James Braid and the Science of Hypnosis

Mesmerism Before Braid

To understand what Braid did, it helps to understand what came before him, in some detail. Franz Anton Mesmer (1734–1815) had promoted "animal magnetism" from the 1770s: the theory that an invisible universal fluid flowed through all living things, and that illness resulted from blockages in its flow, which a "magnetiser" could correct. His Paris sessions were pure theatre: patients sat around a baquet — a covered wooden tub filled with "magnetised" water, iron filings and protruding bent iron rods — linking hands, while Mesmer, in silk robes, made dramatic passes over their bodies.

In 1784, King Louis XVI appointed a Royal Commission to investigate. Its members included the American diplomat Benjamin Franklin, the chemist Antoine Lavoisier, the astronomer Jean Sylvain Bailly, and the physician Joseph-Ignace Guillotin. Using what were essentially the first blinded, sham-controlled experiments — testing "magnetised" trees and water against inert controls — they reached a devastating verdict: the effects were real, but their cause was imagination and expectation, not any magnetic fluid. This finding is now often celebrated as a founding moment of the controlled clinical trial and the study of the placebo effect. Yet mesmerism did not die — it thrived in Britain in the 1830s and 1840s as popular entertainment, touring theatres and public halls much as Charles Lafontaine's act would in Manchester in 1841.

Two precursors matter here, for honesty's sake, because they show that Braid's later insight had partial antecedents even though he was likely unaware of some of them at the time. The Marquis de Puységur, a disciple of Mesmer, discovered "artificial somnambulism" in 1784 — a lucid, sleep-like trance distinct from natural sleep. And Abbé Faria (José Custódio de Faria, 1756–1819), a Goan Catholic priest, argued in Paris in the 1810s that the trance arose from within the subject's own mind — through concentration and expectancy — not from any external fluid. Faria anticipated the direction Braid would later take, though he emphasised the subject's powers of concentration over suggestion and had little contemporary influence, in France or in Britain.

The 1841 Conversion

On the evening of Saturday 13 November 1841, Braid attended a demonstration of mesmerism at the Manchester Athenaeum given by the travelling Swiss mesmerist Charles Lafontaine (1803–1892), a bearded showman whose act involved rendering subjects apparently impervious to pain — shocking them with a battery or burning them with candles, seemingly without effect. Braid went as a hardened sceptic; he had already been persuaded by a four-part anonymous investigation of animal magnetism in The London Medical Gazette in 1838 that there was no evidence for any magnetic agency. Of that first night he wrote: "I saw nothing to diminish, but rather to confirm, my previous prejudices."

But he went back. At a later demonstration — six nights afterwards, by his own account — one thing arrested his attention: a mesmerised subject was genuinely unable to open his eyelids. Braid recognised this as a real physiological phenomenon and, as he put it, "was anxious to discover the physiological cause of it." That was the turning point. He immediately began experimenting — on himself, on family members and friends, and on consenting patients. Within a week he was already lecturing publicly on his own preliminary findings, a remarkably fast turnaround from sceptical audience member to independent investigator.

Braid's Key Experiments

Within days Braid had his answer, and it had nothing to do with magnetism. His method — the "eye-fixation" technique — is best given in his own words from Neurypnology:

"Take any bright object (I generally use my lancet case) between the thumb and fore and middle fingers of the left hand; hold it from about eight to fifteen inches from the eyes, at such position above the forehead as may be necessary to produce the greatest possible strain upon the eyes and eyelids, and enable the patient to maintain a steady fixed stare at the object."

The prolonged upward stare fatigued the eyes and the nervous system; the eyelids drooped; and a trance-like state followed. In his subjects Braid observed altered sensitivity to pain, changed muscle tone (catalepsy), and heightened responsiveness to suggestion. His explanation was physiological: a "nervous sleep" caused by the exhausting fixation of gaze and attention — not animal magnetism, and not the will of the operator.

The decisive point was that Braid could hypnotise himself. Since there was no operator channelling any fluid into him, the phenomenon had to originate within the subject. This was his experimentum crucis: by reversing the operator–subject relationship and treating the process as subject-internal, he demolished Lafontaine's magnetic claims with a form of Occam's razor. Just a week after the demonstration he was lecturing publicly on his own findings; within nine weeks, by his Liverpool lecture of 22 January 1842, he was reporting on the possibility of pain-free surgery. He presented his work around the British Association for the Advancement of Science's Manchester meeting in June 1842.

Braid's later theoretical refinement was monoideism: the recognition that the essential mechanism was the concentration of the mind upon a single dominant idea. By the late 1840s he had accepted that "hypnotism" was not really sleep at all, and tried to rename the state "monoideism" — but the earlier terminology had already stuck fast, and it is his original vocabulary, not his corrected later term, that survives in ordinary and clinical usage today.

