Massine was born into a musical family on 9 August 1895 in Moscow, Russia. His mother was a soprano in the Bolshoi Theater Chorus and his father played the French horn in the Bolshoi Theater Orchestra. Leonid was one of five children. He had three brothers, Mikhail, Gregori, and Konstantin – as well as one sister - Raissa. Due to their small age difference, Leonid and Konstantin were very close during childhood. Beginning when Leonid was seven, the Massine family spent most summers at their summer dacha in Zvenigorod-Moskovsky.
