Incandescent Electric Light Bulb
The Incandescent Lamp
If you are asking about the first light bulb it was Edison.
Sir Joseph Swann of England and Thomas Edison both developed workable electric incandescent lamps during the 1870s. Edison's lamp became the first commercially successful incandescent lamp (circa 1879). Edison received U.S. Patent 223,898 for his incandescent lamp in 1880.However, contrary to popular belief, Edison did not "invent" the first lightbulb, he improved upon a 50-year-old idea. Canadians Henry Woodward and Matthew Evans patented a light bulb in 1875, but could not raise the financing to commercialize their invention. Edison bought the rights to their patent
Swan invented the light bulb in 1878. Edison spent a year trying to improve it and filed a patent in the US a year later. The two men never met but decided to settle out of court and formed the Ediswan company

Thomas Edison did not invent the first light bulb. He did however improve on existing light bulbs by creating the first useable incandescent bulb.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.
