Henry Woodward
On July 24, 1874, five years before Thomas Edison's U.S. patent, two Canadians, Henry Woodward, a medical student from Toronto, Ontario, and his friend Mathew Evans, a hotelkeeper, patented the first incandescent lamp with an electric light bulb. They produced light by running electrical current through a lumb of carbon inside an evacuated globe. They did not have enough money to develop their invention for people to use and sold a share of their patent to Thomas Edison who was also struggling with his own light bulb experiment.
