First published in 1937, this book is the result of 20 years of research conducted by Napoleon Hill. His research started when Andrew Carnegie (the steel tycoon who was then the richest man on earth) gave him the assignment of organizing a Philosophy of Personal Achievement. Hill, who was a poor journalist, armed with just an introductory letter from Carnegie, set out to interview over five hundred successful people including Henry Ford, Thomas Edison, Alexander Graham Bell, John D. Rockefeller, George Eastman, William Wrigley Jr. and Charles M. Schwab. He then developed his secrets to success.
