Dale Carnegie

Dale Carnegie was born Dale Breckenridge Carnagey on a Missouri farm in 1888 and worked his way through college before a string of unsuccessful sales jobs and a failed attempt at acting. His break came almost by accident: teaching a public-speaking class at a New York YMCA in exchange for a cut of the tuition, he ran out of prepared material on the first night and improvised by asking students to speak about something that had genuinely angered them — and found they spoke far more confidently about material they actually cared about.

That improvisation became the seed of Dale Carnegie Training, an organization built on public speaking, salesmanship, and interpersonal skills that still operates internationally today. Carnegie spent years refining the material through direct feedback from thousands of adult students before distilling it into How to Win Friends and Influence People (1936), which became one of the best-selling nonfiction books ever published. He followed it in 1948 with How to Stop Worrying and Start Living, a companion volume on managing anxiety that became nearly as influential.

He died of Hodgkin lymphoma in 1955, but the training organization and the underlying idea — that lasting influence comes from genuine attention and respect for other people, not argument or authority — outlived him by decades and remains one of the most widely cited premises in popular self-help and business writing.
