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.
After devising a commercially viable electric light bulb on October 21, 1879, Edison developed an electric "utility" to compete with the existing gas light utilities. [73] On December 17, 1880, he founded the Edison Illuminating Company, and during the 1880s, he patented a system for electricity distribution. The company established the first ...
Lewis Howard Latimer (September 4, 1848 – December 11, 1928) was an American inventor and patent draftsman. His inventions included an evaporative air conditioner, an improved process for manufacturing carbon filaments for electric light bulbs, and an improved toilet system for railroad cars.
Alessandro Cruto was an Italian inventor, born in the town of Piossasco, near Turin, who created an early incandescent light bulb.. Son of a construction foreman, he attended the school of architecture at the University of Turin, while also attending Physics and Chemistry lectures with the dream of crystallizing carbon to obtain diamonds.

The light bulb invented by Cruto lasted five hundred hours as opposed to the forty of Edison's original version. In 1882 Munich Electrical Exhibition in Bavaria, Germany Cruto's lamp was more efficient than the Edison's one and produced a better, white light.
Alexander Nikolayevich Lodygin, known after immigration to US as Alexandre de Lodyguine (Russian: Александр Николаевич Лодыгин; October 6, 1847 – March 16, 1923) was a Russian electrical engineer and inventor, one of the inventors of the incandescent light bulb.
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting . Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
The lamps on exhibition were incandescent light bulbs with carbon-filaments of high resistance, made of fibres of reed. [5] Two patents were granted to Heinrich Göbel in 1882: an improvement of the Geissler system of vacuum pumps, and a solution to connect carbon-filaments and metal-wires in a light bulb. [6] [7]
