On This Day - October 21st 1879
Thomas Edison successfully demonstrates the first commercially viable electric light bulb.
Thomas Alva Edison was born on 11 February 1847, in Milan, Ohio, USA. Although probably best known for developing the light bulb, Edison was a prolific inventor, registering 1093 patents by the time he died in 1931. On 21 October 1879, Edison demonstrated the first durable and commercially practical incandescent lamp. The bulb lasted 40 hours before burning out.
Edison was not the first to experiment with the idea of electric lighting. Many before him had developed the incandescent bulb, but none was practical enough for everyday use in the home. Edison tested over 6,000 types of vegetable matter, including baywood, boxwood, hickory, cedar, flax and bamboo as material to use for the filament. He achieved success when he experimented with a filament of carbonised sewing thread.
