Dr. Frank Crane (1861 - 1928) An American presbiterian minister, speaker and columnist, he was a prolific writer of Positive books. Almost as popular as Orison Swett Marden and Charles Haanel, at the beggining of the 20th century, he left dozens of books on success, happiness and prosperity. He wrote in "nuggets", or short one or two page essays on different subjects, put together in the form of books. He left thousand of those nuggets full of wisdom. Some of his books include the Four Minute Essays collection (10 volumes), The Business of Life, The Looking Glass, Human Confessions, Adventures in Common Sense and many others. They are now part of our Timeless Wisdom Collection.
