Spencer Bonaventure Tracy (April 5, 1900 – June 10, 1967) was an American actor, known for his natural performing style and versatility. One of the major stars of Hollywood's Golden Age, Tracy was the first actor to win two consecutive Academy Awards for Best Actor from nine nominations.

Tracy first discovered his talent for acting while attending Ripon College, and he later received a scholarship for the American Academy of Dramatic Arts. He spent seven years in the theatre, working in a succession of stock companies and intermittently on Broadway. His breakthrough came in 1930, when his lead performance in "The Last Mile" caught the attention of Hollywood. After a successful film debut in John Ford's "Up the River" (in which he starred with Humphrey Bogart), he was signed to a contract with Fox Film Corporation. Tracy's five years with Fox featured one acting tour de force after another that were usually ignored at the box office, and he remained largely unknown to movie audiences after 25 films, nearly all of them starring him as the leading man. None of them were hits, although his performance in "The Power and the Glory" (1933) was highly praised at the time.

During his career, Tracy appeared in 75 films and developed a reputation among his peers as one of the screen's greatest actors. In 1999, the American Film Institute ranked Tracy as the 9th greatest male star of Classic Hollywood Cinema.
