A former model, the luminously beautiful Dorothy Hart was signed to a contract by Universal Pictures after having made only one film, Columbia's Gunfighters (1947). After that she did westerns, costume dramas, prison sagas, Tarzan movies, and the cult classic I Was a Communist for the F.B.I. (1951). However, she soon left the film business in 1952, moved to New York and did occasional guest spots on TV dramas and game shows. She was very active in working through the United Nations for the world's children.
