Granville Tailer Woods (April 23, 1856 – January 30, 1910) was an American inventor who held more than 50 patents in the United States.[1] He was the first African American mechanical and electrical engineer after the Civil War.[2] Self-taught, he concentrated most of his work on trains and streetcars. One of his inventions is the Synchronous Multiplex Railway Telegraph, a variation of the induction telegraph that relied on ambient static electricity from existing telegraph lines to send messages between train stations and moving trains.[3]
Granville T. Woods invented and patented Tunnel Construction for the electric railroad system, electrical rollercoasters and multiple newspapers referred to him as the "Black Edison".[4][5][6][7][8]
