Sidney Aaron "Paddy" Chayefsky (January 29, 1923 – August 1, 1981), was an American playwright, screenwriter, and novelist. He is the only person to have won three solo Academy Awards for Best Screenplay.
He was considered one of the most renowned dramatists of the so-called Golden Age of Television. His intimate, realistic scripts helped determine the naturalistic style of television drama of the 1950s, and he was regarded as the central figure in the "kitchen sink realism" movement of American television.
Martin Gottfried wrote, "He was a successful writer, the most successful graduate of television's slice of life school of naturalism."
