Dorothy Hackett McGuire was an 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, but also for numerous other film roles.
By 1943, at the age of 27, she was already playing mother roles, in such movies as A Tree Grows In Brooklyn. She was nominated for the Academy Award for Best Actress in 1947 for Gentleman's Agreement. Other notable films include Three Coins in the Fountain, Friendly Persuasion, Old Yeller, Swiss Family Robinson, The Greatest Story Ever Told, and The Dark At the Top of the Stairs'' .
