Dale Carnegie

Born in 1888 in Missouri, Dale Carnegie was an American writer and lecturer who became famous for teaching public speaking, salesmanship, and interpersonal skills. He was born Dale Harbison Carnagey and later changed the spelling of his surname to Carnegie.

He is best remembered for How to Win Friends and Influence People and for building training courses that encouraged people to communicate clearly, handle social situations better, and speak with confidence. His work focused on simple, usable habits rather than theory, which helped make his ideas widely popular.

Carnegie died in 1955, but his books and training programs continued to influence business, leadership, and self-improvement long after his lifetime.
