Subrahmanyan Chandrasekhar nsIn existographies, Subrahmanyan Chandrasekhar (1910-1995) (IQ:170|#227) (GAE:#) (CR:12) was an Indian-born American astrophysicist noted for his 1939 book An Introduction to the Study of Stellar Structure, in which he devotes the first chapter, on astrophysical thermodynamics, to laying out a thermodynamic foundation for the study of stellar structure using the thermodynamics of Greek mathematician Constantin Caratheodory (1908), in particular the so-called Caratheodory theorem. [1]

Black holes
In 1939, Chandrasekhar, in his An Introduction to the Study of Stellar Structure, suggested the idea of black holes. A similar concept, to note, of “black body stars” was suggested in William Sidis' 1925 The Animate and the Inanimate. [3]

Education
Chandrasekhar completed his BS in physics in 1930 at Presidency College, after which he completed his PhD in 1933 at Cambridge under English statistical thermodynamicist Ralph Fowler, where he took the relativistic quantum mechanics course of Paul Dirac four times.

He then entered a fellowship at Trinity College where he established friendship with English astronomer Arthur Eddington. In 1936, he worked at Harvard for a term and the following year joined the faculty at the University of Chicago, obtaining emeritus status there in 1985. [2]

Recognition
In 1983 he and American astrophysicist William Fowler shared the Nobel Prize in physics for his study of the physical processes underlying the structure and evolution of stars.
