Sir Humphry Davy
He passed an electric current through a strip of platinum and made it glow. -
Sir Humphry Davy
He invented an arc lamp using carbon rods but the light was way to bright. -
Warren de la Rue
He used a platinum coil enclosed in an evacuated tube to carry an electric current. The lamp worked well but the cost of platinum made this impractical. -
James Bowman Lindsay
He developed a prototype lightbulb to demonstrate a constant electric lighting system. -
Warren de la Rue
British scientist, enclosed platinum in a vacuum tube creating a functional lasting light bulb but the high price of platinum made it hard. -
Frederick de Moleyns
He was granted the world's first patent for an incandescent lamp, using powdered charcoal heated between two platinum wires contained within a vacuum bulb. -
Edward Shepard
He created an electrical incandescent arc lamp that uses a filament made of charcoal. -
Robert Houdin
He demonstrated the first perfected incandescent light bulb. -
Heinrich Göbel
A German inventor, developed the first modern lightbulb. -
Henry Woodward and Matthew Evans
They patented their version of the lightbulb. -
Sir Joseph Wilson Swan
A physicist from England, invented a practical light bulb that lasted 13.5 hours using a carbon fiber filament made of cotton. He got a UK patent for his improved incandescent lamp inside a vacuum tube. -
Thomas Alva Edison
He invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb. -
Thomas Alva Edison
He continued to improved his lightbulb until it could last for over 1200 hours using a bamboo-derived filament. -
Willis Whitnew
He invented a filament that would not make the inside of a lightbulb turn dark. It was a metal-coated carbon filament -
The General Electric Company
They were the first to patent a method of making tungsten filaments for use in incandesent lightbulbs. The filaments were costly. -
William David Coolidge
He invented an improved method of making tungsten filaments. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical. -
Frosted Lightbulbs
The first frosted lightbulbs were produced. -
Philips
He invented a lightbulb that lasts 60,000 hours. The bulb uses magnetic induction.
