was a professor at [[ETH Zurich]]<ref>[https://www.bi.id.ethz.ch/personensuche/detail.do?pid=17064&lang=EN Komaravolu Chandrashekhar ]</ref> 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 [[Srinivasa Ramanujan Medal|Ramanujan Medal]], and he was an honorary fellow of TIFR. He was president of [[International Mathematical Union|the International Mathematical Union (IMU)]] from 1971 to 1974.

==Biography==
Chandrasekhar was born on 21 November 1920 in Machilipatnam in modern-day [[Andhra Pradesh]]. Chandrasekhar completed his high school from Bapatla village in [[Guntur]] from [[Andhra Pradesh]]. He completed his 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]].<ref name=TIFR/>

When Chandrasekhar was with the [[Institute for Advanced Study]], Princeton, US, [[Homi J. Bhabha|Homi Bhabha]] invited Chandrashekhar to join the School of Mathematics of the [[Tata Institute of Fundamental Research]] (TIFR). Chandrashekhar persuaded mathematicians, such as [[L. Schwarz]] and [[C. L. Siegel]], from all over the world to visit TIFR and deliver courses of lectures. In 1965, Chandrasekhar left the Tata Institute of Fundamental Research to join the [[ETH Zurich]],<ref name=TIFR /> where he retired in 1988.<ref>
