Dorothy Hackett McGuire (June 14, 1916 – September 13, 2001) was an Academy Award-nominated American actress.
Born in Omaha, Nebraska, she began her acting career on the stage at the Omaha Community Playhouse. Eventually, she succeeded on Broadway, first appearing as an understudy to Martha Scott in Our Town, and subsequently starring in the domestic comedy, Claudia.
Brought to Hollywood by producer David O. Selznick on the strength of her stage performance, McGuire starred in her first film, a movie adaptation of her Broadway success, Claudia, and portrayed the character of a child bride who almost destroys her marriage through her selfishness. Her inaugural screen performance was popular with both the public and critics alike and was the catalyst for not only a sequel, Claudia and David (both movies co-starring Robert Young), but also for numerous other film roles.
