It depends on what you would classify as the actual invention of the light bulb. Humphry Davy first invented an electric light in 1800, which consisted mainly of a battery and carbon. In 1878, Sir Joseph Wilson Swan created new, longer-lasting electric lamps, which he showcased in England. Thomas Edison, after working with thousands of different prototypes, discovered the light bulb that could glow for over 1500 hours, laying the foundation for light bulbs today.
