Harish-Chandra, whose full name was Harish-Chandra Mehrotra, was an eminent Indian mathematician and physicist. He was born on October 11, 1923, in Kanpur, India, and passed away on October 16, 1983, in Princeton, New Jersey, United States. Harish-Chandra made significant contributions to the fields of mathematics and theoretical physics, particularly in the areas of representation theory, harmonic analysis, and the mathematical foundations of quantum mechanics. His work focused on the study of Lie groups and their representations, which are important mathematical structures used to analyze symmetry in various physical and mathematical contexts.
