The patent for the incandescent light bulb was granted to Thomas Edison on January 27, 1880. However, it's important to note that other inventors, including Sir Humphry Davy and Joseph Swan, had developed earlier versions of electric light. Edison's design improved upon existing technologies, leading to the practical and commercially viable light bulb.

Joseph Swan invented the first electric vacuum light bulb with a carbon fibre filament. About a year later, Thomas Eddison invented a similar bulb.

Swan later improved the filament used in the bulbs, though Eddison continued to use an inferior filament for a while. Eddison's company was eventually to become the USA's General Electric.The first electric light bulb however, as unpractical as it was, was invented by Humphry Davy in 1809.
