Leonid Snezhko (1940–2011) was a Russian astrophysicist. He first proposed the idea of role reversal in close binary systems, modeled the atmospheres of hot stars and studied stellar winds. Leonid specialized in telescope optical systems, and oversaw the development of large telescopes in Bulgaria and Georgia.Naming citation (WGSBN Bull. 5, #27, 9), IAU / Minor Planet Center, via NASA/JPL
