    Dale Carnegie(戴尔·卡耐基) was an American writer and lecturer, and the developer of famous courses in self-improvement, salesmanship, corporate training, public speaking and interpersonal skills.

Born in 1888 in Maryville, Missouri, Carnegie was a poor farmer's boy. His family moved to Belton, Missouri when he was a small child. In his teens, though still having to get up at 4 am every day to milk his parents' cows, he managed to obtain an education at the State Teacher's College in Warrensburg. His first job after college was selling correspondence courses. He moved on to selling bacon, soap, and lard（猪油）for Armour&Company.

After saving $500, Dale Carnegie quit sales in 1911 in order to achieve a lifelong dream of becoming a lecturer. He ended up instead attending the American Academy of Dramatic Arts in New York, but found little success as an actor. Later he got the idea to teach public speaking. In his first session, he suggested that students speak about "something that made them angry", and discovered the technique that made speakers unafraid to address a public audience. From its beginning, the Dale Carnegie Course developed. Carnegie had made use of the average American's desire to have more self-confidence.

Perhaps one of Carnegie's most successful marketing moves was to change the spelling of his last name from "Carnagey" to Carnegie, at a time when Andrew Carnegie was a widely recognized name.

Carnegie's works include Lincoln the Unknown (1932), Public Speaking and Influencing Men in Business (1937), and How to Stop Worrying and Start Living (1948). His greatest achievement, however, was when Simon &. Schuster published How to Win Friends and Influence People. The book was a bestseller from 1936. By the time of Carnegie's death, the book had sold five million copies in 31 languages, and there had been 450,000 graduates of his Dale Carnegie Institute.

Carnegie died at his home in New York in 1955.
