Subrahmanyan Chandrasekhar

On this date in 1910, Subrahmanyan Chandrasekhar was born in Lahore, now in Pakistan but at the time a part of British India. He earned a B.S. with honors in physics from Presidency College in India in 1930 and a Ph.D. in physics from Cambridge University in England in 1933. After his graduation, Chandrasekhar was awarded a Prize Fellowship at Trinity College from 1933 to 1937. He worked as a research associate and professor at the University of Chicago from 1937 to 1995, and became an American citizen in 1953. He married Lalitha Doraiswamy in 1936.

Chandrasekhar was an astrophysicist who made influential discoveries about white dwarf stars in 1930 when he was only 20. He is known for discovering the Chandrasekhar limit. He found that stars with masses below the Chandrasekhar limit form white dwarfs after they collapse, but stars with masses above the limit continue collapsing. His studies of stellar evolution were influential in the discovery of black holes.

He won the 1983 Nobel Prize in Physics with William Fowler for their work with stellar structure and evolution. He published 10 books, including Introduction to the Study of Stellar Structure (1939), Principles of Stellar Dynamics (1942) and The Mathematical Theory of Black Holes (1983).

Chandrasekhar was the nephew of C. V. Raman, who was awarded the Nobel Prize for Physics in 1930. He became a naturalized U.S. citizen in 1953. He died of a heart attack at the University of Chicago Hospital in 1995, 20 years after his first heart attack. His wife died at age 102 in 2013.
