Puysegur: Where Hypnosis Actually Began

Mesmer built the theory. Braid supplied the word. The state itself, the calm responsive trance every hypnotist since has worked with, was first described by a retired artillery colonel on his own land in Picardy, in the spring of 1784.

His name was Amand-Marie-Jacques de Chastenet, Marquis de Puysegur, 1751 to 1825. He is barely known in English, and the whole discipline runs on what he noticed that spring.

An aristocrat from an old family, a colonel in the artillery regiment of Strasbourg, with a large estate at Buzancy near Soissons. In 1784 he took Mesmer's course in Paris and came home with animal magnetism, the theory that a physical fluid runs through living bodies and can be redirected by a trained operator.

He then did the thing that made the difference: he treated the people around him, kept notes, and wrote down what happened rather than what was supposed to happen.

Victor Race was a young man in his twenties whose family worked on the estate, ill with an inflammation of the chest. Puysegur magnetised him expecting the standard Mesmeric crisis: convulsions, thrashing, a violent discharge that was supposed to signal the cure.

He got the opposite. Victor went quiet, appeared to sleep, and then began to speak. Fluently. He answered questions, discussed his own illness, and held a conversation more articulate than anything he produced awake. Puysegur called it the tranquil crisis, then magnetic sleep, and finally artificial somnambulism, because it resembled natural sleepwalking.

When Victor woke he remembered none of it. Every element clinicians still describe, focused attention, heightened suggestibility, amnesia on waking, dialogue with an operator, is in those first notes.

That same year, Louis XVI's royal commission examined Mesmer's claims. Its members included Benjamin Franklin, Jean Sylvain Bailly, Antoine Lavoisier, Joseph-Ignace Guillotin, Jean-Baptiste Le Roy, Sallin and Jean Darcet. Their verdict was careful and devastating: the cures were real cures, but there was no evidence for any magnetic fluid, and the effects came from the imagination of the patients.

Puysegur kept using the vocabulary of magnetism all his life. His practice said something else. He introduced the word rapport for the bond between magnetiser and subject, and it is rapport, not fluid, that does the work in his case notes. The centre of gravity moved from physics to the relationship between two people, which is exactly where hypnosis has stayed.

He soon had more patients than hours. His answer was to magnetise a tree on the village green and let people take hold of cords tied to its branches, treating a crowd at once.

The scene is easy to mock and worth taking seriously. A large group, a shared expectation, a fixed object, a man they trusted, and an agreement about what was going to happen. Strip out the fluid and you are looking at a working description of group suggestion, staged eighty years before anyone had that phrase.

Puysegur published his account in 1784, as Memoires pour servir a l'histoire et a l'etablissement du magnetisme animal. It circulated in French, and the English-speaking world largely met the phenomenon secondhand.

In 1841 James Braid, a Scottish surgeon, watched Charles Lafontaine demonstrate magnetism in Manchester, concluded the effects were real but the fluid was not, and coined hypnotism. The state Braid renamed is the state Puysegur described fifty-seven years earlier. A modern English translation of the 1784 memoirs, by Adam Crabtree and Sarah Osei-Bonsu, presents them as the origin point of hypnosis, and that is a fair reading.

So the standard sentence, that Braid invented hypnosis, is a naming credit dressed up as a discovery credit.

Two things, and they are more practical than the history suggests.

First, the trance is ordinary. You enter it driving a familiar road, reading past the end of a page, or half an hour into a repetitive task. Nothing about it is exotic or dangerous in itself, and treating it as a rare altered state mostly gets in the way of using it.

Second, rapport is the active ingredient. Puysegur's results came from a relationship of trust and a shared expectation, not from an operator's power. On your own, that translates into a simple structure: a quiet place, a fixed point of attention, a slow count down from twenty, one clear sentence you want to sit with, and a deliberate return. Ten minutes is plenty.

One limit worth stating plainly. Using trance work on trauma, pain or a diagnosed condition belongs with a trained clinician, not with a book from 1784 or a page on the internet.
