Discover the remarkable innovations of black inventors, whose ideas and inventions changed the course of history and continue to impact our world today.
Granville Woods was a very prolific inventor who came to be known as the "Black Edison". He made key contributions to the development of the telephone, streetcar, and more.
Woods received little schooling as a young man but later spent some time working on railways and took courses in engineering and electricity. He eventually set up his own company to develop and manufacture electrical apparatus. The patent for his improved telephone transmitter was bought byham Bell. One of his most important inventions was a grooved metal wheel that allowed streetcars to collect electric power from overhead wires.
However, his most important invention was the induction telegraph, which allowed communication by voice over telegraph wires. In 1901, Woods invented the power pick-up, which is the basis of the "third rail" used by electric-powered transit systems. At the time of his death, on January 30, 1910, Woods had received nearly 60 patents, and many of his inventions are still in use today.
