Historians Robert Friedel and Paul Israel list inventors of incandescent lamps prior to Joseph Swan and Thomas Edison of General Electric. [4]: 91–93 They conclude that Edison's version was the first practical implementation, able to outstrip the others because of a combination of four factors: an effective incandescent material; a vacuum higher than other implementations which was achieved ...
Sir Joseph Wilson Swan FRS (31 October 1828 – 27 May 1914) was an English physicist, chemist, and inventor.He is known as an independent early developer of a successful incandescent light bulb, and is the person responsible for developing and supplying the first incandescent lights used to illuminate homes and public buildings, including the Savoy Theatre, London, in 1881.
To avoid a possible court battle with yet another competitor, Joseph Swan, who held an 1880 British patent on a similar incandescent electric lamp, [69] he and Swan formed a joint company called Ediswan to manufacture and market the invention in Britain. The incandescent light bulb patented by Edison also began to gain widespread popularity in ...

In 1840, he enclosed a platinum coil in a vacuum tube and passed an electric current through it, thus creating one of the world's first electric light bulbs. [ 7 ] [ 8 ] [ 9 ] The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain ...
