  4. Port Huron, Michigan • Moved to Port Huron by railroad train when seven • Removed from formal schooling at age 12 • Realized worth of education • Sponsored Edison scholarships

  5. First Laboratory • At age 11 had a chemical laboratory • Read many books • Gibbon’s “Decline and Fall of the Roman Empire” • The “Dictionary of Sciences” • At age 12 had a job as newsboy and candy “butcher” • “The Weekly Herald”

  6. Edison’s Deafness • Tale • Caused by trainman who boxed his ears when Edison’s traveling laboratory caught fire • Truth (Edison’s Truth) • Caused by trainman who picked him up by the ears to get him on a train pulling out of the station

  7. Edison’s Beginnings How Edison got introduced into the world of electricity

  8. Train Rescue & Reward • Before age 17 Edison risked his life to save a station agent’s young boy • In return, Edison was taught telegraphy • First insight to electricity and the beginning of his studies and experiments

  9. Telegrapher Jobs • At age 17 became a regular telegrapher on the Grand Trunk Line in Ontario • Creative invention got him fired • Device to automatically “report in” in Morse code every hour • Found a job with Western Union in Boston • Ended up in New York poor and in debt

  11. Incandescent Lamp The creation of a commercially viable incandescent electric lamp

  12. Light History • Gas lights were prevalent before 1879 • Many inventors worked to create incandescent light stemming from electric arc lamp • James Prescott Joule • Sir Humphrey Davy

  13. Edison’s Success • Contributing factors • Durable incandescent material • A better vacuum within the bulb • Filament material of high resistance • Platinum • Carbonized Japanese bamboo • Tungsten

  14. Critical System Elements • Parallel circuit • Durable light bulb • Improved dynamo • Underground conductor network • Devices for maintaining constant voltage • Safety fuses and insulating materials • Light sockets with on-off switches

  15. Following Inventions Inventions following the success of the incandescent electric lamp

  16. The “Edison Effect” • First application in the field of electronics • Phenomenon where an independent wire or plate, when placed between the legs of the filament in an electric bulb, serves as a valve to control the flow of current

  17. Other Inventions • Motion picture camera • Invented and patented in 1888 • Steel alkaline storage battery • Improved Edison battery in 1910 • Boost to electric car manufacturers • Short-lived • Rubber • U.S. dependent on foreign sources during WWI • Made from goldenrod

  18. Electric Companies Following Edison’s success multiple electric companies were formed

  19. General Electric • Edison General Electric was formed in 1889 from various smaller companies • Edison never controlled company • General Electric was formed after Edison General Electric and leading competitor Thompson-Houston merged

  21. Conclusion Thomas Alva Edison’s impact

  22. Conclusion • Affected life as we know it today • Huge discoveries and improvements • Incandescent light bulb • Phonograph • Motion camera • Still remembered today through the existence of General Electric
