The incandescent light bulb first shone after years of work by many notable figures who contributed to the development of this revolutionary technology. Thomas Edison built on their successes and ...
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today. Learn more about the history of the incandescent light bulb.

On February 11, 2011, on what would have been Thomas Edison's 164th birthday, Google's homepage featured an animated Google Doodle commemorating his many inventions. When the cursor was hovered over the doodle, a series of mechanisms seemed to move, causing a light bulb to glow. List of people who worked for Edison
A Brief History of the Light Bulb. The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence).The filament is protected from oxidation with a glass or fused quartz bulb that is filled with inert gas or a vacuum. In a halogen lamp, filament evaporation is slowed by a chemical process that ...
Home » inventions » Who invented the light bulb? Who invented the light bulb? Who invented the light bulb? No, it wasn’t Thomas Edison. Light bulbs were in use long before Edison applied for the patent in 1879. British inventor Humphry Davy invented an incandescent light bulb in 1801 and created the “arc lamp” in 1809.
When discussion about the invention of the light bulb comes up, most people attribute it to Thomas Edison. However, contrary to popular belief, that is not true. He is not the sole inventor of the bulb, but he improved the technology, to the greatest extent. The story of this invention is a long one.
Where Was the Light Bulb Invented? The first light bulbs and its predecessors were invented in England. John Wilson Swan created the first light that can be considered a light bulb in 1850. Swan's light consisted of paper filaments in vacuum bulb. Before Swan, the earliest predecessor of the light bulb was Humphry Davy's electric light in 1802.
American inventor Thomas Edison is credited with devising the first practical light bulb in 1879. However, the story of the incandescent light bulb is not that straightforward, as it involved ...
1879 - Thomas Alva Edison invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygen-less bulb. (Edison evolved his designs for the lightbulb based on the 1875 patent he purchased from inventors, Henry Woodward, and Matthew Evans.) by 1880 his bulbs lasted 600 hours and were reliable enough to become a marketable enterprise.
