Timeline of Electricity and Light History1809 - The first "light bulb", created by Sir Humphrey Davy, consists of an electric arc passed between two poles. The light did not last long however. 1820 - A fellow named Warren De la Rue tried to create an incandescent light bulb. Using platinum coil, he passed a current of electricity through a tube. The light bulb worked, however the platinum coil proved too expensive to mass-produce. 1841 - Frederick de Moleyns using powdered charcoal filters and is granted the first patent for incandescent lamps. 1850 - Edward Shepard uses a charcoal filament to create an incandescent lamp. Joseph Swan also starts using carbon as filaments during this time. Carbon provided a lower cost and more efficient filament material than other metal alternatives at this time. 1854 - A German inventor used a filament made of carbonized bamboo to produce an incandescent electric bulb. 1860 - Joseph Swan demonstrated a decent light bulb using carbonized filaments, but failed to create a proper vacuum and enough electricity to produce a lasting light. 1879 - Thomas Edison introduces the carbonized paper filament to create a lasting light bulb. 1881 - Lewis Latimer patents a process that allows carbon filaments to be manufactured more efficiently. His process extends the life of Edison's carbon filaments, producing a longer lasting bulb. 1898 - Karl Auer tried to use osmium as a filament material for light bulbs. The substance did offer a longer life however the brightness of the bulb was compromised. 1906 - GE patents tungsten filaments for use in light bulbs. 1907 - Tungsten filaments become the standard for light bulbs, extending their efficiency and light.
