Dale Carnegie was a groundbreaking American author and motivational speaker who revolutionized the field of personal development and communication. Born into a poor farming family, Carnegie rose from humble beginnings to become one of the most influential figures in the self-help industry.
After graduating from State Teacher’s College in Warrensburg, Missouri, he worked as a salesman and actor before developing a course in public speaking and self-confidence for adults. His classes became so popular that they laid the foundation for the Dale Carnegie Training organization, which now operates in more than 90 countries and has trained millions of people.
