When did Thomas Edison make the light bulb?

The history of the Incandescent light bulb begins long before Edison, and his light bulb was NOT the original invention of the light bulb. In 1809 an English chemist named Humphry Davy invented the first electric light. A series of men followed, each creating their own version, and submitting patents. At the same time, Edison was working independently and eventually bought the patent rights from two of the other inventors. Then, in 1879, Thomas Alva Edison invented a carbon filament. It burned for forty hours, and this prototype would go on to become today's "light bulb".October 22, 1879
