Black History Spotlight: Pioneers of Safety and Innovation

Garrett Morgan – The Safety Innovator

Garrett Morgan was a problem-solver whose inventions continue to save lives. Born in 1877 in Kentucky to formerly enslaved parents, Morgan had only a sixth-grade education but an insatiable curiosity that led him to become a prolific inventor.

One of his most famous inventions was the three-position traffic signal, which introduced the yellow light as a way to warn drivers before stopping. Before this, traffic signals only had two options—stop and go—which led to frequent accidents. Morgan’s design created a smoother flow of traffic and was eventually adopted worldwide. He sold the rights to General Electric for $40,000, an impressive sum at the time.

But his contributions didn’t stop there. In 1912, he developed the "safety hood," an early version of the gas mask that protected firefighters and workers from inhaling dangerous smoke and fumes. This invention proved its worth in 1916 when Morgan used it to rescue men trapped in a toxic tunnel explosion in Cleveland. Despite his life-saving actions, he rarely received recognition due to racism.

Morgan’s legacy is one of perseverance, innovation, and lasting impact. The next time you stop at a traffic light, take a moment to appreciate his work!

Frederick McKinley Jones – The Cold Chain Hero

If you've ever enjoyed fresh produce from across the country, received a temperature-sensitive vaccine, or even had ice cream shipped to your doorstep, you owe a debt of gratitude to Frederick McKinley Jones.

Born in 1893 in Cincinnati, Ohio, Jones was largely self-taught. He had a natural talent for engineering, which led him to develop one of the most important inventions in logistics history—the first automatic refrigeration system for trucks and trains in the 1930s. Before his invention, food and medical supplies would often spoil before reaching their destination. His revolutionary design allowed perishable goods to be transported long distances, transforming industries such as agriculture, medicine, and military logistics.

Jones co-founded Thermo King, a company that became a leader in refrigerated transport, ensuring that vaccines, blood, and even organs could be safely transported—a contribution that remains crucial to this day. He went on to secure over 60 patents, with many focused on refrigeration and automotive technology.

His contributions earned him the National Medal of Technology in 1991, making him the first Black American to receive the prestigious award. Jones’ work continues to have a massive impact on global trade, healthcare, and food distribution.

The next time you pick up fresh fruit from another state or receive a chilled delivery, remember the brilliant mind of Frederick McKinley Jones!
