Boris Borisovich Yegorov (November 26, 1937 – September 12, 1994) was a Soviet physician-cosmonaut who became the first physician to make a space flight.
Yegorov came from a medical background, with his father a prominent heart surgeon, and his mother an ophthalmologist. He also selected medicine as a career and graduated from the “First Moscow Medical Institute” in 1961. During the course of his studies, he came into contact with Yuri Gagarin’s training and became interested in space medicine. The asteroid 8450 Egorov is named in his honor.
