About
Leonard "Chico" Marx (March 22, 1887 – October 11, 1961) was an American comedian and film star as part of the Marx Brothers. His persona in the act was that of a dim-witted con artist, seemingly of rural Italian origin, who wore shabby clothes, and sported a curly-haired wig and Tyrolean hat.
