Edison's Lightbulb

Thomas Alva Edison, born in Ohio on February 11, 1847, was one of the most well-known inventors of all time. He spent a few of his early years in formal schooling, but he received most of his education at home. Thomas set up a laboratory in the basement of his family's Michigan home and spent most of his time experimenting. Edison's mother, Nancy, knew her son was fond of chemistry and electronics, so she gave him books to read on the subjects. One book explained how to perform chemistry experiments at home; Thomas did every one in the book.
