Rodney Stephen Steiger ( STY-gər; April 14, 1925 – July 9, 2002) was an American actor, noted for his portrayal of offbeat, often volatile and crazed characters. Ranked as "one of Hollywood's most charismatic and dynamic stars", he is closely associated with the art of method acting, embodying the characters he played, which at times led to clashes with directors and co-stars. He starred as Marlon Brando's mobster brother Charley in On the Waterfront (1954), the title character Sol Nazerman in The Pawnbroker (1964) which won him the Silver Bear for Best Actor, and as police chief Bill Gillespie opposite Sidney Poitier in the film In the Heat of the Night (1967) which won him the Academy Award for Best Actor.
Steiger was born in Westhampton, New York, the son of a vaudevillian. He had a difficult childhood, running away from home to escape an alcoholic mother at the age of 16. After serving in the South Pacific during World War II, he began his acting career with television roles in 1947, and went on to garner critical acclaim for his portrayal of the main character in the teleplay "Marty" (1953).
