Julius Henry Marx (October 2, 1890 – August 19, 1977), known professionally as Groucho Marx, was an American comedian and film and television star. He was known as a master of quick wit and is widely considered one of the best comedians of the modern era. His rapid-fire, often impromptu delivery of innuendo-laden patter earned him many admirers and imitators.

Arthur Duer Marx (born Adolph Marx; November 23, 1888 – September 28, 1964), known professionally as Harpo Marx, was an American comedian, actor, 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 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). He frequently used props such as a horn cane, made up of a lead pipe, tape, and a bulbhorn, and he played the harp in most of his films.
