Who was the first black man who made the traffic light?
In 1923, Garrett Augustus Morgan, Sr., an African American inventor, patented his own version of the traffic signal. The Morgan traffic signal was a non-electric, T-shaped pole unit that featured three hand-cranked positions: Stop, in all -directional stop position. This third position halted traffic in all directions to allow pedestrians to cross streets more safely. It was never practical enough to put into production. The story nevertheless has been widely and erroneously circulated that Morgan was the "inventor" of the traffic signal.
Did Garrett Morgan invented the traffic light?
Yes and no.African-American Garrett Morgan is credited with inventing the electric automatic traffic light which was based on semaphore. The system was quite different to another system invented by a Detroit police officer by the name of William Potts. He was the first to develop the first 4-way 3-colour light system, and it was installed in Detroit in 1920.However, both of these systems were preceded by traffic lights that were around even before cars. The very first traffic light in the world was located at a London intersection in 1868, and was a hand-held revolving gas lantern with red and green signals. This was not an entirely successful experiment, as the light exploded early in 1869, injuring the policeman who was operating it.

What did Garrett Morgan invent?
Garrett Morgan (U.S.A.) was an inventor and businessman from Cleveland who is best known for inventing a device called the Morgan Safety Hood and the gas mask in 1914. In 1923 he patented a traffic signal. I believe he also had a patent on a kind of sewing machine.Despite what some people may try to tell you, he did not "invent the traffic signal" ... he patented one kind of traffic signal; it wasn't the first, nor was it remarkably better than the many others that were being developed by many other people around the same time, and to the best of my knowledge no city ever actually used it.It's common for the traffic light myth to be trotted out during Black History Month, and it's unfortunate, because he really does deserve wider recognition for the safety hood that he not only developed but personally used in a heroic rescue of workers digging a water intake tunnel after a gas explosion and fire trapped them in there and killed the first people who tried to rescue them.
