Summary Thomas Edison is usually credited as the inventor of the lightbulb, but other inventors such as Alessandro Volta, Humphrey Davy, and Joseph Swan played a critical role in the development of this revolutionary technology. Davy's electric arc lamp was an improvement on Volta's stand-alone piles, but it still wasn't a very practical source of lighting. In 1850, English chemist Joseph Swan developed a lightbulb that used carbonized paper filaments in place of those made of platinum, but Edison patented the first commercially successful bulb in 1879.
