Animal magnetism, also known as mesmerism, was the name given by the German doctor Franz Friedrich Anton Mesmer in the 18th century to what he believed to be an invisible natural force exerted by animals. He believed that the force could have physical effects, including healing. He tried persistently but without success to achieve scientific recognition of his theories.
The theory attracted numerous followers in Europe and the United States and was popular into the 19th century. Practitioners were often known as magnetizers. For about 75 years from its beginnings in 1779 it was an important speciality in medicine, and continued to have some influence for about another 50 years. Hundreds of books were written on the subject between 1766 and 1925. Today it is almost entirely forgotten.
Mesmerism is still practised as a form of alternative medicine in some countries, but magnetic practices are not recognized as part of medical science.

Etymology and definitions
The terms "magnetizer" and "mesmerizer" have been applied to people who study and practice animal magnetism. These terms have been distinguished from "mesmerist" and "magnetist", which are regarded as denoting those who study animal magnetism without being practitioners; and from "hypnotist", someone who practises hypnosis.
The etymology of the word magnetizer comes from the French "magnetiseur" ("practicing the methods of mesmerism"), which in turn is derived from the French verb magnetiser. The term refers to an individual who has the power to manipulate the "magnetic fluid" with effects upon other people present that were regarded as analogous to magnetic effects. This sense of the term is found, for example, in the expression of fr:Antoine-Joseph Gorsas: "The magnetizer is the imam of vital energy".
A tendency emerged amongst British magnetizers to call their clinical techniques "mesmerism"; they wanted to distance themselves from the theoretical orientation of animal magnetism that was based on the concept of "magnetic fluid". At the time, some magnetizers attempted to channel what they thought was a magnetic "fluid", and sometimes they attempted this with a "laying on of hands". Reported effects included various feelings: intense heat, trembling, trances, and seizures.
Many practitioners took a scientific approach, such as Joseph Philippe François Deleuze (1753–1835), a French physician, anatomist, gynecologist, and physicist. One of his pupils was Théodore Léger (1799–1853), who wrote that the label "mesmerism" was "most improper". (Léger moved to Texas around 1836).
Noting that, by 1846, the term "galvanism" had been replaced by "electricity", Léger wrote that year:
Mesmerism, of all the names proposed [to replace the term animal magnetism], is decidedly the most improper; for, in the first place, no true science has ever been designated by the name of a man, whatever be the claims he could urge in his favor; and secondly, what are the claims of Mesmer for such an honor? He is not the inventor of the practical part of the science, since we can trace the practice of it through the most remote ages; and in that respect, the part which he introduced has been completely abandoned. He proposed for it a theory which is now [viz., 1846] exploded, and which, on account of his errors, has been fatal to our progress. He never spoke of the phenomena which have rehabilitated our cause among scientific men; and since nothing remains to be attributed to Mesmer, either in the practice and theory, or the discoveries that constitute our science, why should it be called mesmerism?
In 1784 a French Royal Commission appointed by Louis XVI studied Mesmer's magnetic fluid theory to try to establish it by scientific evidence. The commission included Majault, Benjamin Franklin, Jean Sylvain Bailly, J. B. Le Roy, Sallin, Jean Darcet, de Borey, Joseph-Ignace Guillotin, Antoine Lavoisier, Poissonnier, Caille, Mauduyt de la Varenne, Andry, and de Jussieu.
Whilst the commission agreed that the cures claimed by Mesmer were indeed cures, it also concluded there was no evidence of the existence of his "magnetic fluid", and that its effects derived from either the imaginations of its subjects or charlatanry.
The Royal Academy investigation
A second investigating committee, appointed by a majority vote in 1826 in The Royal Academy of Medicine in Paris, studied the effects and clinical potentials of the mesmeric procedure - without trying to establish the physical nature of any magnetic fluidum. The report says:
...what we have seen in the course of our experiments bears no sort of resemblance to what the Report of 1784 relates with regard to the magnetizers of that period. We neither admit nor reject the existence of the fluid, because we have not verified the fact ; we do not speak of the baquet ... nor of the assemblage of a great number of people together, who were magnetized in the presence of a crowd of witnesses ; because all our experiments were made in the most complete stillness ... and always upon a single person at a time. We do not speak of ... the crisis
Among the conclusions were:
Magnetism has taken effect upon persons of different sexes and ages. ... In general, magnetism does not act upon persons in a sound state of health. ... Neither does it act upon all sick persons.
