Garrett Morgan: Study the Danger, Then Build the Answer

Garrett Morgan was born in Paris, Kentucky, to parents who had been enslaved. He left home as a teenager and eventually settled in Cleveland, Ohio, working repairs on sewing machines — hands-on experience that shaped a lifelong instinct for figuring out how machines worked and where they failed.

In the years before World War I, Morgan developed a safety hood, a forerunner of the modern gas mask, and famously used it himself to help rescue trapped workers after a tunnel explosion beneath Lake Erie. He later turned that same problem-solving instinct to the streets: his early traffic signal introduced a stop-in-all-directions position, bringing order to intersections where cars, horse-drawn buggies, and pedestrians all competed for the same space.

What he left behind

• Developed a protective safety hood, a forerunner of the modern gas mask
• Used his invention to rescue trapped workers after a Lake Erie tunnel explosion
• Invented an early traffic signal featuring a stop-in-all-directions position, improving traffic control and pedestrian safety
• Founded a newspaper and supported educational institutions as part of his broader civic advocacy

Morgan's inventions answered the hazards of a rapidly industrializing, increasingly motorized America — dangerous job sites and chaotic city streets alike.
