Invention Of The Light Bulb

Invention Of The Light Bulb


Do you know who invented the light bulb? Sure, most will say, Edison was, But that's not true.. Although Thomas Alva Edison in 1879 developed a carbon-filament lamp and started with this light bulb industrial mass production. The press then announced the invention as a sensation - but because it was actually a quarter of a century old. A native of Germany, watchmaker Heinrich Goebel had in fact in 1854 brought the first usable light bulb with a carbonized bamboo fiber glow. A court later stated that he was the real inventor. Only he did not let his idea patented.

Heinrich Goebel, born 1818 in Springfield am Deister, he was a very bad student. However, he attested to his teacher in the final certificate in 1832 an "inventive mind". Goebel learned watchmaker, opened a shop for mechanics and optics and always spent a lot of time in his workshop to tinker with arc and incandescent lamps. In 1848 he immigrated with his wife and two children to America and had in New York again watch making and optics business.

 He continued his experiments continue with the bulbs and finally found the right material for the filament. Supposedly his cane to have brought the idea to put a charred bamboo fiber in a 4711 bottle of Eau de Parfum him. With a mercury venting he created a vacuum inside the glass bulb and prevented the burning out of the thread. Goebel further tinkering on his invention and should have been reached in 1859 with its lamps burn time of 400 hours. He lit so that his shop window. But that was said to be so bright that the neighbors complained and Goebel had to reduce the lighting again.

1879 Edison then tinkered on the principle of light bulb and set out on the intensive search for a suitable filament. 2000 materials he allegedly tested until he tried it with a charred cotton thread. Its bulb burning for 40 hours. Meantime Werner Siemens invented the dynamo, so that these bulky batteries were no longer necessary to generate electricity, which had to be charged by huge exciters again in Germany. The bulb could be put on the market.
