Born in New York City, Rose Hobart responded to the lure of the theater at a young age, went on stage at 15, then drifted to Hollywood and embarked on a movie career. Hobart film-debuted in the 1930 Fox version of "Liliom" and went on to appear in over 40 additional films, both in the A and B category. But by the late 1940s, her political views and pro-union stance caused her to be blacklisted. After a period of inactivity, she returned to acting in the 1960s on TV's Peyton Place (1964). For many years she resided at the Motion Picture and Television Country House, not far from Hollywood, where she enjoyed editing the House Newsletter.
