Garrett Augustus Morgan Sr. (March 4, 1877 – July 27, 1963) was an American inventor, businessman, and community leader.His most notable inventions were a type of three-way traffic light, [1] and a protective 'smoke hood' [2] notably used in a 1916 tunnel construction disaster rescue.
The signal was 22 feet (6.7 m) high. The light was called the semaphore and had arms that would extend horizontally that commanded drivers to "Stop" and then the arms would lower to a 45 degrees angle to tell drivers to proceed with "Caution".
