Émile Coué (* February 26, 1857 in Troyes; † July 2, 1926 in Nancy) was a French pharmacist and author as well as the founder of modern, conscious autosuggestion.
Coué studied the work on hypnosis by Ambroise Liébault and Hippolyte Bernheim (Nancy School or Nancy School of Hypnosis). As a pharmacist, he got the impression that a positive comment when customers picked up their medicine enhanced the effect. After further studies, he began to put his views on suggestion into practice.
