James Braid and the birth of the word hypnosis
James Braid’s 1843 Neurypnology broke with animal magnetism and introduced a nervous-sleep account that gave English its word hypnosis.

James Braid (c. 1795–1860), a Scottish surgeon working in Manchester, is the usual credit for bringing hypnosis into English medical vocabulary. The move was a break with Mesmer, not a rebrand of magnetic fluid.
Key evidence
In 1843 Braid published Neurypnology; or, The rationale of nervous sleep (London: J. Churchill). The book is public domain; the scan above is the 1843 Churchill edition.
Braid argued that the phenomena he saw after prolonged visual fixation were a nervous (physiological) state, not an occult fluid. He illustrated the method with case reports of symptom relief; typical of his century, not of a CONSORT trial.
The Mesmer / 1784 story is the contrast: fluid versus nervous sleep. Later French neurology (Charcot) took hypnosis in another direction again.
Limitations
Naming a procedure is not the same as proving every later clinical claim. Braid’s “cures” cannot be pooled with later randomised trials.
What we don't know yet
How closely Braid’s 1840s induction matches any one modern school (Ericksonian, laboratory, stage) is a historian’s argument, not a measurement.
