I don't think so. I think someone else invented the lightbulb

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. In 1835, the first constant electric light was demonstrated, and for the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament (the part of the bulb that produces light when heated by an electrical current) and the bulb’s atmosphere (whether air is vacuumed out of the bulb or it is filled with an inert gas to prevent the filament from oxidizing and burning out). These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy.

When Edison and his researchers at Menlo Park came onto the lighting scene, they focused on improving the filament -- first testing carbon, then platinum, before finally returning to a carbon filament. By October 1879, Edison’s team had produced a light bulb with a carbonized filament of uncoated cotton thread that could last for 14.5 hours. They continued to experiment with the filament until settling on one made from bamboo that gave Edison’s lamps a lifetime of up to 1,200 hours

-- this filament became the standard for the Edison bulb for the next 10 years. Edison also made other improvements to the light bulb, including creating a better vacuum pump to fully remove the air from the bulb and developing the Edison screw (what is now the standard socket fittings for light bulbs).

One can’t talk about the history of the light bulb without mentioning William Sawyer and Albon Man, who received a U. S. patent for the incandescent lamp, and Joseph Swan, who patented his light bulb in England. There was debate on whether Edison’s light bulb patents infringed on these other inventors’ patents. Eventually Edison’s U. S. lighting company merged with the Thomson-Houston Electric Company -- the company making incandescent bulbs under the Sawyer-Man patent -- to form General Electric, and Edison’s English lighting company merged with Joseph Swan’s company to form Ediswan in England.

No. Einstein had nothing to do with light bulbs.

Thomas Edison is often credited with inventing the light bulb, but that's not the whole truth.

Electric lights already existed in the form of arc lights - electrical current arcing across two electrodes that gave off visible light - but these were extremely bright, and used a lot of current, and weren't practical for providing illumination in a normal room. What was needed was a bulb that gave off a nice glow of light that wasn't super bright like the arc light.

A number of more conventional "high resistance" light bulb designs existed before Edison went to work on them, but they simply didn't last very long before their filaments would burn up - the best only lasted a couple of minutes. Edison's contribution was that he tried over 6,000 different filament materials before finding one that had both high resistance and a reasonably long life: a cotton thread covered in powdered carbon. With refinements, these bulbs could last many hours, compared to the seconds or minutes of previous bulbs. The Edison bulb was the first light bulb that was a realistic consumer product - the others were really just lab experiments.

Later, tungsten filaments would be used that greatly increased filament life to thousands of hours, but those early Edison bulbs could last 20-50 hours, and that was practical enough to sell at the time.

Sigh, did you learn nothing at school?

I know they try and pitch things that Jews invented everything, but we invented very little. Most inventions were creative ventures between multiple people. But it's usually the first to patent who gets the glory.

But the incandescent lightbulb was patented by Edison

ChrisMaster69 · Answer

There were various inventors looking at it, however the first inventor of any note was Joseph Swan  both him and Edison eventually worked together and formed their own company.

The first practical incandescent bulb was invented by Edison.

Before that there were arc flash lights (it's why we use the term "flashlight" ) but no bulbs that would last more than a very short length of time.

Edison's idea to put inert gas (CO2) in the bulb made them possible. He also had to invent the light socket, the fuse, the switches, outlets, etc and he had wire up the first homes and supply them with electricity and market it to make it widespread.

Thomas Edison invented the light bulb.
Albert Einstein came up with the theories of special relativity, general relativity, the explanation for brownian motion, and the equivalence of mass and energy (E=mc^2).

AviatorTom · Answer

American Thomas Alva Edison is credited with inventing the incandescent light bulb, although several others (including British Humphrey Davy) invented a form of electric light years before him.
