He was director of the Crimean Astrophysical Observatory from 1952–1987 and vice-president of the International Astronomical Union from 1964 to 1970.

After World War II, he was assigned to the Crimean Observatory, which was originally based in Simeiz, Crimea, on the Black Sea coast, and was then involved in the construction of a new observer in Naucine, in the Crimean Mountains.
