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.
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.
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 real history of who created the first lightbulb goes back decades before Thomas Edison patented the carbon filament bulb in October 1879. Meet the largely-forgotten pioneers who started creating the light bulb some 80 years before Thomas Edison "invented" it.
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. The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glows.
With its evolution in the 19th century and its terminal decline in the 21st, the incandescent light bulb dominated both domestic and public lighting for the entire 20th century. It was a technology that changed the way we lived, worked and were...
The mercury pump, invented in 1865, provided an adequate vacuum, and a satisfactory carbon-filament bulb was developed independently by the English physicist Sir Joseph Wilson Swan in 1878 and by the American inventor Thomas Alva Edison the following year.
Long before Thomas Edison patented -- first in 1879 and then a year later in 1880 -- and began commercializing his incandescent light bulb, British inventors were demonstrating that electric light was possible with the arc lamp.
Using lower current, a small carbonized filament, and an improved vacuum inside the globe, Edison successfully demonstrated the light bulb in 1879 and, as they say, the rest is history. Suffice it to say, light bulbs developed over a period of time.
With its evolution in the 19th century and its terminal decline in the 21st, the incandescent, light bulb dominated both domestic and public lighting for the entire 20th century. It was a technology that changed the way we lived, worked and were entertained.
