September 5, 1912 – With the addition of brother Leonard to the act the Four Marx Brothers give their first performance as a quartet at the Apollo Theatre in Chicago, Illinois. Their new show, Mr. Green’s Reception, is an expansion of their school act.
May 14, 1914 – The Four Marx Brothers open at the Gaiety Theatre in Galesburg, Illinois. During this three-day engagement they get their nicknames during a card game with comic Art Fisher.

They soon are back on the road with a new version of Home Again called ‘N’ Everything. Youngest brother Herbert, nicknamed Zeppo, replaces Gummo who joins the army.
