Jerry Lewis, the legendary character and physical comedian, has died, his talent agency said Sunday. He was 91.

The multi-faceted star was arguably best known as the funnier half of slapstick comedy duo Martin and Lewis, which he formed with singer Dean Martin. The two talents began their partnership at the legendary 500 Club in Atlantic City in 1946 before hitting the big time at New York City's Copacabana Club.

But the popular entertainer also enjoyed a long film and stage career after he split with Martin in 1956, writing and directing acting in many hit movies through the 1950s, 60s and 70s, including "The Nutty Professor," "The Bellboy" and "The Ladies Man."

Lewis was a well known activist for muscular dystrophy funding — hosting his famous MDA telethon from 1966 until 2010 — as well as raising money for children's issues.
