The two younger brothers, Gummo and Zeppo, did not develop their stage characters to the same extent . They each left the act to pursue business careers at which they were successful, as well as a large theatrical agency for a time, through which they represented their brothers and others . Gummo was not in any of the movies; Zeppo appeared in the first five films in relatively straight (non-comedic) roles . The performing lives of the brothers were brought about by their mother Minnie Marx, who also acted as their manager . </P> <P> The Marx Brothers were born in New York City, the sons of Jewish emigrants from Germany and France . Their mother Miene "Minnie" Schoenberg (professionally known as Minnie Palmer, later the brothers' manager) was from Dornum in East Frisia, and their father Samuel ("Sam"; born "Simon"). Marx was a native of Alsace and worked as a tailor . (His name was changed to Samuel Marx, and he was nicknamed "Frenchy".)
