Dale Carnegie was an American lecturer and bestselling author, one of the pioneers in the fields of self-improvement, corporate training, and public speaking guidance.

A poor farmer’s son, Dale Carnegie dreamt of becoming a lecturer ever since his childhood years, but after finding a little success as an actor in the years before the First World War, he went nearly broke.

It was then that he got an idea to teach a course on public speaking which was a success and resulted in the publication of Public Speaking and Influencing Men in Business in 1926.
