Early career and the Marx Brothers Zeppo replaced brother Gummo in the Marx Brothers' stage act when Gummo was drafted into the army in 1918. Zeppo had been employed as a mechanic for the
Ford Motor Company. He had no desire for a show business career, but Minnie Marx insisted that he replace Gummo because she wanted to maintain the act as a foursome. 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. He also appeared, without his brothers, performing a minor role in the
Adolphe Menjou comedy
A Kiss in the Dark (1925), billed as Herbert Marx. His performance was praised by the
New York Sun. Barbara Sinatra (Zeppo's second wife) said that he was considered too young to perform with his brothers, but when Gummo joined the army, Zeppo was asked to join the act as a last-minute replacement at a show in Texas. He and a Jewish friend were supposed to have a date with two Irish girls, but Zeppo canceled in order to board the train to Texas. His friend was shot several hours later by a gang that disapproved of Jews dating Irish girls. in 1932 Having watched his brothers for many years, Zeppo could imitate and replace any of the others when illness kept them from performing live on stage, most notably stepping in for Groucho during a tour of their greatest scenes when Groucho was recovering from
appendicitis. This tour took place around the release of the film
Animal Crackers. Groucho said: "He was so good as Captain Spaulding in
Animal Crackers that I would have let him play the part indefinitely if they had allowed me to smoke in the audience." However, Zeppo did not develop his own comic persona to play against those of his brothers. Critic Percy Hammond wrote in 1928: One of the handicaps to the thorough enjoyment of the Marx Brothers in their merry escapades is the plight of poor Zeppo Marx. While Groucho, Harpo, and Chico are hogging the show, as the phrase has it, their brother hides in an insignificant role, peeping out now and then to listen to plaudits in which he has no share. The popular assumption that Zeppo's character was superfluous was fueled in part by Groucho. According to Groucho's own story, when the group became the Three Marx Brothers, the studio wanted to trim their collective salary, and Groucho replied, "We're twice as funny without Zeppo!" Zeppo was mechanically adept and largely responsible for keeping the Marx family car running. He later owned Marman Products Co., which machined parts for the war effort during
World War II. The company produced a motorcycle called the
Marman Twin as well as the
Marman clamps used to hold the
atomic bombs inside the
B-29 bombers
Enola Gay and
Bockscar. He obtained patents for a wristwatch that monitored pulse rate and sounded an alarm if the heartbeat became irregular, and a therapeutic pad for delivering moist heat to a patient. The 2024 book by Robert S Bader
Zeppo: The Reluctant Marx Brother said that Zeppo was deeply associated with gangsters, and was called to testify before a
grand jury in 1958 about missing funds in a gambling syndicate. According to Bader his brothers were so worried about his associates and high-stakes gambling that they considered disowning him; but they were always personally close. After retiring from the screen, Zeppo founded a large theatrical agency with his brother Gummo and they represented numerous screenwriters and actors, including their brothers. ==Personal life==
