Napoleon Hill was an American author, lecturer, journalist, and pioneer of modern personal-development literature. Born in 1883 in Wise County, Virginia, Hill rose from poverty to become one of the best-known success writers of the twentieth century. His work focused on ambition, self-discipline, confidence, persistence, leadership, cooperation, and the organized use of thought in the pursuit of personal and financial achievement.Hill's first major work, The Law of Success, was published in 1928 as a multi-volume course in achievement. It presented the ideas that would later shape his best-known book, Think and Grow Rich, and helped establish the language and structure of modern success literature. Hill claimed that his philosophy grew from years of studying successful figures in business, industry, invention, finance, and public life, and his writings frequently draw on examples of entrepreneurs, executives, and self-made men of the early twentieth century.His best-known books include The Law of Success, Think and Grow Rich, The Magic Ladder to Success, How to Sell Your Way Through Life, The Master-Key to Riches, and Success Through a Positive Mental Attitude, written with W. Clement Stone. Although some of Hill's personal claims and biographical stories have been disputed by later researchers, his influence on motivational writing, business self-help, and popular success philosophy is undeniable.Hill died in 1970, leaving behind a body of work that continues to be read by entrepreneurs, salespeople, managers, students of self-improvement, and readers interested in the history of American success literature. His emphasis on definite purpose, disciplined thinking, persistence, cooperation, and personal initiative remains central to the self-help and achievement tradition.
