Julius Henry "Groucho" Marx (October 2, 1890 - August 19, 1977), was an American comedian and film star. He is famed as a master of wit. He made 15 feature films with his siblings, the Marx Brothers, and also had a successful solo career, most notably as the host of the radio and television game show, You Bet Your Life. He had a distinctive image, which included a heavy greasepaint moustache and eyebrows and glasses.

The bushy-browed, cigar-smoking wisecracker with the painted on mustache and stooped walk was the leader of The Marx Brothers. With one-liners that were many times full of sexual innuendo, Groucho never used profanity in any of his performances and said he never wanted to be known as a dirty comic. With a great love of music and singing (The Marx Brothers started as a singing group), one of the things Groucho was best known for was his rendition of the song "Lydia the Tattooed Lady."

From the late 1940s through 1961, he was the highly successful host of "You Bet Your Life" (1950) a quiz show on radio and television. His son, Arthur Marx, is a successful writer of biographies and TV scripts. Arthur complained about his father always being "on". If he asked Groucho about something serious or personal, Groucho would reply with one-liners.
