1890-1950. Russian dancer and choreographer. Noted for his powerful but graceful technique, he was a legendary member of Diaghilev's Ballets Russes, for whom he choreographed Debussy's Prelude a l'Apres-midi d'un faune 1912 and Jeux 1913, and Stravinsky's The Rite of Spring 1913. He also took lead roles in ballets such as Petrushka 1911. He rejected conventional forms of classical ballet in favour of free expression. His sister was the choreographer Bronislava Nijinska (1891-1972).
