Matthew Evans is one of two Canadians who developed and patented an incandescent light bulb, on July 24, 1874, five years before Thomas Alva Edison's U.S. patent on the device. Evans, from Toronto, Ontario, and his friend Henry Woodward, made the light bulb by sending electricity through a filament made of carbon. Evans was a hotelier.
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.
Worked as a draftsman for both Alexander Graham Bell and Thomas Edison; invented the more durable filament, which made the incandescent light bulb last long enough to be useful; became a member of Edison's Pioneers and served as an expert witness in many light bulb litigation lawsuits; said to have invented the water closet.

The modest success of the Moore tubes was among the drivers for developing better filaments for standard incandescent light bulbs. Tungsten filament bulbs were a sufficient enough improvement over carbon filaments that the Moore tubes "gradually disappeared from the market, leaving only short carbon-dioxide tubes in use for color matching, in ...
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]

The pendant light at Fire Station #6 in which the bulb is installed. The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket ...
