From their abandoned projects to how the brothers dealt with potential competitors, such as Buster Keaton, a wealth of information on lives and careers of all the brothers is organized in
this A-to-Z reference. Glenn Mitchell's latest findings are included as he continues to research the unique careers of Chico, Harpo, Groucho, Zeppo, Gummo—and Manfred. Vaudeville,
Broadway, and the classic films, including Cocoanuts, Duck Soup, and A Night at the Opera,are all covered in engrossing detail, as are the brothers' subsequent careers in
solo films, on stage, and in radio and television.
