In 1838, Belgian lithographer Marcellin Jobard invented an incandescent light bulb with a vacuum atmosphere using a carbon filament. [17] In 1840, British scientist Warren De la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. The design was based on the concept that the high melting point of ...
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.

Henry Woodward was a Canadian inventor and a major pioneer in the development of the incandescent lamp. He was born in 1832. [1][2] On July 24, 1874, Woodward and his partner, Mathew Evans, a hotel keeper, filed a Canadian patent application on an electric light bulb. [2][3] It was granted on August 3, 1874, as Canadian patent number 3,738. [4]
Historian Thomas Hughes (1977) describes the features of Edison's method. In summary, they are: Hughes says, "In formulating problem-solving ideas, he was inventing; in developing inventions, his approach was akin to engineering; and in looking after financing and manufacturing and other post-invention and development activities, he was innovating."
