About Zeppo Marx
Herbert Manfred "Zeppo" Marx was an American comedic actor. He was the youngest, and last survivor, of the five Marx Brothers. He appeared in the first five Marx Brothers feature films from 1929 to 1933, usually performing in a more subdued style than his brothers and serving as a romantic lead and/or straight man. He abandoned acting for subsequent careers as an engineer and theatrical agent. Zeppo remained with the team in vaudeville, Broadway and the first five Marx Brothers films as the straight man and romantic lead until leaving the act following Duck Soup in 1933. In a rare television interview years later, Zeppo said that "Zep" was Italian-American slang for "baby", and the name fit as he was the youngest of the brothers.
