Perhaps the most well-known author in the field of communication and public speaking, Dale Carnegie was born into poverty on a small farm in Maryville Missouri. Devoted to public speaking from his teen years, he was active in debate in high school. Carnegie attended Warrensburg (Mo.) State Teachers College, and became a salesman for Armour and Company in Nebraska. Moving to New York City in pursuit of an acting career, he gave classes in public speaking at the Young Men’s Christian Association. Soon he was developing courses on his own, and writing pamphlets that he would eventually publish as books. Carnegie believed that the quickest way to develop self-esteem is through public speaking.
