Thomas Edison was born in 1847, and died in 1931. When he was a child, he was always trying out new ideas. When he was five years old, one day his father saw him sitting on some eggs. He asked his father,"Hens are able to have chicks. Why can't I?"
  Young Tom was in school for only three months. His teacher didn't think he was a good pupil, because he asked a lot of strange questions. So the teacher sent him away from school. And his mother began to teach him herself. He became interested in science. He grew vegetables and sold them. With the money he built a science lab.
  Years later, he became a great inventor!
