Oscar-winner Edmond O'Brien was one of the most respected character actors in American cinema, from his heyday of the mid-1940s through the late 1960s. Born on September 10, 1915, in the New York City borough of Brooklyn, O'Brien learned the craft of performance as a magician, reportedly tutored by neighbor Harry Houdini. He took part in student theatrics in high school and majored in drama at Fordham University, dropping out after six months. He made his Broadway debut at the age of 21 in 1936 and, later that year, played "The Gravedigger" in the great Shakespearean actor John Gielgud's legendary production of "Hamlet".
