Who invented the traffic signal?
Garrett Morgan See website: http://inventors.about.com/library/inventors/blgas_mask.htm ---- The world's first traffic light was operating in London, England, even before cars were invented. It was a revolving gas-lit lantern with red and green signals, but in 1869, the light exploded, injuring the policeman who was operating it. In the early 1900s Garrett Morgan, an African-American living in Cleveland, Ohio, developed the electric automatic traffic light, originally based on a semaphore-system. Shortly after this, Detroit police officer William L Potts developed the first 4-way three colour traffic light using red, amber, and green railroad lights.

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.
