Thomas Edison is usually credited with the invention of the light bulb, but the famous American inventor wasn't the only one who contributed to the development of this revolutionary technology.
Who Invented The Incandescent Light Bulb? It wasnât Thomas Edison. What Edison did was improve on the design in a patent he purchased from two earlier inventors, Henry Woodward and Matthew Evans.
