B.R. Ambedkar, he steadfastly pursues his education. Graduating from Nagpur, Nimgade goes on to complete his PhD in soil science from the University of Wisconsin in 1962—perhaps the first dalit after Ambedkar to earn a doctorate from an American university. In the 1950s, as an associate at the Indian Agricultural Research Institute in Delhi, Nimgade gets to spend time with Dr Ambedkar. Throughout his life, Nimgade remains singularly committed to the ambedkarite movement. Nimgade narrates incidents in his life with candour and delightful humour—whether recounting his great-grandfather Ganba’s combat with a tiger in a forest, or his ‘forbidden’ love for a non-dalit woman. Moving away from the framework of victimhood narratives, Nimgade’s life is an inspiring story of triumph against odds.

‘Our family name Nimgade probably derives from the neem tree, which is known for its healing properties and health benefits. Many people from our untouchable community bear names referring to trees or plants, such as my brother-in-law, Khobragade—which refers to a coconut. There’s similarly Ambagade, referring to mango, Jamgade to guava and Borkar to berry. Quite likely, these arboreal names derive from the peaceful Buddhist period in Indian history, and are cited as further evidence that many of India’s untouchables were previously Buddhist.’

Pramod Karan Sethi
Born 28 November 1927

Varanasi, India
Died 6 January 2008 (aged 80)

Nationality Indian
Other names P. K. Sethi
Occupation orthopaedic surgeon, inventor
Known for Jaipur foot

Pramod Karan Sethi (28 November 1927 – 6 January 2008) was an Indian orthopaedic surgeon. With Ram Chandra Sharma, he co-invented the "Jaipur foot", an inexpensive and flexible artificial limb, in 1969.

He was awarded the Magsaysay Award for Community Leadership in 1981 and the Padma Shri by the Government of India in 1981.

Personal life and career

Sethi was born at Varanasi (then Banaras), where his father Nihal Karan Sethi, himself a renowned scientist, was a physics professor at Banaras Hindu University. Sethi trained as a general surgeon at Agra under G. N. Vyas. In 1958, he specialised in orthopaedics, when the Sawai Man Singh Hospital in Jaipur where he worked needed an orthopaedics department because of a Medical Council of India inspection. He later cited his lack of qualifications in orthopaedics as an advantage in developing the Jaipur foot. Much of his practice was in physiotherapy, including the rehabilitation of amputees. He retired in 1981. He was the founder of MVSS.

He was married to Sulochana, and the couple had a son and three daughters. Sethi died of cardiac arrest in JaipurIndia.

Jaipur foot

The Jaipur foot is made of rubber and wood and is probably the lowest cost prosthetic limb available in the world. The International Red Cross Committee has used it extensively in Afghanistan and other places to help amputees. Several injured soldiers in the Kargil war were benefited due to the Jaipur foot. Sethi was recognized by the Guinness Book of World Records for helping a large number of amputees in obtaining mobility again. The Indian dancer and actor Sudha Chandran was one of his patients.

Ram Chandra Sharma, an illiterate craftsman, is the co-inventor of the foot. The original idea of the Jaipur foot is supposed to have come to him serendipitously while he was riding a bicycle and had a flat tire.


Sethi was awarded the Magsaysay Award for Community Leadership in 1981, the Padma Shri by the Government of India in 1981  and he also won a major Rotary International award. He was elected a fellow of the British Royal College of Surgeons.
