<br />
==Early life==<br />
Harish-Chandra was born in [[Kanpur]].<ref>http://www.hri.res.in/about/harish-chandra/</ref> He was educated at [[BNSD Inter College|B.N.S.D. College, Kanpur]] and at the [[University of Allahabad]].<ref name="www-history.mcs.st-andrews.ac.uk">http://www-history.mcs.st-andrews.ac.uk/Biographies/Harish-Chandra.html</ref> After receiving his master's degree in Physics in 1943, he moved to the [[Indian Institute of Science]], Bangalore for further studies in theoretical physics and worked with [[Homi J. Bhabha]].<br />
<br />
In 1945, he moved to [[University of Cambridge]], and worked as a research student under [[Paul Dirac]].<ref name="www-history.mcs.st-andrews.ac.uk"/> While at Cambridge, he attended lectures by [[Wolfgang Pauli]], and during one of them pointed out a mistake in Pauli's work. The two were to become lifelong friends. During this time he became increasingly interested in mathematics. At Cambridge he obtained his PhD in 1947.<br />
<br />
==Honors and awards==<br />
<br />
He was a member of the [[United States National Academy of Sciences|National Academy of Sciences]] and a [[Fellow of the Royal Society]].<ref name="frs"/> He was the recipient of the [[Cole Prize]] of the [[American Mathematical Society]], in 1954. The [[Indian National Science Academy]] honoured him with the [[Srinivasa Ramanujan Medal]] in 1974. In 1981, he received an honorary degree from [[Yale University]].<br />
<br />
The mathematics department of V.S.S.D. College, Kanpur celebrates his birthday every year in different forms, which includes lectures from students and professors from various colleges, institutes and students' visit to Harish-Chandra Research Institute.<br />
<br />
The Indian Government named the [[Harish-Chandra Research Institute]], an institute dedicated to Theoretical Physics and Mathematics, after him.<br />
<br />
[[Robert Langlands]] wrote in a biographical article of Harish-Chandra:<br />
<br />
{{quote|He was considered for the [[Fields Medal]] in 1958, but a forceful member of the selection committee in whose eyes [[René Thom|Thom]] was a [[Nicolas Bourbaki|Bourbakist]] was determined not to have two. So Harish-Chandra, whom he also placed on the Bourbaki camp, was set aside.}}<br />
<br />
He was also a recipient of the [[Padma Bhushan]] in 1977.<ref name="Padma Awards">{{cite web | url=http://mha.nic.in/sites/upload_files/mha/files/LST-PDAWD-2013.pdf | title=Padma Awards | publisher=Ministry of Home Affairs, Government of India | date=2015 | access-date=21 July 2015}}</ref><br />
