Granville T. Woods also known as the "Black Edison"

 



Granville T. Woods

April 23, 1856 - January 30, 1910

Granville was born in Columbus, Ohio on April 23, 1856. He had a scarce education. When he was a teenager, Granville had several different jobs within the railroad industry. At about age 20-22, while living in New York City he attended school for engineering and electricity. Working at pumping stations and shifting cars he had to travel between companies which lead to the creation of inductor telegraph. In 1889, Granville filed for his first patent which improved steam boiler furnaces.


Alexander Graham Bell bought Granville's patent which merged the telephone and telegraph. In 1887, Granville invented the multiplex telegraph which allowed men voice communication enhancing faster delivery of important information stopping significant mistakes like train accidents. Granville was known as the "Black Edison" because Thomas Edison filed a lawsuit scrutinizing Granville's patent. Granville beat it. Thomas wanted to be a collaborator and Granville turned him down. Many of Granville T. Woods' inventions were distributed to major manufacturers of electrical equipment which is being used in today's society.
