- Mesmer, Franz Anton
born May 23, 1734, Iznang, Swabiadied March 5, 1815, MeersburgGerman physician.After studying medicine at the University of Vienna, he developed his theory of "animal magnetism," which held that an invisible fluid in the body acted according to the laws of magnetism and that disease was caused by obstacles to the free circulation of this fluid. In Mesmer's view, harmony could be restored by inducing "crises" (trance states often ending in delirium or convulsions). In the 1770s he carried out dramatic demonstrations of his ability to "mesmerize" his patients using magnetized objects. Accused by Viennese physicians of fraud, he left Austria and settled in Paris (1778), where he also came under fire from the medical establishment. Though his theories were eventually discredited, his ability to induce trance states in his patients made him the forerunner of the modern use of hypnosis.

In 1775 Mesmer revised his theory of “animal gravitation” to one of “animal magnetism,” wherein the invisible fluid in the body acted according to the laws of magnetism. According to Mesmer, “animal magnetism” could be activated by any magnetized object and manipulated by any trained person. Disease (human disease) was the result of “obstacles” in the fluid's flow through the body, and these obstacles could be broken by “crises” (trance states often ending in delirium or convulsions) in order to restore the harmony of personal fluid flow. Mesmer devised various therapeutic treatments to achieve harmonious fluid flow, and in many of these treatments he was a forceful and rather dramatic personal participant.Accused by Viennese physicians of fraud, Mesmer left Austria and settled in Paris in 1778. There he continued to enjoy a highly lucrative practice but again attracted the antagonism of the medical profession, and in 1784 King Louis XVI appointed a commission of scientists and physicians to investigate Mesmer's methods; among the commission's members were the American inventor and statesman Benjamin Franklin and the French chemist Antoine-Laurent Lavoisier. They reported that Mesmer was unable to support his scientific claims, and the mesmerist movement thereafter declined.Whatever may be said about his therapeutic system, Mesmer did often achieve a close rapport with his patients and seems to have actually alleviated certain nervous disorders in them. More importantly, the further investigation of the trance state by his followers eventually led to the development of legitimate applications of hypnotism.
