Who invented the light bulb?

Thomas Edison is widely credited with the invention of the light bulb due to his significant contributions to its development and commercialization in the late 19th century. Although various inventors, including Sir Humphry Davy and Joseph Swan, created early forms of electric light, Edison's design in 1879 was the first practical and long-lasting incandescent light bulb. His improvements included a better filament and a vacuum-sealed glass bulb, which drastically enhanced its efficiency and durability. Edison's efforts not only made the light bulb functional for everyday use but also led to the establishment of electrical power distribution systems, paving the way for widespread electrification. This solidified his reputation as the key figure in the history of electric lighting.
