Coue, Emile: - mile Cou de la Ch taigneraie was a French psychologist, pharmacist, and hypnotist, best known for developing the method of autosuggestion, which became a key approach to psychotherapy and self-improvement in the early 20th century. Born in Troyes, France, in 1857, Cou initially worked as a pharmacist, but his interest in psychology and the mind led him to explore the power of suggestion in healing. He developed the technique of autosuggestion, where individuals repeat positive affirmations to influence their subconscious mind and achieve better physical, emotional, and mental well-being. This method became widely recognized and highly influential in both Europe and America during his lifetime. Cou believed in the power of the human mind to influence physical health and overall happiness, a view that was groundbreaking at the time. He authored several books on the subject, sharing his theories with the public. He passed away in 1926 at the age of 69 in Nancy, France. Cou s work continues to inspire self-help techniques and positive thinking practices used by people seeking personal growth and transformation. He was married to Lucie Lemoine in 1884.
