Nov 22, 2013 · In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.

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...

Jul 2, 2019 · Sir Joseph Swann of England and Thomas Edison both invented the first electric incandescent lamps during the 1870s. Incandescent light bulbs work in this way: electricity flows through the filament that is inside the bulb; the filament has resistance to the electricity; the resistance makes the filament heat to a high temperature; the heated ...
Joseph Swan was its inventor. Born in Sunderland, he studied chemistry and moved to Tyneside where, after many years of persistent effort, he created the first successful 'incandescent filament...
