About Bobby Mauch
William John Mauch (July 6, 1921 – September 29, 2006) and his identical twin brother, Robert Joseph Mauch (July 6, 1921 – October 15, 2007), were child actors in the 1930s. They had starring roles in the 1937 film The Prince and the Pauper, based on the 1881 novel of the same name by Mark Twain. == Early lives == Billy and Bobby were born in Peoria, Illinois, to Felix, an employee of the Toledo, Peoria and Western Railway and Marguerite Mauch, née Burley. Billy was older than Bobby by ten minutes. They began singing and acting in radio at the age of seven and later appeared in print advertisements before signing a contract with Warner Bros. == Careers == After moving with their mother to Hollywood in 1935, Billy was cast as the young title character in the film Anthony Adverse because he resembled Fredric March, who was to play Adverse as an adult. His brother Bobby was his stand-in for the role, but the brothers, whose voice and appearance were almost indistinguishable, later claimed that they had freely alternated who would play the part in the takes. They were cast as lookalikes in The Prince and the Pauper (1937), in which they co-starred with Errol Flynn and Claude Rains, and were each paid $350 per week. The picture earned them the cover story in the May 3, 1937 issue of Time. The twins went on to appear together in three films based on the Penrod stories by Booth Tarkington, but Bobby ended his acting career shortly afterwards.
