Marx Brothers, team of American movie comedians. The members were Julius (1890?–1977), known as Groucho; Arthur (1888?–1964), originally Adolph and known as Harpo; Leonard (1887?–1961), known as Chico; and two other brothers, Milton (Gummo) and Herbert (Zeppo), who had both left the act by 1935; all were born in New York City. After starting in vaudeville they made a sensation on Broadway with The Cocoanuts and Animal Crackers, both of which they transferred to film (1929, 1930). Their anarchic, slapstick humor turned dignified settings into playhouses for Groucho's outrageous puns and wisecracks, Harpo's horn honking and girl chasing, and Chico's distorted logic. Zeppo appeared in their first five films as straight man. Their films include Monkey Business (1931), Horse Feathers (1932), Duck Soup (1933), and A Night at the Opera (1935). Groucho enjoyed a solo career as film actor, television game show emcee, and master raconteur in concert.
