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.
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.
