Владимир Александрович Фок
Russian theoretical physicist. Born 1898, died 1974.
V.A. Fock was educated at the University of Leningrad, where he worked from 1924. He became a professor there in 1932, and from 1939 a member of the Soviet Union's Academy of Sciences.
In 1930, he presented a development of D. Hartree's quantum mechanical work, resulting in what is now known as the Hartree-Fock Method (a.k.a. the self-consistent field method).
Fock also made major contributions to the work with the General Theory of Relativity.
