Lewis Howard Latimer (September 4, 1848 – December 11, 1928) was an African American inventor and patent draftsman. His inventions included an evaporative air conditioner, an improved process for manufacturing carbon filaments for light bulbs, and an improved toilet system for railroad cars. In 1884, he joined the Edison Electric Light Company where he worked as a draftsman.
Latimer's innovations in the design of carbon filaments, which were used in incandescent light bulbs, significantly improved the bulb's efficiency and made it more practical for everyday use. His contributions to the lighting industry helped make electric lighting more accessible and affordable.While Thomas Edison is often credited with inventing the practical incandescent light bulb, Latimer's contributions to its development were invaluable, and he played a crucial role in advancing the technology.
The Lewis H. Latimer House, his landmarked former residence, is located near the Latimer Projects at 34-41 137th Street in Flushing, Queens, New York City.
