The Scottish surgeon who turned mystical mesmerism into a clinical science

In short: In 1841, James Braid watched a travelling showman claim to use magnetic fluids to control minds. Braid, a skeptical surgeon, suspected a physiological trick. By experimenting on himself, he stripped away the occult, proving that hypnosis was not magic, but a natural, internal state of the human brain.

James Braid, born in 1795, was a respected Scottish surgeon who built a successful practice in Manchester. Before his fascination with hypnosis, he was already a skilled operator, having performed hundreds of surgeries for conditions like clubfoot and strabismus. His transition into the study of the mind began in November 1841, when he attended a demonstration by the French magnetist Charles Lafontaine. While many contemporaries dismissed such displays as pure fraud, Braid observed a genuine physical reaction—the inability of a subject to open their eyelids—that he believed warranted scientific investigation.

Braid rejected the prevailing theory of 'animal magnetism,' which suggested that an invisible fluid passed from operator to patient. Applying Occam's Razor, he proposed that the phenomena were instead rooted in the subject's own nervous system. He famously demonstrated this through self-experimentation, inducing a trance-like state by staring at an object until his eyes fatigued. He coined the term 'hypnotism' in his 1843 book, Neurypnology, arguing that the effect was an internal, physiological process rather than an external influence. He viewed it as a valuable, though not universal, medical tool for treating nervous disorders.

His work faced intense hostility, most notably from the cleric Hugh Boyd M'Neile, who publicly denounced Braid’s research as 'satanic agency' in an 1842 sermon. Despite such opposition and the rejection of his papers by the British Association for the Advancement of Science, Braid persisted. He maintained that hypnosis was a legitimate, albeit misunderstood, medical intervention. Today, he is widely regarded as the father of modern hypnotism, having successfully divorced the practice from the occult and grounded it in the study of the brain and spinal cord.
