Leonard Marx (March 22, 1887 – October 11, 1961), known professionally as Chico Marx, was an American comedian, musician, bandleader, actor and film star. He was a member of the Marx Brothers (Groucho Marx, Harpo Marx, and Zeppo Marx). His persona in the act was that of a charming, dim-witted albeit crafty con artist, seemingly of rural Italian origin, who wore shabby clothes and sported a curly-haired wig and Tyrolean hat. In virtually every film that includes the main trio of the Marx Brothers, Chico is seen working with Harpo Marx, usually as partners in crime. Leonard was the oldest of the Marx Brothers to live past early childhood (first-born Manfred Marx had died in infancy). In addition to his work as a performer, he played an important role in the management and development of the act in its early years.
He is also known as Leonard Marx.
Chico died of arteriosclerosis at age 74 on October 11, 1961, at his Hollywood home. He was the eldest brother and the first to die.
He is entombed in a crypt at Forest Lawn Memorial Park Cemetery in Glendale, California. Chico's younger brother Gummo is in a crypt across the hall from him.
