1923

Harish-Chandra Mehrotra FRS (11 October 1923 – 16 October 1983) was an Indian-American mathematician and physicist who did fundamental work in representation theory, especially harmonic analysis on semisimple Lie groups.

Harish-Chandra Mehrotra was born in Kanpur.

He was educated at B.N.S.D. College, Kanpur and at the University of Allahabad.

1940

After receiving his master's degree in physics in 1940, he moved to the Indian Institute of Science, Bangalore for further studies under Homi J. Bhabha.

1945

In 1945, he moved to University of Cambridge, and worked as a research student under Paul Dirac.

While at Cambridge, he attended lectures by Wolfgang Pauli, and during one of them, Mehrotra pointed out a mistake in Pauli's work.

The two became lifelong friends.

During this time he became increasingly interested in mathematics.

1947

He obtained his PhD, Infinite Irreducible Representations of the Lorentz Group, at Cambridge in 1947 under Dirac.

He was a member of the National Academy of Sciences and a Fellow of the Royal Society.

1954

He was the recipient of the Cole Prize of the American Mathematical Society, in 1954.

1958

"He was considered for the Fields Medal in 1958, but a forceful member of the selection committee in whose eyes Thom was a Bourbakist was determined not to have two. So Harish-Chandra, whom he also placed on the Bourbaki camp, was set aside."

1969

Starting in 1969, Mehrotra began to experience heart attacks.

1970

A second and third heart attack occurred in 1970 and 1982, respectively.

From then, his physical capabilities began to decline.

1974

The Indian National Science Academy honoured him with the Srinivasa Ramanujan Medal in 1974.

1977

He was also a recipient of the Padma Bhushan in 1977.

1981

In 1981, he received an honorary degree from Yale University.

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.

The Indian Government named the Harish-Chandra Research Institute, an institute dedicated to Theoretical Physics and Mathematics, after him.

Robert Langlands wrote in a biographical article of Harish-Chandra:

1983

A fourth heart attack occurred in 1983, leaving him mostly bedridden and in isolation.

On the day after a conference organized for him and mathematician Armand Borel took place, Mehrotra died from his final heart attack.
