The History of Hypnosis: From James Braid to Modern Times
Hypnosis has a longer, stranger history than most people realize, running from 18th-century Vienna through a Paris hospital to a psychiatrist's office in Arizona.
Franz Mesmer and "animal magnetism"
In the late 1700s, Austrian physician Franz Mesmer proposed that an invisible force he called "animal magnetism" flowed through the body and could be manipulated to treat illness. His dramatic sessions, complete with dim rooms and iron rods, produced real results in some patients. A French royal commission later concluded the effects came from imagination and suggestion, not any physical force. He was more right than the commission gave him credit for. He had stumbled onto the power of suggestion, just with the wrong explanation for it.
James Braid and the birth of the word "hypnosis"
Scottish surgeon James Braid studied these trance states in the 1840s and rejected the "magnetism" theory entirely. He proposed a neurological explanation instead: focused attention and fatigue of the eye muscles could produce the state, which he named "hypnosis," from the Greek "hypnos" for sleep, even though he later realized the state was not sleep at all. Braid's work moved the field from mysticism toward something closer to psychology and physiology.
Charcot, Freud, and the shift toward psychology
Later in the 19th century, French neurologist Jean-Martin Charcot studied hypnosis at the Salpêtrière hospital in Paris, connecting it to his research on hysteria. A young Sigmund Freud attended Charcot's lectures and used hypnosis early in his career before moving toward free association and psychoanalysis. Hypnosis had, by this point, become a subject serious clinicians took seriously, not only a stage curiosity.
Milton Erickson and modern hypnotherapy
In the 20th century, American psychiatrist Milton Erickson reshaped the field again, developing a conversational, indirect style of hypnosis built around the individual rather than a fixed script. His approach influenced most of modern clinical hypnotherapy, including the emphasis on tailoring language to the person in front of you rather than reciting a generic induction.
Where it stands today
Hypnotherapy is now recognized by professional bodies such as the General Hypnotherapy Register in the UK, and it shows up in mainstream medical settings for pain management, anxiety, and habit change. The tools have moved from iron rods and dim Parisian lecture halls to structured audio sessions you can use from home, but the underlying idea, that focused attention can change how the subconscious responds, has stayed remarkably consistent for over two centuries.
