Landau, Lev Davidovich

(lyĕf dəvē`dəvĭch ləndou`), 1908–68, Soviet physicist, b. Baku, Azerbaijan. A child prodigy in mathematics, he entered Baku Univ. at 14; at 21 he received a doctorate from the Univ. of Leningrad. In 1934 he worked with Niels Bohr in Copenhagen. In 1937 he became head of the theoretical department of the USSR Academy of Sciences. A key figure in Soviet space technology, he helped make the first Soviet atomic bomb.
