Napoleon Hill
Oliver Napoleon Hill (October 26, 1883 – November 8, 1970) was an American self-help author. He is best known for his book ''Think and Grow Rich'' (1937), which is among the best-selling self-help books of all time. Hill's works insisted that fervid expectations are essential to improving one's life. Most of his books are promoted as expounding principles to achieve "success".Hill is a controversial figure. Accused of fraud, historians also doubt many of his claims, such as that he met Andrew Carnegie and that he was an attorney. Provided by Wikipedia
