She designed over 200 Broadway shows for Martha Graham, New York City Ballet, and the Metropolitan Opera. She also brought to Broadway such famous musicals as West Side Story (1957), The Sound of Music (1959), A Funny Thing Happened on the Way to the Forum (1962), Fiddler on the Roof (1964), Hello Dolly! (1964), and Cabaret (1966).
