This conundrum – does hypnosis have a real, physical basis, or not? Important shifts were happening elsewhere, however. First of all, the centre of hypnotic gravity moved from Europe to America, where all the most significant breakthroughs of the 20th century took place.
Secondly, hypnosis became a popular phenomenon, something that was increasingly available to the layman, outside of the laboratory or clinic.
Nevertheless, the stubborn fact remained that hypnosis worked, and the 19th Century is characterised by individuals seeking to understand and apply its effects.
Surgeons and physicians like John Elliotson and James Esdaille pioneered its use in the medical field, risking their reputation to do so, whilst researchers like James Braid began to peel away the obscuring layers of mesmerism, revealing the physical and biological truths at the heart of the phenomenon.
Mesmer was also the first to develop a consistent method for hypnosis, which was passed on to and developed by his followers. Mesmer himself, for instance, liked to perform mass inductions by having his patients linked together by a rope, along which his “animal magnetism” could pass.
