This bio-bibliography was designed to present a combined biographical, critical and bibliographical portrait of the Marx Brothers. It examines their significance in film comedy in particular and as popular cultural figures in general. The book is divided into five chapters. It begins with a biography which explores the public and private sides of the Marx Brothers. Gehring focuses on the best-known of the Brothers, Groucho, Chico and Harpo, with special emphasis on Groucho. Groucho predominates for several reasons - he appears to have been the public’s favourite; he was the only brother to have a successful solo career; he produced a large body of writing, including eight books and volumes of correspondence; and he was the only brother to participate in the Marx Brothers revival of the 1960s and 1970s.
