  • 1. Edison BY: DENA GHAZI
  • 2.  
  • 3. <ul><li>Thomas Alva Edison is one of the most highly regarded American inventors whose creations helped to enhance the lives of people . He was born in Milan, Ohio . As a child, Thomas Edison was a dreamer . Experimenting and reading were his favorite pastimes . </li></ul>Introduction
  • 4. <ul><li>You only have to look around you to see things that Thomas Alva Edison invented or made better . The prolific inventor ( in his 84 years, Edison had 1,093 patents to his name ) contributed to the incandescent light bulb, phonograph, electrical systems, motion picture camera, telegraph, telephone, X - ray </li></ul>A glance of his inventions
  • 5. . Teacher Thought Edison was Addled <ul><li>Edison was an inquisitive child but a poor student as his mind often wandered . The youngest of 7 siblings, &quot; Al &quot; as he was called in his youth, was deemed &quot; addled &quot; by his school teacher . </li></ul><ul><li>When she found out, Edison’s mother was angry and pulled him out of school after only three months of formal education . She home schooled him instead . Edison later recounted &quot; My mother was the making of me . She was so true, so sure of me, and I felt I had some one to live for, some one I must not disappoint . &quot; </li></ul>

  • 7. Edison Built His First Lab at the Age of 10 <ul><li>When Edison turned 9, his mother gave him an elementary science book on how to do chemistry experiments at home . Edison was hooked : he did every experiments in the book and soon spent all his spare money buying chemicals . </li></ul><ul><li>At the tender age of 10, Edison built his first science laboratory in the basement of his family’s home . His father tried to bribe him with a penny if only Edison would get out of the basement and go read a book . This he did, but he also used the penny to buy more chemicals for experiments . And to make sure no one took his prized chemicals, he labeled all his bottles “poison” </li></ul>
  • 8. Edison Was Deaf and He Liked It That Way! <ul><li>At around the age of 12, Edison started to lose his hearing . One legend has it that a train conductor smacked him in the ears after he started a fire in a boxcar by doing experiments . Edison himself said that he was injured when the conductor picked him up by the ears onto a moving train . Others had said that it caused by a bout of scarlet fever during childhood . In all likelihood it was a genetic condition as both Edison’s father and one of his brothers also suffered from hearing loss . </li></ul><ul><li>But one thing’s for sure : Edison actually liked being deaf </li></ul>
  • 9. <ul><li>(technically, he was hard of hearing , not completely deaf ). </li></ul><ul><li>He said that it made it easier for him to concentrate on his experiments . </li></ul><ul><li>Oh, one more thing : Edison actually did have a laboratory in a boxcar that caught on fire ! Then 12-year - old Edison took a job selling newspaper and candies on the Grand Trunk Railroad from Port Huron to Detroit . He set up a lab for chemistry experiments and a printing press in the baggage car, where he published the Grand Trunk Herald , the first newspaper published on a train . </li></ul>
  • 10.  
  • 11. Edison Saved a Boy From a Runaway Train <ul><li>At the Grand Trunk Railroad, 14-year - old Edison saved 3-year - old Jimmie Mackenzie from a runaway boxcar . Jimmie’s father, station agent J . U . Mackenzie was so grateful that he taught Edison how to operate the telegraph machine . </li></ul><ul><li>Later, Edison became a telegraph operator for Western Union . He requested the night shift so he could have more time for his experiments . One day he accidentally spilled sulphuric acid while experimenting on a battery . The acid ran between the floorboards and onto his boss’ desk below . Needless to say, Edison was fired the next morning </li></ul>
  • 12.  
  • 13. Edison’s First Patented Invention was a Flop <ul><li>In 1869, when Edison was just 22 years old, he got his first patent for a telegraphic vote - recording machine for the legislature . Each legislator would move a switch on Edison’s machine that would record his vote on a particular bill . </li></ul><ul><li>When a business partner brought the invention to Washington D . C . , this is what Congress had to say about it : </li></ul>
  • 14. <ul><li>The chairman of the committee, unimpressed with the speed with which the instrument could record votes, told him that &quot; if there is any invention on earth that we don’t want down here, that is it .&quot; The slow pace of roll call voting in Congress and other legislatures enabled members to filibuster legislation or convince others to change their votes . Edison’s vote recorder was never used . From then on, Edison decided that he would only invent something if there was a market for it . </li></ul>
  • 15. Edison Has a Mysterious Tattoo on His Arm <ul><li>According to a 1911 policy with the Mutual Life Insurance Company of New York, Edison had five dots tattooed on his left forearm . No one knew what the dots meant . </li></ul><ul><li>Interestingly, Edison was credited for inventing the basic tattoo machine . In 1876, he patented the Stencil - Pens , an engraving device that many years later was modified by Samuel O’Reilly to make the world’s first tattoo machine . </li></ul><ul><li>Though it would’ve been a neat thing, there was simply no evidence that Edison used his invention to give himself a tattoo . </li></ul>
  • 16.  
  • 17. His death <ul><li>He passed away at age 84 on October 18th, 1931 - on the anniversary date of his invention of the incandescent bulb . </li></ul>
