  1. It was Thomas Alva Edison in 1879, wasn't it? That's what many people think and were taught in school. Like most stories, however, there is a lot more behind the creation of this important and ubiquitous object than just Mr. Edison..

    The story of the lightbulb really starts almost seventy years earlier. In 1806 Humphrey Davy, an Englishman, demonstrated a powerful electric lamp to the Royal Society. Davy's lamp produced its illumination by creating a blinding electric spark between two charcoal rods. This device, known as an "arc lamp," was impractical for most uses. The light, similar to that of a welding torch, was simply too bright to be used in residences and most businesses. The device also needed a tremendous source of power and the batteries which powered Davy's demonstration model were quickly drained.


  2. Thomas Edison of course.

  3. michael jackson!

  4. 1850  Joseph W. Swan began working on a light bulb using carbonized paper filaments

    1860 Swan obtained a UK patent covering a partial vacuum, carbon filament incandescent lamp

    1880 Thomas Alva Edison

  5. Thomas Edison

  6. THOMAS EDISON..GIMME MAH POINTZ!

  7. Thomas Alva Edison

  8. The first attempts at using electric light were made by English chemist Sir Humphry Davy. In 1802,

    The light bulb is believed by many to have been invented by Thomas Alva Edison.

    Others may be able to contribute to this answer.

    The durable incandescent bulb filament was developed by Edison. The fluorescent light on which energy efficient lighting is based was invented by a Filipino and the patent was purchased by an American company.

    Other opinions

    Hiram Stevens Maxim holds many US Patents for the "Electric Lamp". Over the years he was involved in several patent disputes with Thomas Edison. One such dispute was over the incandescent light bulb.

    The (unfortunately, largely forgotten and still extremely under-appreciated) Serbian inventor, genius, and true scientist Dr. Nikola Tesla invented the fluorescent light bulb (as well as Neon lighting and several other lighting inventions). At the time, his invention was largely ignored. In fact his fluorescent light bulbs were vastly superior than the ones we have now: they were far more energy efficient due to the lack of ballast transformers and capacitors, they needed no starter capacitor, and lasted literally forever as there was no filament necessary and nothing was consumed. Tesla is however better known for his monumental invention of AC current generators, motors and energy transmission systems - which to this day still power the entire civilized world in exactly the same way. As with almost all Tesla's inventions, his fluorescent bulb was brilliant in its simplicity, durability and efficiency, as well as easy to produce. Tesla also invented numerous improvements on the common (and extremely inefficient) incandescent light bulb for which Edison commonly is credited, although even that is disputed - Edison clearly could not stand in the shadow of the likes of Tesla and Edison is known to have shrewdly taken credit for many inventions he in fact did not produce himself.

    Canadians were on this scene as well, to the extent that Edison bought a light bulb patent from two Torontonians, James Woodward and Mathew Evans.

    In 1875, Edison purchased half of a Toronto medical electrician's patent to further his own research. That researcher was named James Woodward.

    Woodward and a colleague by the name of Mathew Evans, described in the patent as a "Gentleman" but in reality a hotel keeper, filed a patent for the Woodward and Evan's Light on July 24, 1874. Working at the Morrison's Brass Foundry on Adelaide St West in Toronto, they built the first lamp with a shaped carbon rod of carbon held between electrodes in a glass bulb filled with nitrogen.
