Nov 22, 2013 · In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.

One of the first devices to provide a reliable source of electricity was invented by the Italian inventor Alessandro Voltain 1800. The so-called “voltaic pile” ...
British physicist Joseph Swanhad studied the problems with incandescent lighting beginning with cost-effectiveness as early as 1850. At first, he used carbonized paper and cardboard as cheaper alternatives to metal filaments but found it too difficult to prevent these paper filaments from burning out quickly. He later patented a design using cotton...
Meanwhile, Thomas Alva Edison was working across the pond to solve the same problems. The 31-year old inventor had 169 patents by that time and had established a research facility in Menlo Park, New Jersey. Edison wanted to make incandescent lightbulbs both affordable and reliable, too. He studied his competition in this endeavor which naturally in...
Then in October 1879, Edison settled on a thinner, higher-resistance cotton filament than the one Swan had used. He reasoned that the higher the resistance in the filament, the less electrical current would be required to make it glow. His 1879 design burnedfor 14.5 hours. For his realization regarding high resistance, Edison is generally credited ...
The same month that Edison developed his lightbulb, Joseph Swan announced he had perfected his own and obtained a British patent for it on Nov. 27, 1880. Swan’s home was the first in history to be lit with electric light and he also was responsible for lighting the Savoy Theater 1881. This was the first time a large public building was lit entirely...

Mar 13, 2018 · Edison was able to produce over 13 continuous hours of light with the cotton thread filament, and filed his first light bulb patent on January 27, 1880. Later, he and his researchers found that the ideal filament substance was carbonized bamboo, which produced over 1,200 hours of continuous light.
