Dale Carnegie, born on 24 November, 1888, was a farmer’s son from Maryville, Missouri. He developed public-speaking skills and graduated from the State Teacher’s College in 1908. Starting his career selling correspondence courses, he became a successful salesman for Armour & Company. In 1911, he pursued his dream of becoming a Chautauqua lecturer and later found his calling as a public-speaking instructor. His innovative teaching methods, including encouraging students to speak about their anger, led to the evolution of the Dale Carnegie Course. Carnegie’s influential book, How to Win Friends and Influence People, became a bestseller, selling five million copies worldwide. He critiqued over 150,000 speeches and trained 450,000 graduates through the Dale Carnegie Institute. Carnegie’s achievements in public speaking and personal development left a lasting legacy.
