- 4. THOMAS ALVA EDISON ( 1847– 1931 ) Inventor Thomas Edison created such great innovations as the electric light bulb and the phonograph. A savvy businessman, he held more than a 1,000 patents for his inventions.
- 5. MAIN LIFE Born on February 11, 1847, in Milan, Ohio, Thomas Edison rose from humble beginnings to work as an inventor of major technology. Setting up a lab in Menlo Park, some of the products he developed included the telegraph, phonograph, electric light bulb, alkaline storage batteries and Kinetograph (a camera for motion pictures). He died on October 18, 1931, in West Orange, New Jersey.
- 6. YOUNGER LIFE Inventor Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He was the last of the seven children of Samuel and Nancy Edison. Thomas's father was an exiled political activist from Canada. His mother, an accomplished school teacher, was a major influence in Thomas’ early life. An early bout with scarlet fever as well as ear infections left him with hearing difficulties in both ears, a malady that would eventually leave him nearly deaf as an adult. Edison would later recount as an adult, with variations on the story, that he lost his hearing due to a train incident where his ears were injured. But others have tended to discount this as the sole cause of his hearing loss.
- 7. In 1854, the family moved to Port Huron, Michigan, where Edison attended public school for a total of 12 weeks. A hyperactive child, prone to distraction, he was deemed "difficult" by his teacher. His mother quickly pulled him from school and taught him at home. At age 11, he showed a voracious appetite for knowledge, reading books on a wide range of subjects. In this wide-open curriculum Edison developed a process for self-education and learning independently that would serve him throughout his life.
- 9. MERITS AND DEMERITS OF EDISON’S INVENTIONS MERITS • Phonograph : People can listen to music • Light bulbs : Could be replaced with fire lamps which often burned DEMERITS • Phonograph : People listen to too much of music • Light bulbs : Uses electricity and people don’t switch it off
- 10. CONCLUSION Many of the inventions Thomas Alva Edison invented are being developed into more efficiently working machines and his inventions are being forgotten by the world who used to respect him for his inventions.
