11824 Alpaidze           Discovered 1982 Sept. 16 by L. I. Chernykh at the Crimean Astrophysical Observatory.
Galaktion Eliseevich Alpaidze (1916-2006) was chief of the cosmodrome in Plesetsk from 1963 to 1975. Under his leadership the cosmodrome was developed for testing space vehicles, and it became the most active launch site in the world.
