Did Thomas Edison invent the light bulb?

Answer

Thomas Edison did not invent the light bulb, but he did invent the first practical incandescent light. Edison's invention improved upon previous models that were not capable of being used in the home. Edison is also credited with inventing the first electrical system capable of powering a light bulb long-term.

Technically, the first light bulb was invented by Humphrey Davy in 1806. Davy invented a bulb that was powered by a spark traveling between two charcoal rods. This invention was not practical for residential use, as it was too bright. The invention also required the use of batteries or another source of power. Edison's work expanded upon Davy's rudimentary light bulb, but many other inventors, such as Joseph Swan, also contributed to the creation of the first residential light bulb.
