He trained at the Imperial Theatre School in St Petersburg, graduating in 1900 into the Mariinsky Theatre company. In 1909 he was hired by Diaghilev as business manager and rehearsal director for the Ballets Russes Paris season; he stayed with the company until Diaghilev's death, the only member of the impresario's entourage to do so. As a dancer he created the role of Shah Shariar in Fokine's Scheherazade (1910), Guidone in Fokine's Le Coq d'or (1914), and the Russian Merchant in Massine's La Boutique fantasque (1919). When the Ballets Russes folded in 1929 he joined de Basil's Ballets Russes de Monte Carlo as chief regisseur, staying with that company until it, too, disbanded in 1948. Working with his wife, the dancer Lubov Tchernicheva, he produced several Fokine revivals for Sadler's Wells/Royal Ballet: Firebird (1954), Les Sylphides (1955), Petrushka (1957), and the Polovtsian Dances from Prince Igor (1965).
