Granville Woods Biography

Short Summary

Granville T. Woods was a pioneering African-American inventor and mechanical engineer who developed numerous innovations in the field of communication and electrical engineering during the late 19th and early 20th centuries. Often referred to as the “Black Edison,” he held over 50 patents, many of which significantly improved railway and telegraph systems.

Early Life & Education

Granville Woods was born on April 23, 1856, in Columbus, Ohio. Due to financial hardship, he left school at a young age and began working as an apprentice in mechanical engineering. Despite limited formal education, he continued to study engineering and electricity independently and gained hands-on experience working on railroads and in machine shops.

Career Highlights

Woods began filing patents in the 1880s, focusing primarily on electrical systems and communication devices. One of his most notable inventions was the “induction telegraph”, which allowed communication between moving trains and station operators — a major leap in railway safety. He also developed improved versions of the electric railway system, automatic brakes, and telephone transmitters.
