Grinberg, Georgii Abramovich 

Born June 3 (16), 1900, in St. Petersburg. Soviet physicist; corresponding member of the Academy of Sciences of the USSR (1946). Graduated from the Petrograd Polytechnical Institute in 1923. From 1919 to 1930 he worked in the State X-ray and Radiology Institute and the Physicotechnical Institute (Leningrad) that was created from it. He was a staff member of the Leningrad Electrophysical Institute from 1930 to 1936 and, from 1929 to 1941, was simultaneously on the staff of the Svetlana plant. He taught at the Leningrad Polytechnical Institute from 1924 to 1955 (he became a professor in 1930). Since 1941 he has worked in the Physicotechnical Institute of the Academy of Sciences of the USSR.

Grinberg’s main work is on theoretical electronics, the theory of the propagation of electromagnetic waves, mathematical physics, and the theory of elasticity. In 1942 and 1943 he developed a general theory of the focusing effect of electrical and magnetic fields. He proposed a theory of coastal refraction and studied the problem of the propagation of radio waves in a nonuniform atmosphere and developed methods for solving a number of problems of mathematical physics. Grinberg was awarded the State Prize of the USSR in 1949 for his work Selected Problems in the Mathematical Theory of Electrical and Magnetic Phenomena (1948). He has been awarded the Order of Lenin and the Order of the Red Banner of Labor.
