Mary Louise Comingore (August 24, 1913 – December 30, 1971), known professionally as Dorothy Comingore, was an American film actress. She starred as Susan Alexander Kane in Citizen Kane (1941), the critically acclaimed debut film of Orson Welles. In earlier films she was credited as Linda Winters, and she had appeared on the stage as Kay Winters. Her career ended when she was caught up in the Hollywood blacklist. She declined to answer questions when she was called before the House Un-American Activities Committee in 1952. Early years Margaret Louise Comingore was born in Los Angeles, California and was described as "a one-time Oakland school girl." She attended the University of California, Berkeley. Her father was an electrotyper; her sister Lucille operated a nightclub in San Francisco. From 1934 to 1940, Comingore was billed in her stage appearances as Kay Winters and then Linda Winters as a film actress. Film Dorothy Comingore was discovered by Charles Chaplin when she was acting in a small playhouse in Carmel. Whether Chaplin played any role in her career is questionable. In 1938, Comingore denied being Chaplin's protégé and indicated that press reports had exaggerated the limited contact that she had with Chaplin and one of his assistants. Comingore played bit parts in Hollywood movies until Orson Welles cast her as Susan Alexander, the second wife of press tycoon Charles Foster Kane, in his debut feature film Citizen Kane (1941). Her performance garnered rave reviews: “(She) is put through a range of emotions that would try any actress one could name,” wrote The Hollywood Reporter. Comingore's supposed Communist connections played a role in a legal battle for custody of her two children with Richard J. Collins. Although Collins was a member of the Communist Party, he later asked to appear before the House Un-American Activities Committee and revealed the names of communist colleagues. As a result, he was favored in the custody battle. According to Peter Bogdanovich in his DVD commentary on Citizen Kane, she impaired her subsequent career by turning down too many roles that she felt were uninteresting. She appeared in the film version of the Eugene O'Neill play The Hairy Ape (1944) with William Bendix, Susan Hayward and John Loder. Comingore's last movie appearance was in a supporting role in The Big Night (1951) starring John Drew Barrymore. Her career ended in 1951, when she was caught up in the Hollywood
