Komaravolu Chandrasekharan (21 November 1920 – 13 April 2017) was a professor at ETH Zurich and a founding faculty member of School of Mathematics, Tata Institute of Fundamental Research (TIFR). He is known for his work in number theory and summability. He received the Padma Shri, the Shanti Swarup Bhatnagar Award, and the Ramanujan Medal, and he was an honorary fellow of TIFR. He was president of the International Mathematical Union (IMU) from 1971 to 1974.
Chandrasekharan was born on 21 November 1920 in Machilipatnam, Andhra Pradesh. Chandrasekharan completed his high school from Bapatla village in Guntur from Andhra Pradesh. He completed M.A. in mathematics from the Presidency College, Chennai and a PhD from the Department of Mathematics, University of Madras in 1942, under the supervision of K. Ananda Rau.
When Chandrasekharan was with the Institute for Advanced Study, Princeton, US, Homi Bhabha invited Chandrashekharan to join the School of Mathematics of the Tata Institute of Fundamental Research (TIFR). Chandrashekharan persuaded mathematicians L. Schwarz, C. L. Siegel and others from all over the world to visit TIFR and deliver lectures. In 1965, Chandrasekharan left the Tata Institute of Fundamental Research to join the ETH Zurich, where he retired in 1988.
He was a fellow of the American Mathematical Society.
