Boris Yegorov

Boris Borisovich Yegorov (Russian: Борис Борисович Егоров; November 26, 1937, Moscow – September 12, 1994, Moscow) was a Soviet doctor-cosmonaut and the first physician in space.

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 had come into contact with Yuri Gagarin's training and had become interested in space medicine.

Yegorov was selected as a member of the multi-disciplinary team that flew on Voskhod 1. It has been suggested that his father's influence within the Politburo may have had some bearing on the selection. As a result of this space flight, Boris Yegorov was awarded the title of the Hero of the Soviet Union on October 19, 1964.

He eventually earned a doctorate in medicine, with his specialisation being the sense of balance.

He was married three times, had three children and died from a heart attack. Asteroid 8450 Yegorov is named in his honor.
