Arthur “Harpo” Marx (born Adolph Marx; November 23, 1888 – September 28, 1964) was an American comedian, film star, mime artist and musician, and the second-oldest of the Marx Brothers.
In contrast to the mainly-verbal comedy of his brothers Groucho and Chico, Harpo’s comic style was exclusively visual, being an example of both clown and pantomime traditions. He wore a curly reddish blonde wig, and never spoke during performances (he blew a horn or whistled to communicate).
