On this day in 1940, Frederick McKinley Jones receives a patent for an air conditioning unit for trucks, helping to change long-haul carriage of food and blood. His invention altered American society’s eating habits, so that people could eat fresh food throughout the United States, especially during the summer and winter seasons. The air-conditioning unit also branched out to the military field hospitals and military field kitchens. Today, Jones is celebrated as the most creative African American inventor of our time. #patent #frederickmckinleyjones #USPTO #omnilegalgroup
