As part of Black History Month, we remember Garrett Augustus Morgan, a Cleveland inventor and businessman best known for creating the modern-day gas mask and traffic light. Morgan, the son of former slaves, was born March 4, 1877. He moved to Cleveland in 1895 and was employed as a sewing machine repairman for a clothing manufacturer.
The first manually operated gas-lit traffic light was installed in 1868 in London, though it was short-lived due to explosion. The first safe, automatic electric traffic lights were installed in the United States starting in the late 1890s.he first four-way, three-color traffic light was created by police officer William Potts in Detroit, Michigan in 1920. Ashville, Ohio claims to be the home of the oldest working traffic light in the United States, used at an intersection of public roads from 1932 to 1982 when it was moved to a local museum.
