On July 25, 1916, a massive explosion rocked the Cleveland Waterworks tunnel beneath Lake Erie, trapping dozens of workers in a toxic cloud of gas and debris. When the city’s rescue teams emerged from the tunnel overcome by fumes, officials turned to an unlikely savior: Garrett Morgan, a Black inventor whose “breathing device” had seemed like a novelty just two years earlier. That night, Morgan and his brother descended into the deadly tunnel wearing his gas masks, emerging with survivors and establishing Morgan as one of America’s most important safety innovators.
Born to former slaves in rural Kentucky in 1877, Garrett Augustus Morgan embodied the Great Migration’s promise of reinvention. With only an elementary education, he moved to Cleveland at age 14, where the city’s booming industrial economy offered opportunities unavailable in the agricultural South. Working as a sewing machine repairman, Morgan displayed the mechanical aptitude that would define his career, eventually opening his own tailoring shop and later a hair-straightening product company.
Cleveland in the early 1900s was a city transformed by rapid industrialization. The same factories, chemical plants, and underground infrastructure projects that created prosperity also generated unprecedented workplace hazards. Industrial accidents were routine, and toxic gas exposure claimed hundreds of lives annually in mines, tunnels, and factories across America. Morgan, observing these dangers firsthand, began developing what he called a “breathing device” in 1912—a hood connected by tubes to a clean air source near ground level.
The Cleveland tunnel rescue transformed Morgan from local entrepreneur to national figure, but it also revealed the racial barriers that constrained even the most talented Black inventors. Following the dramatic rescue, orders for Morgan’s “Safety Hood” poured in from fire departments and industrial companies nationwide. However, when customers discovered the inventor was Black, many orders were canceled. Morgan began employing white salesmen to demonstrate his device, sometimes pretending to be a Native American during presentations to avoid the full force of racial discrimination.
Despite these obstacles, Morgan’s gas mask proved indispensable during World War I, protecting thousands of soldiers from chlorine and phosgene gas attacks. The U.S. military purchased the devices in large quantities, though Morgan received little public credit for potentially saving countless American lives. His invention established the design principles still used in modern gas masks and respiratory equipment.
Morgan’s second major innovation emerged from Cleveland’s increasingly chaotic streets. As automobile ownership exploded in the 1920s, traffic accidents became epidemic. Existing traffic signals offered only “stop” and “go” positions, creating dangerous confusion during the transition periods. In 1923, Morgan patented a three-position traffic signal that included a “caution” phase, allowing vehicles to clear intersections safely. He sold the patent to General Electric for $40,000—equivalent to over $600,000 today—and his design became the standard for traffic management worldwide.
Garrett Morgan died in 1963, just as the Civil Rights Movement was dismantling the legal barriers that had constrained his career. His inventions had already saved countless lives and would continue doing so for generations. Every gas mask worn by firefighters, every traffic light managing urban intersections, traces its lineage to Morgan’s innovations born from Cleveland’s industrial crucible.
Morgan’s story illuminates how America’s greatest inventors often emerged from the nation’s most marginalized communities, transforming personal observations of social problems into universal solutions. His breathing device and traffic signal represent more than mechanical innovations—they embody the principle that safety and human life transcend racial boundaries, even when society itself refused to acknowledge that truth.
Like Morgan, the Wright Brothers exemplified Ohio's innovative spirit during America's age of mechanical breakthroughs and industrial transformation.
Provides essential context for Morgan's Cleveland, where industrial prosperity created both opportunities and the safety hazards he solved.
Explores how brilliant Black innovators like Morgan overcame systemic barriers to make breakthrough contributions to American progress.
