(b Miami, 27 Oct. 1942)
US dancer, ballet mistress, and director. She studied with Georges Milenoff, at the National Ballet School of Canada, and at the School of American Ballet. In 1960 she joined New York City Ballet, where her exceptional height, speed and attack proved ideal for the Balanchine style. In 1962 she was appointed a soloist, but although she performed almost all the ballerina roles in the Balanchine repertoire, he created only two roles for her, in Raymonda Variations (1961) and Jewels (1967). In 1968 she left New York City Ballet, embarking on a peripatetic career in Europe as ballet mistress, director, and stager of Balanchine ballets. A tireless ambassador for the latter's work, she has mounted more than twenty of his ballets in numerous productions worldwide. She was ballet mistress of the Berlin Opera Ballet (1971–3), director of Geneva Ballet (1973–8) and Zurich Ballet (1978–85), and ballet director of La Scala in Milan (1986–7). She was also artistic director of Ballet British Columbia (1989–90), for whom she choreographed Variations concertantes (mus. Ginastera, 1990). Since 1988 she has worked for the Balanchine Trust.
