The creation of a distinct concept of hypnosis owes its existence mostly to a charismatic 18th century healer named Franz Anton Mesmer (1734-1815).
Mesmer had a deep interest in Paracelsan astrological principles, and the supposed direct influence of heavenly bodies on human health, by means of what were believed by Mesmer and others to be measurable physical forces (as opposed to the subtle forces of later occult doctrines interpreting Mesmerism).
