Joseph Swan, alongside Thomas Edison, is the person most credited with the invention of the light bulb. The Sunderland-born chemist created the first successful incandescent filament electric lamp and gave public demonstrations of it in late 1878 and early 1879.
In 1872, Russian Alexander Lodygin invented an incandescent light bulb and obtained a Russian patent in 1874. He used as a burner two carbon rods of diminished section in a glass receiver, hermetically sealed, and filled with nitrogen, electrically arranged so that the current could be passed to the second carbon when the first had been ...

The story of the lightbulb begins long before Edison patented the first commercially successful bulb in 1879. In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile. Made of alternating discs of zinc and copper— interspersed with layers of cardboard soaked in salt water — the pile...
In 1850, English chemist Joseph Swan began trying to make electrical light more economical, and by 1860 he had developed a lightbulb that used carbonized paper filaments in place of those made of platinum, according to the BBC. Swan received a patent in the U.K. in 1878, and in February 1879 he demonstrated a working lamp in a lecture in Newcastle,...
Where Edison surpassed his competition was in developing a practical and inexpensive lightbulb, according to the DOE. Edison and his team of researchers tested more than 3,000 designs for bulbs between 1878 and 1880. In Nov. 1879, Edison filed a patent for an electric lamp with a carbon filament, according to the National Archives.The patent listed...

Nov 22, 2013 · In 1835, the first constant electric light was demonstrated, and for the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament (the part of the bulb that produces light when heated by an electrical current) and the bulb’s atmosphere (whether air is vacuumed out of the bulb or it is filled with ...
Sir Joseph Wilson Swan (31 October 1828 – 27 May 1914), an English physicist, chemist, and inventor, stands as a brilliant example of the quintessential British innovator. Best known as the independent early developer of a successful incandescent light bulb, Swan's enduring legacy extends far beyond the sphere of his famous invention.
