Thomas Edison Lightbulb. Let there be Light! Historians agree that Thomas Edison was not the inventor of the electric light bulb, but he did produce the first commercially viable one.
In 1874 he got a patent for his invention . In 1893, the German inventor Heinrich GÃ¶bel claimed he had developed the first light bulb in 1854: a carbonised bamboo filament, in a vacuum bottle to prevent oxidation, and that in the following five years he developed what many call the first practical light bulb.
