Who invented light

Thomas Edison was the inventor who finally cracked the code of a truly practical light bulb, but this only came after years of experimentation. Working in a company he called the Edison Electric Light Company, Edison developed a high-resistance cotton filament, which burned for over 14 hours in a test.

It also consumed far less electricity than competing designs.

Additionally, Edison benefited from the Sprengel air pump, invented in 1877, which greatly improved vacuum pump technology and allowed manufacturers to suck outside gasses out of a glass bulb.

This, combined with the high electrical resistance of cotton, allowed filaments to burn far longer.

Who invented the lightbulb before edison

Edison filed for his first patent in 1879, and the U.S. Patent Office granted it in January 1880. Edison would go on to found the Edison Illuminating Company.

Note that Edison Illuminating Company was never part of General Electric, another company Edison founded.

Rather, Edison Illuminating Company created the first electrical generating stations in America, which operated under t
