19919 Pogorelov           Discovered 1977 Oct. 8 by L. I. Chernykh at the Crimean Astrophysical Observatory.
Aleksey Vasil'evich Pogorelov (1919-2002), a Ukrainian Soviet mathematician, was responsible for the solution of a number of key problems in geometry "as a whole", in the fundamentals of geometry, in the theory of the Monge-Ampère equation and in the geometrical theory of thin elastic shells.
