Russian-US dancer and teacher. She studied at the Imperial Ballet School with Fokine and graduated into the Mariinsky in 1906 where she danced until 1914. In 1909 her delicate beauty and musical technique brought her to the attention of Diaghilev and she danced several seasons with his company until 1914. She created the roles of Estrella in Fokine's Carnaval (1910), Street Dancer in his Petrushka (1911), and Papillon in his Les Papillons (1914), as well as one of the women tennis players in Nijinsky's Jeux (1913). During the war she nursed with the Red Cross then in 1917 returned to Russia where she again danced at the Mariinsky. In 1921 she married dancer Anatole Vilzak and they both returned to Diaghilev's company (1921–5). She was dismissed for sympathizing with striking dancers, and she and Vilzak went to dance at the Teatro Colón, Buenos Aires (1926–7). She subsequently danced in the companies of Rubinstein and Nijinska and also in the Karsavina-Vilzak Company. In 1936 she and Vilzak settled in America and between 1940 and 1946 ran their own ballet school in New York. She also taught at the School of American Ballet from 1936, Ballet Theatre School (1951–3), Washington School of Ballet (1963–5), and at the San Francisco Ballet School from 1965.
