Mary Zimbalist : Biography :  Nurse and Activist

When World War II broke out, she left acting to work full time as a nurse’s aid for the Red Cross. Mary and Sam were politically active in many movements, including fighting the Hollywood Black List and McCarthyism in the late 1940s and 1950s. They organized a delegation of famous people in the film industry to go to Washington and protest the McCarthy anti-American trials, despite all attempts by the studios to stop them.
