That fresh produce in your fridge? It’s there because of Frederick Jones’ mobile refrigeration unit, invented in 1938. Before that, transporting perishable food across the country was nearly impossible.Born in 1893, Jones left school in 8th grade but went on to earn an engineering license by age 20. His natural talent for mechanics led him to create over 60 patents, with 40 focused on refrigeration alone.
During WWII, his portable cooling systems became vital for preserving blood, medicine, and food for troops. His company, Thermo King Corporation, still powers refrigerated trucks across America’s highways today
