2126 Gerasimovich           Discovered 1970 Aug. 30 by T. M. Smirnova at the Crimean Astrophysical Observatory.
Named in memory of Boris Petrovich Gerasimovich (1889-1937), professor at Kharkov University (1922-1931), then chief of the astrophysics section and from 1933 director of the Pulkovo Observatory. His scientific papers cover a large range of astrophysical problems, and he was a member of many scientific societies.
