Master MindNapoleon Hill, on two occasions, wrote extensive memoirs about his life, starting with his youth in Wise County, Virginia, and ending, apparently, during World War II. I say "apparently" because the archives of the Napoleon Hill Foundation contain these two manuscripts, but they are obviously incomplete and end in the 1940s. Mr. Hill died in 1970. His last book, Grow Rich with Peace of Mind, was written in 1967 and sheds some light on his later years;
