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 had already got a patent for the bulb though, and sued Eddison for the patent rights.After that, the pair worked together and merged companies. 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.
