Thomas Edison was born in Milan, Ohio on February 11,1847. He was not an ordinary person. He was one of the greatest inventors in the history. (29)The phonograph, the light bulb, the movie camera, and sewing machine are just some of his many inventions that helped change the world.
    Thomas did not go to school. His mom taught him at home. When he was twelve, he got his first job at the train station as a train boy selling candy and newspapers. He loved books and he spent all his money on them. One day while trying to catch a train, a trainman reached and grabbed him by the ears. While pulling Edison up, something cracked in his ears and right after that he began to go deaf.
     When Thomas had made enough money years later, he wanted to buy a laboratory. He paid a group of scientists to think of inventions and see if the inventions would work. That setup worked so well that other companies did this too. (31)Now today every company and university in the whole world has a research department, and it all began with Edison’s research group.
    He is most famous for the invention of the electric light bulb. (30) He had burned himself with candles so many times when he read; he wanted a way to see without a candle. It took him just over a year to invent a practical light bulb. Edison founded the Electric Light Company in 1878.
    In his seventies he still worked sixteen hours a day, and was one of the most famous men in America. By the time he died at West Orange, New Jersey on October 18,1931, he had created over 1,000 inventions.
