Carbon Light Bulb Filament, Invented by Lewis Latimer in 1881

The light bulb itself was invented by Thomas Edison, but the innovation used to create longer-lasting light bulbs with a carbon filament came from African-American inventor Lewis Latimer. Latimer, the son of runaway slaves, began work in a patent law firm after serving in the military for the Union during the Civil War. He was recognised for his talent drafting patents and was promoted to head drafts-man, where he co-invented an improved bathroom for railroad trains.
