Who Really Invented The Light Bulb? Was that really Edison?
The Electric Bulb, one of the best everyday conveniences was not "invented" in the traditional sense in 1879 by Thomas Edison, before him over 20 inventors created their own Electric Bulb Designs! So why Edison is often crowned with this amazing human achievement? Let's find out!
In 1802 Humphry Davy experimented with electricity and invented an electric battery, then he connected his battery to a piece of carbon and for the very first time light was produced using electricity. But their was a drawback to it, it was too much bright and didn't last long enough.
Then in 1840, British scientist Warren de la Rue created a new design which could last longer and was efficient because the design incorporated a Coiled Platinum Filament. Although it lasted longer, Platinum was not cheap and it was not affordable for household and commercial use.
Again in 1850, an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb. And by 1860 he had a working prototype, but the lack of a good vacuum and an adequate supply of electricity resulted in a bulb whose lifetime was much too short to be considered an effective producer of light.
Here comes the interesting part, on July 24, 1874, a Toronto medical electrician named Henry Woodward and a colleague Mathew Evans filed a patent of their electric lamp, but they were not able to commercialize their lamp and were unsuccessful.
Now comes Edison, Edison purchased the patent from Henry and Mathew in 1878 and began some serious research into developing a practical incandescent lamp. After filing many patents, on november 4, 1879 he finally filed a patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires.", but it was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1200 hours.
This discovery marked the beginning of commercially manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company began marketing its new product.
