D. D. Kosambi
Born July 31, 1907
Kosben, Goa
Died June 29, 1966
Pune, Maharashtra
Occupation Mathematician and Marxist historian

Damodar Dharmananda Kosambi (July 31, 1907–June 29, 1966) was an Indian mathematician, statistician, historian, and polymath who contributed to genetics by introducing Kosambi's map function. He is well-known for his work in numismatics and for compiling critical editions of ancient Sanskrit texts. His father, Dharmananda Damodar Kosambi, had studied ancient Indian texts with a particular emphasis on Buddhism and its literature in the Pali language. Damodar Kosambi emulated him by developing a keen interest in his country's yesteryears. Kosambi was also a Marxist[1] historian specializing in ancient India who employed the historical materialist approach in his work. He is described as "the patriarch of the Marxist school of Indian historiography".[1] Kosambi was critical of the policies of then Prime Minister Jawaharlal Nehru, which, according to him, promoted capitalism in the guise of democratic socialism. He was an enthusiast of the Chinese revolution and its ideals, and, in addition, a leading activist in the World Peace Movement. In the opinion of the historian Irfan Habib, "D. D. Kosambi and R.S. Sharma, together with Daniel Thorner, brought peasants into the study of Indian history for the first time."[2]

Early life

After a few years of schooling in India, in 1918 D.D. Kosambi and his elder sister, Manik Kosambi, traveled to Cambridge, Massachusetts with his father, who was assisting Harvard University professors in compiling a critical edition of the Visuddimagga, a book on Buddhist philosophy. There he spent a year in the Grammar school and then was admitted to the Cambridge High and Latin School in 1920. He became a member of the Cambridge branch of American Boy Scouts.

It was here in Cambridge that he befriended another prodigy of the time, Norbert Wiener, whose father Leo Wiener was the elder Kosambi's colleague at Harvard University.

Kosambi excelled in his final school examination and was one of the few candidates who was exempt on the basis of merit from necessarily passing an entrance examination essential at the time to gain admission to Harvard University. He enrolled in Harvard in 1924, but eventually postponed his studies, and returned to India. He stayed with his father who was now working in the Gujarat University, and was in the close circles of Mahatma Gandhi.

In January 1926, Kosambi returned to the US with his father, who once again studied at Harvard University for a year and half. Kosambi studied mathematics under George David Birkhoff, who wanted him to concentrate on mathematics, but the ambitious Kosambi instead took many diverse courses excelling in each of them. In 1929, Harvard awarded him the Bachelor of Arts degree with a summa cum laude. He was also granted membership to the esteemed Phi Beta Kappa Society, the oldest undergraduate honours organization in the United States. He returned to India soon after.He was technical consultant to the Chinese government.

Banaras and Aligarh

He obtained the post of professor at the Banaras Hindu University (BHU), teaching German alongside mathematics. He struggled to pursue his research on his own, and published his first research paper, "Precessions of an Elliptic Orbit" in the Indian Journal of Physics in 1930.

In 1931, Kosambi married Nalini, daughter of a very wealthy and distinguished member of the Madgaonkar family. It was in this year that he was hired by mathematician Andre Weil, then Professor of Mathematics at Aligarh Muslim University, to the post of lecturership in mathematics at Aligarh.[3] His other colleagues at Aligarh included Vijayraghavan. During his two years stay in Aligarh, he produced eight research papers in the general area of Differential Geometry and Path Spaces. His fluency in several European languages allowed him to publish some of his early papers in French, Italian and German journals in their respective languages.

Fergusson College, Pune

In 1933, he joined the Deccan Education Society’s Fergusson College in Pune, where he taught mathematics for the next 12 years. In 1935, his eldest daughter, Maya was born, while in 1939, the youngest, Meera, a well-known sociologist and feminist was born.

In Pune, while teaching mathematics and conducting research in the field, he started his interdisciplinary pursuit. In 1944 he published a small article of 4 pages titled ‘The Estimation of Map Distance from Recombination Values’ in Annals of Eugenics, in which he introduced what later came to be known as Kosambi's map function.

One of the most important contributions of Kosambi to statistics is the widely known technique called proper orthogonal decomposition (POD). Although it was originally developed by Kosambi in 1943, it is now referred to as the Karhunen–Loève expansion. In the 1943 paper entitled 'Statistics in Function Space' presented in the Journal of the Indian Mathematical Society, Kosambi presented the Proper Orthogonal Decomposition some years before Karhunen (1945) and Loeve (1948). This tool has found application to such diverse field as image processing, signal processing, data compression, oceanography, chemical engineering and fluid mechanics. Unfortunately this most important contribution of his is barely acknowledged in most papers that utilize the POD method. In recent years though, it is heartening to note that some authors have indeed referred to it as the Kosambi-Karhunen-Loeve decomposition.[citation needed]

It was his studies in numismatics that initiated him in the field of historical research. He made a thorough study of Sanskrit and ancient literature, and he started his classic work on the ancient poet Bhartrihari. He published his critical editions of Bhartrihari's Shatakatrayee and Subhashitas during 1945-1948. It was during this period that he started his political activism, coming close to the radical streams in the ongoing Independence movement, especially the Communist Party of India. He became an outspoken Marxist and wrote some political articles.

