One of his notable inventions was the Multiplex Telegraph, a device that sent messages between train stations and moving trains. His work assured a safer and better public transportation system for the cities of the United States. ==Early life== According to some sources, Granville T. Woods was born to a mixed-race family in 1856; his mother's name was Martha J. Brown and his father's name was Cyrus Woods. He also had a brother named Lyates.〔Abiola Sinclair, "Black Man and the Railroad." (New York) Amsterdam News, February 23, 1991, p. 32.〕 His mother was part Indian (today referred to as Native American), and his father was black, or "Negro," as African-Americans were called back then.〔"Granville T. Woods, Electrician and Mechanical Engineer." Indianapolis (IN) Freeman, February 16, 1856, p. 1.〕 Granville attended school in Columbus until age 10, but had to leave due to his family's poverty, which necessitated his going to work;〔Dwayne A. Cotton, "Granville T. Woods: The Black Thomas Edison." Norfolk (VA) New Journal and Guide, July 17, 1985, p. 14.〕 he served an apprenticeship in a machine shop and learned the trades of machinist and blacksmith. Some sources of his day asserted that he also received two years of college-level training in "electrical and mechanical engineering," but little is known about where he might have studied.〔"Granville T. Woods, the First Colored Electrician."
