Napoleon Hill’s 1937 self-help classic Think and Grow Rich remained entrepreneurship bible through 2010s-2020s, selling 100+ million copies with success-through-mindset philosophy.

Book Origins

Published 1937 during Great Depression, Hill claimed to have studied 500+ successful people (Andrew Carnegie, Henry Ford, Thomas Edison) over 20 years to distill success principles.

Historical note: Much of Hill’s backstory (Carnegie commission, Edison meetings) lacks documentation; biographers debate accuracy.
