Dale Carnegie (1888–1955) was a prominent American writer, lecturer, and the developer of famous courses in self-improvement, salesmanship, corporate training, public speaking, and interpersonal skills. Born on a farm in Missouri, Carnegie was a poor farmer's boy, who parlayed his success in sales into a career as a writer and lecturer. His seminal work, 'The Art of Public Speaking,' cements his reputation as an expert orator and public speaking coach. Carnegie believed in the power of personal development and in fostering leadership qualities among the masses. Apart from 'The Art of Public Speaking,' Carnegie is best known for 'How to Win Friends and Influence People,' a book that remains popular in business and communication skills training. His literary style is characterized by straightforward prose, anecdotal evidence, and a focus on practical steps for self-improvement. At the core of Carnegie's philosophy is the belief that success comes from the ability to communicate effectively, build trust, and inspire others. His influence endures in the Dale Carnegie Training, an organization dedicated to continuing his teaching and methodologies in professional development.
