1546 Izsak           Discovered 1941 Sept. 28 by G. Kulin at Budapest.
Named in memory of Imre Izsak (1929-1965), Hungarian-born astronomer and celestial mechanician, who made important contributions to the study of artificial-satellite motion. In his later years he worked at the Cincinnati Observatory and the Smithsonian Astrophysical Observatory.
