Thomas Alva Edison
Curious about the world from an
early age, he learned all he could about the mechanical workings of object. His
laboratory at Menlo Park, New Jersey, was the forerunner of the modern research
laboratory. He expanded on the light bulb idea by creating a vacuum inside the
bulb and sending a lower of electricity into it. At the time, they had no idea
what this was and they thought he had mental problems. By the time he died,
Edison held more than one thousand patents.
