Who invented the incandescent light bulb?

A relatively easy question one would imagine.

Think and do a little research before responding.

Well, not sure what you are defining as an incadescent light bulb, so here is the history of the topic from inventors.about.com

1809 - Humphry Davy, an English chemist, invented the first electric light. Davy connected two wires to a battery and attached a charcoal strip betwween the other ends of the wires. The charged carbon glowed making the first arc lamp.
1820 - Warren De la Rue enclosed a platinum coil in an evacuated tube and passed an electric current through it. His lamp design was worked but the cost of the precious metal platinum made this an impossible invention for wide-spread use.
1835 - James Bowman Lindsaydemonstrated constant electric lighting system using a prototype lightbulb.
1850 - Edward Shepard invented an electrical incandescent arc lamp using a charcoal filament. Joseph Wilson Swan started working with carbonized paper filaments the same year.
1854 - Henricg Globel, a German watchmaker, invented the first true lightbulb. He used a carbonized bamboo filament placed inside a glass bulb.
1875 - Herman Sprengel invented the mercury vacuum pump making it possible to develop a practical electric light bulb. Making a really good vacuum inside the bulb possible.
1875 - Henry Woodward and Matthew Evans patented a lightbulb.
1878 - Sir Joseph Wilson Swan (1828-1914), an English physicist, was the first person to invent a practical and longer-lasting electic lightbulb (13.5 hours). Swan used a carbon fiber filament derived from cotton.
1879 - Thomas Alva Edison invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb. (Edison evolved his designs for the lightbulb based on the 1875 patent he purchased from inventors, Henry Woodward and Matthew Evans.)
1880 - Edison continued to improved his lightbulb until it could last for over 1200 hours using a bamboo-derived filament.
1903 - Willis Whitnew invented a filament that would not make the inside of a lightbulb turn dark. It was a metal-coated carbon filament (a predecessor to the tungsten filament).
1906 - The General Electric Company were the first to patent a method of making tungsten filaments for use in incandesent lightbulbs. The filaments were costly.
1910 - William David Coolidge (1873-1975) invented an improved method of makingtungsten filaments. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical.
1925 - The first frosted lightbulbs were produced.
1991 - Philips invented a lightbulb that lasts 60,000 hours. The bulb uses magnetic induction.

Who is IT missing? (I didn't come up with the list)

Volta? The science experiment in 1800 was not used to demonstrate light, but heat, so I don't think that would be included.

My suspicion, not certain knowledge, based on the initial presentation is that some people were conspiracied/fed to the fishes and stu wants to see if we know about them. Especially since Edison may well have been indirectly involved in one dissappearance re: motion picture camera.

Well if that is the case we wouldn't know the answer then, if the conspirators were any good at their jobs.

Sir Joseph Wilson Swan (31 October 1828 – 27 May 1914) was a British physicist and chemist, most famous for the invention of the incandescent light bulb for which he received the first patent in 1878. His house was the first in the world to be lit by a lightbulb.

Edison collaboration

In America, Edison had been working on copies of the original Swan patent, trying to make them more efficient. Though Swan had beaten him to this goal, Edison obtained patents in America for a fairly direct copy of the Swan light, and started an advertising campaign which claimed that he was the real inventor.[citation needed] Swan, who was less interested in making money from the invention, agreed that Edison could sell the lights in America while he retained the rights in Britain.[citation needed]

While searching for a better filament for his light bulb, Swan inadvertently made another advance. In 1881, Swan developed and patented a process for squeezing nitro-cellulose through holes to form conducting fibres. His newly established Swan Electric Company, which by merger was to become the Edison and Swan United Company, used the cellulose filaments, that Swan had invented, in their bulbs.[4]
Ediswan

In 1883 the Edison & Swan United Electric Light Company was established. Known commonly as "Ediswan" the company sold lamps made with a cellulose filament that Swan had invented in 1881. Variations of the cellulose filament became an industry standard, except with the Edison Company. Edison continued using bamboo filaments until the 1892 merger that created General Electric, and that company then shifted to cellulose.

I think Caryp's answer is better. You didn't ask who had the first patent or who first lit his house with an incandescent lightbulb. Some of the stuff on the list he cited pre-dates Swan.

It sounds to me like the best answer is Humphry Davy.

ETA: Or maybe Globel.

The lightbulb has become an iconic symbol for an "A ha!" moment.

I wonder what they used before its invention?