Braid did investigate hypnotism as a surgical anaesthetic, and used it for pain-free procedures as early as January 1842 — more than three years before Esdaile's Indian experiments became widely known. But he was cautious; his primary interest was in hypnotism's broader therapeutic applications, and once effective chemical anaesthesia arrived he became an early advocate of ether as well.

Neurypnology (1843)

Braid's ideas were gathered in Neurypnology; or, the Rationale of Nervous Sleep, Considered in Relation with Animal Magnetism, published in London by John Churchill in 1843. It is regarded as the first book-length treatment of hypnotism. It argued that mesmeric trances were not caused by an occult fluid but were a psycho-physiological state produced by manipulating the subject's own nervous system, and it illustrated the claims with numerous case studies. The book sold well: according to Braid himself (and later his biographer John Milne Bramwell), 800 copies had gone by November 1843, and the first edition was exhausted by 1846.

Here the accuracy-conscious reader must tread carefully, and this is the single most important correction this article makes. Braid coined the English terms "hypnotism," "hypnotise" and "hypnotist" — as abbreviations of his "neuro-hypnotism" and "neurypnology," from the Greek hypnos (sleep). But he did not coin the noun "hypnosis." That word is a later derivative that came into wide use through French usage in the 1880s, roughly two decades after Braid's death; the Oxford English Dictionary in fact records an isolated earlier English use (1876), and some etymologists date a first appearance earlier still — so it is safest to say simply that "hypnosis" is a later back-formation that Braid himself never once wrote.

It is also worth noting that the French magnetist Étienne Félix d'Hénin de Cuvillers had used the cognate French terms hypnotisme and hypnotique as early as 1819–1820, before Braid. But Braid used the terminology independently and, decisively, in a new physiological sense rather than an occult one. Fittingly, Braid was scrupulous about this himself: he said he had "adopted" the term, not invented it, writing to The Lancet in 1845 that "I adopted the term 'hypnotism' … to get rid of the erroneous theory about a magnetic fluid."

What Braid Actually Established

Braid's importance is not that he discovered the trance — mesmerists had induced it for sixty years — but that he studied it scientifically rather than mystically; gave it a reproducible, teachable method that did not depend on the charisma of a "magnetiser"; replaced supernatural claims with a physiological explanation; and anticipated psychosomatic medicine — the recognition that the mind can produce real, measurable changes in the body.

After Braid's death, interest in Britain waned and the centre of research shifted to France. Shortly before he died, Braid sent a manuscript to the French surgeon Étienne Eugène Azam, who introduced his ideas in France; his terms were even translated into French as braidisme. Braid's work fed directly into the great French revival of the 1880s. Jean-Martin Charcot, at the Salpêtrière in Paris, treated hypnosis as a neurological phenomenon linked to hysteria; the rival Nancy School, led by Ambroise-Auguste Liébeault and Hippolyte Bernheim, argued it was a normal phenomenon of suggestion. The two schools clashed bitterly over the mechanism. Bernheim generously acknowledged the debt to earlier pioneers, observing that "suggestion was proposed by Abbé Faria, and was applied by James Braid." A young Sigmund Freud observed Charcot's demonstrations in 1885 and studied with Bernheim and Liébeault at Nancy in 1889; he used hypnosis in his early practice before abandoning it in favour of free association and developing psychoanalysis. So a Kinross-born surgeon sits genuinely near the headwaters of depth psychology — though it would be an overstatement to say Braid "caused" psychoanalysis.

James Esdaile in Bengal

The story has a second Scottish hero. James Esdaile (1808–1859), born in Montrose, Angus, on 6 February 1808, the eldest son of a Church of Scotland minister, trained in medicine at Edinburgh (graduating around 1829–1830) and served the East India Company in Bengal. There, in the 1840s, he used "mesmeric" trance as a surgical anaesthetic. As the historian of hypnotism Alan Gauld summarised it, "Esdaile conducted hundreds of surgeries and reported a 5 percent mortality rate (other techniques had a 50 percent or higher mortality rate)" — a staggering claim in an era before antiseptics. His feats included the removal of enormous scrotal tumours, and his work drew on indigenous Indian trance-induction practitioners; his Hooghly hospital earned the nickname of the "jadoo" (magic) hospital, and the colonial government granted him an experimental mesmeric hospital in Calcutta.

Esdaile and Braid were contemporaries who differed sharply in theory. Braid respected Esdaile's results but rejected his mesmerist framework, stating flatly: "In theory I entirely differ from Dr. Esdaile. He is a Mesmerist – that is, he believes in the transmission of some peculiar occult influence from the operator to the patient." Esdaile's window was brief. Chloroform, demonstrated by yet another Scot — James Young Simpson of Edinburgh — in November 1847, offered reliable, cheap chemical anaesthesia, and mesmeric surgery quickly faded from favour. Esdaile retired to Scotland and then Sydenham, where he died in January 1859. As with Braid's own figures, Esdaile's operation counts vary across sources — 260, 261, "at least 291," or simply "hundreds" — and the honest phrasing preferred here is "hundreds," with mortality falling from roughly 50% to roughly 5%; even contemporary observers and modern historians urge that his self-reported statistics be taken "with a pinch of salt."

