He wasn’t a scientist. Not an engineer. Just a man with a wrench and a mind that wouldn’t quit.

In the 1930s, when most of the world believed refrigerated transport was impossible, Frederick McKinley Jones—a self-taught mechanic with only an 8th-grade education—was quietly changing history from his garage.

Born in 1893 in Cincinnati and orphaned by age nine, Jones grew up fixing cars, radios, and anything he could get his hands on. But it was in 1938 that he created something that would change how the world eats: the first automatic refrigeration system for trucks.

This wasn’t just a convenience—it was a revolution. His invention meant perishable goods could now be shipped safely across long distances, keeping food fresh and medicine viable. Hospitals, grocery chains, and farms were transformed forever.

And then came WWII. Jones’ invention became the backbone of the military food supply chain. His Thermo King system helped keep soldiers nourished on the front lines, saving lives with every convoy.

By the time he died in 1961, Jones had over 60 patents, and his legacy had reshaped global food systems—yet many still don’t know his name.

He didn’t have fancy degrees. He had drive.

If a man with an 8th-grade education could invent something that fed the world—what’s stopping you from changing yours?
