Garrett Augustus Morgan, Sr.

Garrett Augustus Morgan, Sr. was an inventor, entrepreneur, and civic leader whose most important achievements were developed in Cleveland, Ohio, where his ingenuity helped save lives and reshape modern urban safety. Born in Kentucky to formerly enslaved parents, Morgan moved to Cleveland in the late 1890s. He began his career as a sewing machine repairman, but his curiosity and mechanical skill quickly led him to experiment with new ideas. In Cleveland, Morgan opened multiple businesses, including a sewing equipment repair shop and a tailoring company, employing dozens of workers and manufacturing clothing using machines he designed himself. Morgan’s experiences navigating Cleveland’s busy streets inspired his most famous invention: the three-position traffic signal. In 1923, he became the first person to receive a U.S. patent for a traffic signal that included a warning interval between “Stop” and “Go,” dramatically reducing intersection collisions. The invention laid the foundation for modern traffic control systems still used today. Morgan was also the inventor of a precursor to the modern gas mask. In 1916, during a deadly explosion in Cleveland’s Waterworks Tunnel, Morgan and his brother used his safety hood to rescue trapped workers after previous attempts had failed. Though initially denied recognition due to racial prejudice, Morgan’s heroism was later acknowledged by the city and nation. Cleveland stands as the city where Garrett Morgan transformed innovation into public safety, leaving a legacy that continues to protect lives around the world.
