In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.
The story of the lightbulb begins long before Edison patented the first commercially successful bulb in 1879. In 1800, Italian inventor Alessandro Volta developed the first practical method of...
Thomas Edison was a prolific inventor and savvy businessman who acquired a record number of 1,093 patents (singly or jointly) and was the driving force behind such innovations as the...
Did Thomas Edison invent the first light bulb? Here you’ll find a brief history of the light bulb as well as a timeline of notable dates in lighting history.
Edison Light Bulb, 1879. Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention—the light bulb, the first practical electric incandescent lamp.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation.
The modern light bulb, which hasn't changed drastically since Edison's model, is made up of only a handful of parts. In this article, we'll see how these parts come together to produce bright light for hours on end.
Joseph Swan, alongside Thomas Edison, is the person most credited with the invention of the light bulb. The Sunderland-born chemist created the first successful incandescent filament electric lamp and gave public demonstrations of it in late 1878 and early 1879.
Though he didn’t come up with the whole concept, his light bulb was the first that proved practical, and affordable, for home illumination.
lightbulb, electric incandescent lamp based on a glowing metallic filament enclosed within a glass shell filled with an inert gas such as nitrogen. See incandescent lamp; lamp. This article was most recently revised and updated by Amy Tikkanen.
