Thomas Edison was one of the greatest

inventors in history. In 1877, at his

lab in Menlo Park, New Jersey, he built

the phonograph, a machine that could

record sound. The first words he

recorded were "Mary had a little lamb."

In 1879, he and his team made an

electric light bulb that could glow for

hours. In the end, he had 1,093 U.S.

patents. People called him "the Wizard

of Menlo Park."
