Forgotten Phonograph-Gadget Inventors: Louis Devineau

Louis Devineau surfaced in Cleveland in the late 1890s as a French instructor, and by the early 1900s he was working for the Federal Manufacturing Company, a Cleveland automobile-chassis manufacturer. He was also patenting some interesting after-market accessories for the phonograph, beginning with a folding horn in 1905. His light-weight self-supporting horn was first advertised for sale in September 1907:

Devineau eventually endeared himself to some local  politicians, and by 1908 he was serving as secretary of the Cleveland Sinking Fund Commission, which he apparently treated as his private treasury. In February 1909, a $12,840 shortage was discovered, with Devineau nowhere to be found. The papers reported that he had last been heard from in Belgium. A warrant was issued for his arrest on embezzlement charges, but nothing more was reported.
