Lewis Latimer (1848 - 1928)
Born in Chelsea Massachusetts, Latimer enlisted in the army at 15 years of age. After the Civil War, he taught himself mechanical drawing while working at a patent law film. It was there that he patented a carbon filament for the incandescent lightbulb in 1881. This would make electric lighting more affordable and more common in households. He also worked for Thomas Edison and drafted the drawings that Alexander Graham Bell would later on use to patent the telephone in 1876.
