Actor. Widely regarded as an American culture icon, he is best remembered for his legendary films "High Sierra" (1941, with Ida Lupino), "The Maltese Falcon" (1941, with Mary Astor), "Casablanca" (1942, with Ingrid Bergman), "The Treasure of the Sierra Madre" (1948, with Walter Huston), "The African Queen" (1951, with Katharine Hepburn, for which he won his only Academy Award for Best Actor), and "The Caine Mutiny" (1954, with Jose Ferrer). In 1944, he starred in "To Have and Have Not" with Lauren Bacall, who became his fourth wife. A famous line from the movie, delivered by Bacall to Bogart, was, "If you need anything, just whistle." So when Bogart died in 1957, Bacall placed a whistle inscribed with the line inside the silver urn with his ashes.
