Eugene Gladstone O’Neill (1888–1953) was an American playwright. He had a varied profession as seaman, gold prospector, journalist, and actor before associating himself with experimental theatre in 1916. He won the Pulitzer Prize four times and the Nobel Prize for Literature in 1936.
Born in a hotel room in New York’s Broadway district, O’Neill was the son of James O’Neill, a matinee idol and one-time famous Shakespearean actor.
O’Neill won his first Pulitzer Prize for his first full-length play, Beyond the Horizon (1920.) Among his other notable plays are the monumental trilogy Mourning Becomes Electra (1931) and The Iceman Cometh (1946.)
O’Neill’s Long Day’s Journey into Night (1956) is considered a landmark in modern theater. This semi-autobiographical tragedy portrayed two mutually destructive family relationships and won O’Neill a posthumous Pulitzer Prize.
