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.
The four-way traffic light, also known as the modern traffic signal, was invented by Garrett Morgan in 1923. Morgan was an African American inventor and entrepreneur who patented his design to help improve road safety and reduce traffic accidents.
The modern electric traffic light was invented by Garrett Morgan in 1923. He was an African-American inventor who improved upon previous designs by adding a caution indicator between the red and green lights.
