Lebedev, Aleksei Borisovich
Born Dec. 17 (29), 1883, in Serdobsk, present-day Penza Oblast; died July 5, 1941, in Leningrad. Soviet electrical engineer; corresponding member of the Academy of Sciences of the USSR (1939).
After graduating from the St. Petersburg Polytechnic Institute in 1909, Lebedev taught at the institute; he became a professor in 1924. From 1930 to 1936 he was also a professor at the Moscow Institute of Power Engineering and, beginning in 1932, at the Leningrad Institute of Railroad Transportation Engineers. In 1914 he showed the feasibility of using direct current (3,000–5,000 volts) to electrify the railroads of the USSR (this was accomplished in 1931). In 1939 he headed work at the Academy of Sciences of the USSR on the development of new electric traction systems. His major works are concerned with the general theory of electric traction, methods of designing electrified railroads, the electrical design of overhead systems, and heat calculations for an electric traction motor under specific line operating conditions.
