Granville T. Woods' field shunting speed control syste Granville Tailer Woods (April 23, 1856 - January 30, 1910) was an inventor who held more than 60 patents in the U.S. He was the first African American mechanical and electrical engineer after the Civil War. Self-taught, he concentrated most of his work on trains and streetcars.One of his notable inventions was a device he called the Synchronous Multiplex Railway Telegraph, a variation of. The device was so successful that he later sold it to the American Bell Telephone Company. In 1887, Woods developed his most important invention to date - a device he called Synchronous Multiplex Railway Telegraph. A variation of the induction telegraph, it allowed for messages to be sent from moving trains and railway stations

On November 29,1887, Woods received a patent for his Induction Telegraph System, also called the Synchronous Multiplex Railway Telegraph. Communication between moving trains and between a moving train and a railroad station had previously been poor. In a telegraph system, a continuous wire must exist between a sending key and a receiving sounder Synchronous Multiplex Railway Telegraph Granville T. Woods was born in Columbus, Ohio on April 23, 1856, and attended school until age 10. After that, he attended night classes so he could apprentice in a machine and blacksmith shop during the day.
