Granville T. WoodsDied 30 Jan 1910 at age 53 (born 23 Apr 1856). American inventor who held numerous patents in diverse fields. As the most prolific black inventor by career of the late 19th and early 20th century in the U.S., he has been called the Black Edison. Wood's first patent (3 Jun 1884) was for a locomotive steam boiler. He started the Woods Electric Company, in Cincinnati, Ohio, to commercially develop a variety of electrical devices. In 1887 he patented his Synchronous Multiplex Railway Telegraph, which enabled moving railway trains to maintain communications links thus avoiding accidents. His other patents included a telephone transmitter, an electric railway, an electric incubator for hatching chickens (1900) and an important safety device - an automatic air-brake for railroad use (10 Jun 1902).« |
