The Marx Brothers were an American comedy troupe who achieved success in vaudeville, on Broadway, and in 13 motion pictures. The five brothers were Chico Marx, Harpo Marx, Groucho Marx, Gummo Marx, and Zeppo Marx, though Gummo and Zeppo both left the group over time, leaving Chico, Harpo, and Groucho as a trio. They are considered by critics, scholars and fans to be among the greatest and most influential comedians of the 20th century, a recognition underscored by the American Film Institute (AFI) selecting five of their thirteen feature films to be among the top 100 comedy films and including them as the only group of performers on AFI's 100 Years...100 Stars list of the 25 greatest male stars of Classical Hollywood cinema.
