        African-American Inventors | Georgia Stories


        Chris Mitchell teaches Georgia students about African American inventors using original patents, documents, and photographs. Among African American inventors she recognizes are Garrett Morgan from Cleveland, Ohio who designed the traffic signal we see every day. Lewis Latimer proposed the use of the carbon filament for light bulbs that allowed them to burn longer. He was hired by and was the only African American in Thomas Edison’s laboratory. Frederick McKinley Jones holds 60 patents. He designed the technology that adapted silent movie projectors and allowed them to show talking movies. His invention of the refrigerated truck allows fruits and vegetables to remain fresh when they are shipped across the country.
