    Light Bulb Timeline

    SourceSource The light bulb is one of the everyday conveniences that affects our lives. Thomas Edison is credited for the invention mainly because his version was more efficient.
  • Davy Invents First Lightbulb

    Davy Invents First Lightbulb
    SourceSir Humphry Davy, English chemist, was born on the 17th of December 1778 at or near Penzance in Cornwall. Humphry Davy created a crude version of a light bulb by connecting two wires to a battery with a charcoal strip between the ends of the wires.
  • Warren de La Rue

    Warren de La Rue
    SourceBorn January 15, 1815, Guernsey, Channel Islands, Warren de la Rue created a more efficient light bulb in 1820 by using 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 uses Prototype

    James Bowman uses Prototype
    SourceJames Bowman Lindsay used a prototype lightbulb to demonstrate a constant electric lighting system. This prototype had no smell, emitted no smoke, was incapable of explosion, and did not require air for combustion could be kept in sealed glass jars.
  • Heinrich Creates First Real Light Bulb

    Heinrich Creates First Real Light Bulb
    Heinrich Göbel, the son of a gardener, was born on April,20th 1818 in Springe, which lies at the foot of the Deister. He made the first true lightbulb using a carbonized bamboo filament inside a bulb of glass. His invention caused many to stop and look at it, but its further sucess was not a revolutionary invention
  • Sir Joseph Wilson Swan

    Sir Joseph Wilson Swan
    Born in England on October 31st, 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.
  • Edison Founds Electric Company

    Edison Founds Electric Company
    SourceThomas Edison founded the Edison Electric Light Company to finance his efforts to invent a practical incandescent electric lamp. This and various other electric companies established by Edison will later be combined in what becomes the General Electric Company.
  • Edison Improves on Lightbulb

    Edison Improves on Lightbulb
    Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. None of the earlier inventions were efficient, safe, or cheap. Thomas Alva Edison invented a carbon filament that was able to burn for forty hours. He placed this filament in a bulb without oxygen.
  • Edison Shows Public Demonstration

    Edison Shows Public Demonstration
    SourceBefore Edison could make his millions, he had to perfect all of the elements in the light bulb like durability, safety, and other elements. The first public demonstration of the Thomas Edison's incandescent lighting system was in December 1879, when the Menlo Park laboratory complex was electrically lighted. Edison spent the next several years creating the electric industry.
  • Whitnew Changes Light Bulb

    Whitnew Changes Light Bulb
    Willis Whitnew created a metal-coated carbon filament that would not darken the interior of the bulb. This was the predecessor of the tungsten filament.
  • Coolige Improves Filament

    Coolige Improves Filament
    William David Coolidge improved the method of manufacturing tungsten filaments. This filament lasted longer than all other types and made it practical to manufacture and use.
