Charles Francis Haanel

Charles Francis Haanel (May 22, 1866 – November 27, 1949) was an American author, philosopher and a businessman. He is best known for his contributions to the New Thought movement through his book The Master Key System.

Personal life and business career The Haanel family was of Swedish extraction, but had lived in Silesia, Prussia, before emigrating to Canada and thence to the United States.

In St. Louis: History of the Fourth City, the author Walter B. Stevens wrote that "Charles F. Haanel was born in Ann Arbor, Michigan, the son of Hugo and Emeline (Fox) Haanel." He was the fourth of six children. According to Stevens, "The family moved to St. Louis, Missouri when Charles was a child. His first job was as an office boy for the National Enameling & Stamping Company in St. Louis, and he worked for this firm in varying capacities for fifteen years before striking out on his own as a writer and businessman."

In 1885 he married Esther M. Smith. They had one son and two daughters. In 1891 his wife died. In 1908 he married for the second time, to Margaret Nicholson of St. Louis, whose father was W. A. Nicholson. and a supporter of the Missouri Athletic Club.

Influence on other writers In 1919, Napoleon Hill wrote Haanel a letter thanking him for The Master Key System. In the letter Hill stated, "My present success and the success which has followed my work as President of the Napoleon Hill Institute is due largely to the principles laid down in The Master-Key System."

Haanel was quoted in the best-selling self-help book The Secret by Rhonda Byrne, published in 2007.

Actor and former football player Terry Crews has said about The Master Key System, "I have read hundreds of personal development books, but this is the one that clearly showed me how to visualize, contemplate, and focus on what I truly wanted. It revealed to me that we only get what we desire most, and to apply myself with a laserlike focus upon a goal, task or project. That in order to 'have', you must 'do', and in order to 'do', you must 'be' - and this process is immediate. [...] I also reread it probably once a month to keep my vision clear."
