Anytime you see a truck on the highway transporting refrigerated or frozen food, you're seeing the work of Frederick McKinley Jones.

One of the most prolific Black inventors ever, Jones patented more than 60 inventions in his lifetime. While more than 40 of those patents were in the field of refrigeration, Jones is most famous for inventing an automatic refrigeration system for long haul trucks and railroad cars.

Before Jones' invention, the only way to keep food cool in trucks was to load them with ice. Jones was inspired to invent the system after talking with a truck driver who lost his whole cargo of chicken because he couldn't reach his destination before the ice melted. As a solution, the African-American inventor developed a roof-mounted cooling system to make sure food stayed fresh.

In addition to that refrigerator invention, Jones also invented an air-conditioning unit for military field hospitals, a refrigerator for military field kitchens, a self-starting gas engine, a series of devices for movie projectors and box-office equipment that gave tickets and made change. Jones was posthumously awarded the National Medal of Technology in 1991 – the first Black inventor to ever receive such an honor.
