Mesmerism
Braid became interested in the phenomenon known as mesmerism in November 1841, when he personally observed demonstrations given by the traveling Swiss mesmerist Charles Lafontaine (1803–1892). In particular, he examined the physical condition of Lafontaine's mesmerized subjects and concluded that they were, indeed, in quite a different physical state. Upon reflection, he became convinced that he had discovered the natural psychophysiological mechanism underlying these quite genuine phenomena, and he immediately delivered a series of five public lectures in Manchester that commenced on 27 November 1841.
