Humphrey DeForest Bogart (December 25, 1899 – January 14, 1957) was an American actor and is widely regarded as a cultural icon. In 1999, the American Film Institute ranked Bogart as the greatest male star in the history of American cinema. After trying various jobs, Bogart began acting in 1921 and became a regular in Broadway productions in the 1920s and 1930s. His first great success in film was as Duke Mantee in The Petrified Forest (1936), and this led to a period of typecasting as a gangster with films such as Angels with Dirty Faces (1938) and B-movies like The Return of Doctor X (1939). Bogart's breakthrough as a leading man came in 1941, with High Sierra and The Maltese Falcon.
