Sir Humphrey Davy.
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.
(It was obvious, though, that incandescent lighting would be a huge financial success if it could be perfected, so many inventors continued to work on finding a solution. It was into this environment that the brash, young, inventor Thomas Alva Edison entered the race to make-a-better-bulb in 1878. )

Sir Humphry Davy in the early 1800's (exact date quoted vaires between 1802 and 1809) showed that a high voltage arc between two carbon electrodes would provide illumination. The harshnes of it -- it is like an electric welding machine -- led Thomas Edison to seek a gentler alternative, which turned out to be the incandescent light bulb in 1879.

originally designed by joseph swan his design was not officially a lightbulb (they didn't work they would only light up for only half a second because they had carbonated paper filaments but i say he invented it because he was the first person to take a shot at it)
http://en.wikipedia.org/wiki/Joseph_Swan
then later (much later) thomas edison perfected swan's design by replacing the cotton filiment with tungsten and wallah light (these lasted alot longer than swan's lights)

heres some more information

and heres what swan's lightbulb looked like

Humphrey Davy, in 1800.
Thomas Edison made the system work better.
