Perhaps as important, people had grown accustomed to the idea of lighting with gas.

He tested thousands and thousands of other materials to use for the filament. Wilbur and Orville read everything about flight that they could get their hands on in Dayton. In 1878, Swan developed a longer lasting light bulb using a treated cotton thread that also removed the problem of early bulb blackening. American Milestones: In 1880, Swan gave the world's first large-scale public exhibition of electric lamps at Newcastle upon Tyne England. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing electric arc lamps, which were too bright to be used for small spaces such as the rooms of a house.

How Edison Invented the Light Bulb — And Lots of Myths About Himself

Thread a wire through each hole in the lid. Here at Bulbs.

This page revised January 30, 2007. The bulb is the glass enclosure which keeps the filament in a vacuum or low-pressure noble gas, or a halogen gas in the case of quartz-halogen lamps in order to prevent oxidation of the filament at high temperatures. When the Ford Motor Co.

Inventions: Light Bulb & Telephone

Share Science Lesson: This was the American Electric Company which existed until 1883 when it was reorganized and was renamed the Thomson-Houston Electric Company. When the Edison General Electric Company merged with Thomson-Houston in 1892, a bitter struggle developed, Edison's name was dropped, and Edison himself had no more involvement with the newly formed General Eclectic Company beyond defending his patents.

That first flight last only 12 seconds and covered 120 feet, but it was still the first-ever controlled, heavier-than-air flight. The company made some of the earliest installations of this new technology using Maxim's patent on a carbon-filament lamp, which was similar to that invented by Edison in 1879. So how does this amazing invention work? When he was 12, Edison got a job selling newspapers on a train that made day trips between his hometown of Port Huron, Michigan and Detroit.

They decided to stop flying until they could get a sales contract. The danger of running electrical current through the filament is that the resulting high temperatures may cause the filament to combust , or catch on fire. He did it his way. His genius gave us electric lights in our home.

Edison Papers Rutgers University has a section of their site dedicated to Edison.

The process hinges on the ability to have a variable electrical current. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Thomson-Houston Electric Company In the late 1870's high school teachers Elihu Thomson, a teacher of physics and chemistry, and Edwin Houston, a science teacher, began experimenting with and patenting improvements on existing arc lamp and dynamo designs.
