<P> Bogart began acting in 1921 after a hitch in the U.S. Navy in World War I and little success in various jobs in finance and the production side of the theater . Gradually he became a regular in Broadway shows in the 1920s and 1930s . When the stock market crash of 1929 reduced the demand for plays, Bogart turned to film . His first great success 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). </P> <P> Bogart's breakthrough as a leading man came in 1941 with High Sierra and The Maltese Falcon . The next year, his performance in Casablanca (1943; Oscar nomination) raised him to the peak of his profession and, at the same time, cemented his trademark film persona, that of the hard - boiled cynic who ultimately shows his noble side . Other successes followed, including To Have and Have Not (1944), The Big Sleep (1946), Dark Passage (1947), and Key Largo (1948), all four with his wife Lauren Bacall; The Treasure of the Sierra Madre (1948); In a Lonely Place (1950); The African Queen (1951; Oscar winner); Sabrina (1954); The Caine Mutiny (1954; Oscar nomination); and We're No Angels (1955). His last film was The Harder They Fall (1956). </P> <P> During a film career of almost 30 years, Bogart appeared in more than 75 feature films .

Belmont was the only child of the unhappy marriage of Adam Watkins Bogart, a Canandaigua, New York innkeeper, and his wife, Julia, a wealthy heiress .

Belmont and Maud married in June 1898; he was a Presbyterian, of English and Dutch descent, and she was an Episcopalian of English heritage, and a descendant of Mayflower passenger John Howland . Young Humphrey was raised in the Episcopal faith, but was non-practicing for most of his adult life . </P>