... we may conclude with certainty that this state exists, when it gives rise to the development of new faculties, which have been designated by the names of clairvoyance; intuition; internal prevision; or when it produces great changes in the physical economy, such as insensibility; a sudden and considerable increase of strength; and when these effects cannot be referred to any other cause.
... We can not only act upon the magnetized person, but even place him in a complete state of somnambulism, and bring him out of it without his knowledge, out of his sight, at a certain distance, and with doors intervening.
... The greater number of the somnambulists whom we have seen, were completely insensible ... we might pinch their skin, so as to leave a mark, prick them with pins under the nails, &c. without producing any pain, without even their perceiving it. Finally, we saw one who was insensible to one of the most painful operations in surgery, and who did not manifest the slightest emotion in her countenance, her pulse, or her respiration.
... Magnetism is as intense, and as speedily felt, at a distance of six feet as of six inches; and the phenomena developed are the same in both cases.
...Magnetism ought to be allowed a place within the circle of medical sciences...
Mesmerism and hypnotism
Abbé Faria was one of the disciples of Franz Anton Mesmer who continued with Mesmer's work following the conclusions of the Royal Commission. In the early 19th century, Abbé Faria is said to have introduced oriental hypnosis to Paris, and to have conducted experiments to prove that "no special force was necessary for the production of the mesmeric phenomena such as the trance, but that the determining cause lay within the subject himself"—in other words, that it worked purely by the power of suggestion.
Hypnotism, a designation coined by the Scottish surgeon, James Braid, originates in Braid's the response to an (1841) exhibition of "animal magnetism", by Charles Lafontaine, in Manchester. Writing in 1851, Braid was adamant that, in the absence of the sorts of "higher phenomena" reportedly produced by the mesmerists,
…and in contra-distinction to the Transcendental [i.e., metaphysical] Mesmerism of the Mesmerists … [allegedly] induced through the transmission of an occult influence from [the body of the operator to that of the subject,] Hypnotism, [by which] I mean a peculiar condition of the nervous system, into which it can be thrown by artificial contrivance … [a theoretical position that is entirely] consistent with generally admitted principles in physiological and psychological science [would] therefore [be most aptly] designated Rational Mesmerism.
The vital fluid and animal magnetism
A 1791 London publication explains Mesmer's theory of the vital fluid :
"Modern philosophy has admitted a plenum or universal principle of fluid matter, which occupies all space; and that as all bodies moving in the world, abound with pores, this fluid matter introduces itself through the interstices and returns backwards and forwards, flowing through one body by the currents which issue therefrom to another, as in a magnet, which produces that phenomenon which we call Animal Magnetism. This fluid consists of fire, air and spirit, and like all other fluids tends to an equilibrium, therefore it is easy to conceive how the efforts which the bodies make towards each other produce animal electricity, which in fact is no more than the effect produced between two bodies, one of which has more motion than the other; a phenomenon serving to prove that the body which has most motion communicates it to the other, until the medium of motion becomes an equilibrium between the two bodies, and then this equality of motion produces animal electricity."
According to an anonymous writer of a series of letters published by the editor John Pearson in 1790, animal magnetism can cause a wide range of effects ranging from vomiting to what is termed the "crisis." The purpose of the treatment (inducing the "crisis") was to shock the body into convulsion in order to remove obstructions in the humoral system that were causing sicknesses. Furthermore, this anonymous supporter of the animal magnetism theory purported that the "crisis" created two effects: first, a hypnotic state in which the patient would be "possessed of his senses, yet cease to be an accountable creature", and second, so-called "unobstructed vision" which would allow the hypnotized subject to see through objects. A patient under crisis was believed to be able to see through the body and find the cause of illness, either in themselves or in other patients.
The Marquis of Puységur's miraculous healing of a young man named Victor in 1784 was attributed to, and used as evidence in support of, this "crisis" treatment. The Marquis was allegedly able to hypnotize Victor and, while hypnotized, Victor was said to have been able to speak articulately and diagnose his own sickness.
Jacob Melo discusses in his books some mechanisms by which the perceived effects of animal magnetism have been claimed to operate.
