Thomas Edison was an American inventor who is best known for his invention of the practical incandescent light bulb. He also invented the phonograph, the motion picture camera, and the first commercial electric power distribution system.

Looking back at his tremendous success, it's easy to forget that Elvis wasn't always the King of Rock 'n' Roll. At the same time that he was recording first hits, he was working at Crown Electric in Memphis, Tennessee, driving a supply truck and starting to train.

Benjamin Franklin (1706-1790) is one of the most well-known researchers and is considered a forefather of electricity.
