On July 24,Woodward and his partner, Mathew Evans, a hotel keeper, filed a Canadian patent application on an electric light bulb. It was granted on August 3,as Canadian patent number 3, Woodward was a medical student at the time. Their light bulb comprised a glass tube with a large piece of carbon connected to two wires. They filled the tube with inert nitrogen to get a longer burn life in the filament.

Their light bulb was fully effective and sufficiently promising; they sold their U. Patentto Thomas Edison and due to this Edison is now known for the invention of the light bulb. Thomas Edison obtained an exclusive license to the Canadian. About: Henry Woodward inventor.

Their bulb was a glass tube with a large piece of carbon connected to two wires, filled with inert nitrogen to get a longer burn life in the filament. Although the first incandescent bulb by Woodward and Evans was a crude affair, it was fully effective and sufficiently promising. However, they didn't have enough funds to develop the invention, so they sold the rights to Thomas Edison, who later obtained an exclusive license to the Canadian patent.

Woodward's invention was a crucial step towards the development of commercially practical light bulbs. Edison improved on the design, developing his own version of the incandescent lamp with a high resistance thin filament of carbon in a high vacuum contained in a tightly sealed glass bulb, which had a sufficiently long service life to be commercially practical.

The principle of the incandescent lamp dates back several decades before Woodward's experiments, and several inventors, including Marcellin Jobard, C. Although Woodward and Evans' work was a significant milestone, they were not the sole inventors of the incandescent lamp. Woodward was a medical student when he invented the light bulb, and his contribution is a testament to the power of creativity and innovation.

Although he did not achieve commercial success with his invention, it paved the way for the development of the light bulb that is now an essential part of our lives. Woodward's contribution to the development of the light bulb is a reminder that often, it is not just one inventor, but the collective efforts of several inventors over time that lead to breakthrough innovations.

He is mentioned in 'Widsith' and genealogies. Ben Urich is a fictional character in American comic books published by Marvel Comics.

Several earlier inventors working on the light bulb had progressed as far in their work as Woodward and Evans: Marcellin Jobard inC. Each contributed to the development of the incandescent lamp, but it was Edison who assembled the necessary components to make the first practical electric light bulb.

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.
