Black History Moment: Frederick McKinley Jones (1893-1961)
Frederick McKinley Jones left his mark with the development of refrigeration equipment, receiving over 40 patents for it. In the 1930s, he began inventing automatic refrigerated air-cooling units for trucks, trains, ships, and planes, which helped the preservation of food. His creation, the Thermo King, allowed people to eat fresh food year-round. His work also contributed to the preservation of blood and medicine, proving to be particularly useful during WWII. In 1991, he became the first African American to receive the National Medal of Technology.
