Who is Marx Brothers from The Theater and Its Double and what is their importance?

The Marx Brothers were siblings born in New York the late 19th century to Jewish parents of German origins. The brothers teamed up to become stage comedians before eventually developing a successful career in Hollywood as movie actors. They owe much of their success to their strange sense of humor, which used unpredictable language associations and dissociations in order to shock the public. In The Theater and its Double, Antonin Artaud refers to two of the Marx Brothers movies: "Animal Crackers" and "Monkey Business."
