Étienne Félix d'Henin de Cuvillers explained

Étienne Félix d'Henin de Cuvillers (1755–1841) was a French magnetizer and an early practitioner of mesmerism as a scientific discipline.^[1] He's best known for coining the term hypnotism.

Hénin de Cuvillers was a follower of Franz Anton Mesmer (1734–1815). However, unlike Mesmer he did not believe in the existence of a "magnetic fluid" in animal magnetism, and instead emphasized the role of mental processes in mesmerism. In his book French: Le magnétisme éclairé (The Enlightened Magnetism), he describes accounts of mesmeric effects in terms of belief and suggestibility.^[2]

He is credited for popularizing a system of scientific nomenclature by using the prefix "French: hypn" in words such as French: hypnotique (hypnotic), French: hypnotisme (hypnotism) and French: hypnotiste (hypnotist). He used these terms as early as 1820, and is believed by many to have coined these names. In 1820 he became editor of the French: Archives du Magnetisme Animal (Archives of Animal Magnetism).^{[3] [4]}
