Light Bulb Invention Milestones:

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 Lindsay demonstrated 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.
