Harish-Chandra (Harish Chandra Mehrotra) was born in Kanpur (then Cawnpore), British India. His was educated at BNSD Intermediate College, Kanpur, and at the University of Allahabad. After receiving his Masters Degree in 1943, he moved to Bangalore for further studies. In 1945, he moved to University of Cambridge as a research student of Paul Dirac. 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 life long friends. During this time he became increasingly interested in mathematics. He obtained his PhD in 1947 and during the same year he moved to the USA.

When Dirac visited Princeton, Harish-Chandra worked as his assistant.

He was influenced by the mathematicians Hermann Weyl and Claude Chevalley. From 1950 to 1963 was at the Columbia University and carried out some of his best research, especially on representations of semisimple Lie groups. During this period he established as his special area the study of the discrete series representations of semisimple Lie groups — which are the closest analogue of the Peter-Weyl theory in the non-compact case. The methods were formidable and inductive, using Lie group decompositions.

He is also known for work with Armand Borel founding the theory of arithmetic groups; and for papers on finite group analogues. He enunciated a philosophy of cusp forms, a precursor of the Langlands philosophy''.

He was a faculty member at the Institute for Advanced Study in New Jersey from 1963. He was appointed IBM von Neumann Professor in 1968.

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. Dr. T. N. Trivedi, head of the mathematics department of V.S.S.D College has been very instrumental in organizing the events.