Social skepticism in the Romantic Era
The study of animal magnetism spurred the creation of the Societies of Harmony in France, where members paid to join and learn the practice of magnetism. Doctor John Bell was a member of the Philosophical Harmonic Society of Paris and was certified by the society to lecture and teach on animal magnetism in England. The existence of the societies transformed animal magnetism into a secretive art. Practitioners and lecturers did not reveal the techniques of the practice based on the society members having paid for instruction, and the idea that it was unfair to reveal the practice to others for free. Although the heightened secrecy of the practice contributed to the skepticism about it, many supporters and practitioners of animal magnetism touted the ease and possibility for everyone to acquire the skills to perform its techniques.
The popularization of animal magnetism was denounced and ridiculed by newspaper journals and theatre during the Romantic Era. Many deemed animal magnetism to be nothing more than a theatrical falsity or quackery. In a 1790 publication, an editor presented a series of letters written by an avid supporter of animal magnetism and included his own thoughts in an appendix stating: "No fanatics ever divulged notions more wild and extravagant; no impudent empiric ever retailed promises more preposterous, or histories of cures more devoid of reality, than the tribe of magnetisers." 
The novelist and playwright Elizabeth Inchbald wrote the farce Animal Magnetism in the late 1780s. The plot revolved around multiple love triangles and the absurdity of animal magnetism. The following passage mocks the medical prowess of those qualified only as mesmerists:
Doctor: They have refused to grant me a diploma—forbid me to practice as a physician, and all because I don't know a parcel of insignificant words; but exercise my profession according to the rules of reason and nature; Is it not natural to die, then if a dozen or two of my patients have died under my hands, is not that natural? …
Although the doctor's obsession with the use of animal magnetism, not merely to cure but to force his ward to fall in love with him, made for a humorous storyline, Inchbald’s light-hearted play commented on what society perceived as threats posed by the practice.
De Mainanduc brought animal magnetism to England in 1787 and promulgated it into the social arena. In 1785, he had published proposals to the ladies of Britain to establish a "hygean society" or society of health, by which they would pay to join and enjoy his treatments. As both popularity and skepticism increased, many became convinced that animal magnetism could lead to sexual exploitation of women. Not only did the practice involve close personal contact via the waving of hands over the body, but people were concerned that the animal magnetists could hypnotize women and direct them at will.
The French revolution catalyzed existing internal political friction in Britain in the 1790s; a few political radicals used animal magnetism as more than just a moral threat but also a political threat. Among many lectures warning society against government oppression, Samuel Taylor Coleridge wrote:
William Pitt, the great political Animal Magnetist, ... has most foully worked on the diseased fancy of Englishmen ... thrown the nation into a feverish slumber, and is now bringing it to a crisis which may convulse mortality!
Major politicians and people in power were accused by radicals of practising animal magnetism on the general population.
In his article "Under the Influence: Mesmerism in England", Roy Porter notes that James Tilly Matthews suggested that the French were infiltrating England via animal magnetism. Matthews believed that "magnetic spies" would invade England and bring it under subjection by transmitting waves of animal magnetism to subdue the government and people. Such an invasion from foreign influences was perceived as a radical threat.
Mesmerism and spiritual healing practices
Today scholars[who?] believe mesmerism to share a concept of life force or energy with such Asian practices as reiki and qigong. However, the practical and theoretical positions of such practices are on whole substantially different from those of mesmerism.
During the Romantic period, mesmerism produced enthusiasm and inspired horror in the spiritual and religious context. Though discredited as a credible medical practice by many, mesmerism created a venue for spiritual healing. Some animal magnetists advertised their practices by stressing the "spiritual rather than physical benefits to be gained from animal magnetism" and were able to gather a good clientele from among the spiritually inspired population.
Many researchers, among them Protestants, spiritists, and other writers, claim that Jesus was the greatest of all magnetizers, and that the source of his miracles was animal magnetism. Mary Baker Eddy, the founder of Christian Science, claimed on the other hand that animal magnetism has no remedial power and that its effects "lead to moral and to physical death." 
Sporadic research into animal magnetism was conducted in the 20th century, and the results published; for example, B. Grad wrote three papers related to the subject between 1961 and 1976.
In the Classical era of animal magnetism, the late 17th century to the mid-19th century, there were professional magnetizers, whose techniques were described by authors of the time as particularly effective. Their method was to spend prolonged periods "magnetizing" their customers directly or through "mesmeric magnets". It was observed that in some conditions, certain mesmerizers were more likely to achieve the result than others, regardless of their degree of knowledge.