Tata Institute of Fundamental Research

In 1945, Homi J. Bhabha invited Kosambi to join the Tata Institute of Fundamental Research (TIFR) as Professor of Mathematics, which he accepted. After independence, in 1948-49 he was sent to England and the US as a UNESCO Fellow to study the theoretical and technical aspects of the computer. During this time, he was a visiting professor of geometry at the University of Chicago. He spent some time at the Institute for Advanced Study in Princeton, New Jersey. In London, he started his long-lasting friendship with indologist and historian A.L. Basham.

After his return to India, in the Cold War circumstances, he was increasingly drawn into the World Peace Movement and served in his capacity as Member of the World Peace Council. He became a tireless crusader of peace, campaigning against the nuclearisation of the world. Kosambi's solution to India's energy needs was in sharp conflict with the ambitions of the Indian ruling class. He stressed on alternative energy sources, like solar power. His activism in the peace movement took him to Beijing, Helsinki and Moscow. However, during this period he relentlessly pursued his diverse research interests, too. Most importantly, he worked on his Marxist rewriting of ancient Indian history, which culminated in his book, An Introduction to the Study of Indian History (1956).

He visited China many times during 1952-62 and was able to watch the Chinese revolution very closely, making him critical of the way modernisation and development were envisaged and pursued by the Indian ruling classes. All these contributed in straining his relationship with the Indian government and Bhabha, eventually leading to Kosambi's exit from the Tata Institute of Fundamental Research in 1962.

Post-TIFR days

His exit from the TIFR gave Kosambi the opportunity to concentrate on his research in ancient Indian history culminating into his book, The Culture and Civilisation of Ancient India, which was published in 1965 by Routledge. The book was translated in German, French and Japanese and was widely acclaimed. He also utilised his time in archaeological studies, and contributed in the field of statistics and number theory. His article on numismatics was published in February 1965 in Scientific American.

Due to the efforts of his friends and colleagues, in June 1964, Kosambi was appointed as a Scientist Emeritus of the Council of Scientific and Industrial Research (CSIR) affiliated to the Maharashtra Vidnyanvardhini in Pune. He got involved in many historical, scientific and archaeological projects (even writing stories for children). But most of his works that he produced in this period could not be published during his lifetime. On June 29, 1966, he died in Pune. He was posthumously decorated with the Hari Om Ashram Award by the government of India's University Grant Commission in 1980.

His friend A.L. Basham, a well-known indologist, wrote in his tribute to Kosambi:

At first it seemed that he had only three interests, which filled his life to the exclusion of all others- ancient India, in all its aspects, mathematics and the preservation of peace. For the last, as well as for his two intellectual interests, he worked hard and with devotion, according to his deep convictions. Yet as one grew to know him better one realized that the range of his heart and mind was very wide...In the later years of his life, when his attention turned increasingly to anthropology as a means of reconstructing the past, it became more than ever clear that he had a very deep feeling for the lives of the simple people of Maharashtra.[4]

Kosambi's historiography

As a historian, Kosambi is revolutionised Indian history writing with his Marxist approach, crucially diverting from the mainstream nationalist and imperialist schools. He understood history in terms of the dynamics of socio-economic formations rather than just a chronological narration of "episodes" or the feats of a few great men - kings, warriors or saints. In the very first paragraph of his classic work, An Introduction to the Study of Indian History, he gives an insight into his methodology as a prelude to his life work on ancient Indian history:

"THE light-hearted sneer “India has had some episodes, but no history“ is used to justify lack of study, grasp, intelligence on the part of foreign writers about India’s past. The considerations that follow will prove that it is precisely the episodes — lists of dynasties and kings, tales of war and battle spiced with anecdote, which fill school texts — that are missing from Indian records. Here, for the first time, we have to reconstruct a history without episodes, which means that it cannot be the same type of history as in the European tradition."[5]

According to A. L. Basham, "An Introduction to the Study of Indian History is in many respects an epoch making work, containing brilliantly original ideas on almost every page; if it contains errors and misrepresentations, if now and then its author attempts to force his data into a rather doctrinaire pattern, this does not appreciably lessen the significance of this very exciting book, which has stimulated the thought of thousands of students throughout the world."[6]

Professor Sumit Sarkar says:"Indian Historiography, starting with D.D. Kosambi in the 1950s, is acknowledged the world over - wherever South Asian history is taught or studied - as quite on a par with or even superior to all that is produced abroad. And that is why Irfan Habib or Romila Thapar or R.S. Sharma are figures respected even in the most diehard anti-Communist American universities. They cannot be ignored if you are studying South Asian history."[7]