Modern Applications

Braid's science is alive in the clinic. Modern clinical hypnotherapy has an evidence base for pain management, anxiety, phobias, smoking cessation and — most robustly — irritable bowel syndrome (IBS). In the UK, gut-directed hypnotherapy is recommended by NICE for refractory IBS. The pioneering evidence came from Professor Peter Whorwell's Manchester group — fittingly, Braid's own city: his landmark 1984 controlled trial in The Lancet found that 76% of patients with severe, refractory IBS improved with hypnotherapy, versus 35% of controls, and his later "Manchester Protocol" work reports response rates of 70–80%. Hypnosis is also used for pain relief in childbirth.

Institutional recognition has followed. The British Medical Association first examined hypnosis in 1892, and in 1955 a BMA subcommittee formally endorsed it as a legitimate therapeutic tool for psychosomatic disorders and pain, noting that "for the past hundred years there has been an abundance of evidence that psychological and physiological changes could be produced by hypnotism." The American Medical Association followed with its own endorsement in 1958, and the American Psychological Association maintains Division 30, the Society of Psychological Hypnosis. Modern neuroscience has vindicated Braid's core insight that this is a real, distinct state. The fMRI study by Heidi Jiang, David Spiegel and colleagues at Stanford (published in Cerebral Cortex in 2016), scanning 57 subjects, found that hypnosis produces characteristic changes in the brain: reduced activity in the dorsal anterior cingulate (part of the brain's "salience network"), increased connectivity between the dorsolateral prefrontal cortex and the insula, and reduced connectivity between the prefrontal cortex and the default-mode network. In other words, a Kinross surgeon's "nervous sleep" turns out to have a visible neural signature after all.

Myths & Facts

Did You Know?

• Braid attended his first mesmerism demonstration intending to expose fraud — and left convinced something real was happening, but for entirely different reasons than the mesmerists claimed.
• He coined 'hypnotism' from the Greek for sleep — then realised it wasn't really sleep, and tried (unsuccessfully) to rename it 'monoideism.' Despite the myth, he never used the word 'hypnosis' itself; that came later from France.
• The 1784 Franklin–Lavoisier commission debunked Mesmer's theory but proved the effects were real — Braid was the first to explain what those real effects actually were.
• Fellow Scot James Esdaile, born in Montrose, performed hundreds of operations in India under mesmeric trance, reporting mortality of about 5% against the 50%-plus of conventional surgery of the era.
• The chain from Braid → Charcot → Bernheim → Freud means a Kinross-born surgeon played a genuine role in the intellectual origins of psychoanalysis.
• Hypnosis is now recognised by the British Medical Association, the American Medical Association and the American Psychological Association as a legitimate clinical tool.
• Braid's own decisive proof against animal magnetism was simple: he could hypnotise himself, with no operator present at all.

Honest Caveats

Braid did not discover the trance. Mesmer, Puységur and Abbé Faria all preceded him by decades; his contribution was scientific explanation and reproducible method, not the initial phenomenon.

Braid coined "hypnotism," not "hypnosis." This is the most important correction in this article. The noun "hypnosis" is a later derivative that entered wide use through French usage in the 1880s, roughly two decades after Braid's death; he never wrote the word himself. It is safest to describe it as a later back-formation rather than crediting a single coiner, since sources disagree on the exact first date (the OED cites 1876; others suggest the 1850s or the 1880s in France).

Neurypnology was published in London by John Churchill in 1843 — not Manchester, not 1841. 1841 is the year of the Lafontaine demonstration that converted Braid; the book itself followed some two years later.

"Fife" versus "Kinross": both appear in sources because of a nineteenth-century boundary change; Kinross-shire is correct for Braid's birth in 1795.

Esdaile's operation counts vary across sources (260, 261, "at least 291," or simply "hundreds"); the honest phrasing used here is "hundreds," with mortality falling from roughly 50% to roughly 5% — and even contemporary observers and modern historians urge that his self-reported statistics be taken "with a pinch of salt."

Freud's use of hypnosis was early and later abandoned; the lineage from Braid through Charcot and Bernheim to Freud is real, but should not be overstated as Braid single-handedly originating psychoanalysis.

Beware overstated web claims: many commercial hypnotherapy sites exaggerate NHS and BMA endorsement. The reliable anchors used in this article are the 1955 BMA report, the 1958 AMA report, and NICE's inclusion of gut-directed hypnotherapy in its IBS guidance.
