Chico Marx Biography
As a kid trying to negotiate his way through various gang territories to a floating crap game or a new pool hall where he was not yet known as a hustler, Leonard (Chico) Marx learned to fake several accents. Because he later employed an Italian accent in the Marx Brothers' act, people assumed his name was pronounced "Cheeko." Instead, Leonard was dubbed "Chicko" for his other consuming passion, women (or "chicks"), at which he was more successful than gambling, but when a typesetter dropped the "k" out of his name, the brothers let it stay as Chico. Chico was the brother who guided the Marxes to stardom. He took over the act's managment (amicably) from their mother, Minnie, and through audacity and charm, Chico secured the Brothers their first international (London) booking, their first Broadway show and their MGM contract with
Irving Thalberg, among other successes.

Trivia

Brother of Groucho Marx, Harpo Marx, Zeppo Marx, and Gummo Marx.

Brother-in-law of Barbara Marx, Ruth Johnson, Eden Hartford, Susan Fleming, and Kay Marvis.

Was an avid poker player and is rumored to have had a photographic memory so good, he could memorize the positions of cards in a deck. When a check written by Chico was found in mobster Bugsy Siegel's wallet at the time of his death, Chico was interrogated by police. He insisted the check was payment of a gambling debt from a poker game. When asked about his knowledge of Siegel's criminal activities, Chico stated, "We never discussed business." Groucho Marx later said of this incident, "Chico was lucky that Bugsy was shot. If Bugsy had tried to cash that check, it would have bounced. Then Bugsy would have shot Chico."

Son of Sam Marx and Minnie Palmer.

Father-in-law of Shamus Culhane.

Unmade-up and out of costume, the resemblance between Chico and his brother Harpo Marx was extraordinary. On the TV game show "I've Got a Secret" (1952), Chico once appeared in Harpo's wig and costume, with the "secret" "I'm Pretending To Be Harpo Marx (I'm Chico)" and fooled all the panelists - including Groucho Marx.

He was portrayed by actor Irwin Pearl in the Broadway show "Minnie's Boys," which ran an at the Imperial Theatre for 80 Performances from Mar 26 to May 30, 1970.

Great-uncle of Jade Marx-Berti, Gregg Marx, Laura Guzik, and Brett Marx.

While filming Horse Feathers, he got into a bad accident, shattering his knee. In some scenes, you can see him limp.

He and Harpo were usually mistaken as twins when they were young.

W.C. Fields said that The Marx Brothers were the only act he couldn't follow on the live stage. He is known to have appeared on the same bill with them only once, during an engagement at Keith's Orpheum Theatre in Columbus, OH, in January 1915. At the time the Marx Brothers were touring "Home Again", and it didn't take Fields long to realize how his quiet comedy juggling act was faring against the anarchy of the Marxes. Fields later wrote of the engagement (and the Marxes), "They sang, danced, played harp and kidded in zany style. Never saw so much nepotism or such hilarious laughter in one act in my life. The only act I could never follow . . . I told the manager I broke my wrist and quit.".
