Born in 1856, his first successful paten led to some elements of the signal system currently on display at the New York Transit Museum.

It was so good that Thomas Edison tried to sue Woods and steal the concept -- but Edison lost in court.
"His reaction was to try and hire Granville Woods," Bryden said. "But Woods wanted to maintain his independence and turned him down."
Woods was a dynamic mechanical and electrical engineer who acquired more than 60 patents for everything from an egg incubator to what was the precursor to a crucial part of the subway system today -- the third rail.

As notable as that was, Bryden says Woods wasn't taken seriously because of the racial climate at the time and often had trouble selling his own ideas to railroads.
"He often had to resort to selling his ideas to more established inventors, which is quite often why he doesn't get the credit he was due," Bryden said.
