Garrett Morgan (1875-1963), American inventor, whose two most important inventions were the three-way automatic traffic stop light and the gas mask (originally called a safety hood). He was born in Paris, Kentucky. Morgan started working at age 14 after 6 years of schooling. His interest in mechanics was sparked by a job as a sewing-machine adjustor for a clothing manufacturer.

The first four-way, three-colour traffic light was created by police officer William Potts in Detroit in 1920.[7] In 1923, Garrett Morgan patented a traffic signal device, although it was not a precursor of the modern traffic light
