Edison. He was one of the greatest scientists in the twentieth

century. He was famous around the world as an inventor as well. In 1879, he succeeded in inventing

had over one thousand inventions and made a great contribution to the development of mankind. I

consider him as my hero. From him, I have learned that whatever difficulties I meet, I should never

give up.
