Light Bulb History

Though Thomas Edison is credited with inventing the electric light bulb in 1879, many other inventors' contributions led to the culmination of Edison's light bulb, and advances to light bulb technology have been made almost continuously since then. Some of the other scientists who contributed to the eventual creation of the light bulb are Humphry Davy, James Lindsay, Warren de la Rue, Jean Eugene Robert-Houdin, and Heinrich Gobel.
