Thomas Alva Edison was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. As a boy, the famous inventor Thomas Edison was not a good student. His parents took him out of school after three months and his mother taught him at home, where his great curiosity and desire to experiment often got him into trouble. One day, he set fire to his father's arm “to see what would happen”. When he was ten, he built his own chemistry laboratory. His parents became accustomed to his experiments and the explosions which sometimes shook the house.
