Most people think that Thomas Edison invented the light bulb, but they would be wrong. It was granted on August 3, 1874 as Canadian patent number 3,738. According to the National Research Council of Canada: Henry Woodward of Toronto, who along with Matthew Evans patented a light bulb in 1875. In 1875, Thomas Edison purchased half of a patent. The relationship of the Woodward/Evans work on the incandescent bulb to that of others, including Edison, on electric light is explained in the following passage of an article in a 1900 issue of "The first incandescent lamp [developed by Woodward and Evans] was constructed at Morrison's brass foundry in Toronto, and was a very crude affair.
Woodward was a medical student at the time. Mathew 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.. On July 24, 1874, Woodward and his partner, Matthew Evans, a hotel keeper, filed a Canadian patent application on an electric light bulb. The inventor the electric light, was Humphry Davy. Their light bulb comprised a glass tube with a large piece of carbon connected to two wires. Which one is right?© 1998 - 2016 Mysteries of Canada - All rights reservedThomas Edison did not invent the light bulb. )1880 – Edison continued to improved his light bulb until it could last for over 1200 hours using a bamboo-derived filament.You keep switching the names, James and Henry in regards to Henry Woodward. Evans was described in the patent as a “Gentleman”, but he was a hotel keeper. Edison placed his filament in a oxygenless bulb. Davy connected two wires to a battery and attached a charcoal strip between the other ends of the wires. It was not a commercial success and they eventually sold their patent to Edison in 1879. Henry Woodward was a Canadian inventor and a major pioneer in the development of the incandescent lamp.. On July 24, 1874, Woodward and his partner, Mathew Evans, a hotel keeper, filed a Canadian patent application on an electric light bulb.

Shortly after this in 1874, in Canadian, inventors Henry Woodward and Matthew Evans patented a nitrogen-filled, carbon filament lamp. Several earlier inventors working on the light bulb had progressed as far in their work as Woodward and Evans: What is known about Woodward's discovery is that it was patented in Canada and the United States prior to a patent being granted to Edison and it is known that the patent for the Canadian discovery was purchased by Edison when he was making his original investigations and before he obtained his patent.

In 1875, Edison purchased half of a patent owned by James Woodward who invented the light bulb. Woodward and a colleague by the name of Mathew Evans, filed a patent for the: Working at Morrison’s Brass Foundry on Adelaide Street in Toronto, they built the first lamp with a shaped rod of carbon. 1875 - Henry Woodward and Matthew Evans patented a light bulb. Similar to what we would do today to avoid equipment leasing issues. His lamp design worked but the cost of the precious metal platinum made this an impossible invention for wide-spread use.1835 – James Bowman Lindsay demonstrated constant electric lighting system using a prototype light bulb.1850 – Edward Shepard invented an electrical incandescent arc lamp using a charcoal filament. This technology was not used in Edison’s light bulbs until 1911. Who made the light bulb? It is then enclosed in a globe, or other vessel, either of glass or other Suitable material. The charged carbon glowed making the first arc lamp.1820 – Warren De la Rue enclosed a platinum coil in an evacuated tube and passed an electric current through it. The researcher who invented the light bulb was James Woodward.
