As a man who never had formal schooling to have his writings declared to be culturally important was a point of great satisfaction. Elton John accompanied Groucho to a performance of Jesus Christ Superstar. By the time the Marxes made their first movie they were major stars with sharply honed skills and when Groucho was relaunched to stardom on You Bet Your Life he had already been performing successfully for half a century.
He also had a successful solo career most notably as the host of the radio and television game show You Bet Your Life. He is known as a master of quick wit and widely considered one of the best comedians of the modern era. He made 13 feature films with his siblings the Marx Brothers of whom he was the third-born.
