Franz Mesmer: Biography, Achievements & Lasting Legacy

Franz Anton Mesmer ( MEZ-mər; German: [ˈmɛsmɐ]; 23 May 1734 – 5 March 1815) was a German physician with an interest in astronomy. He theorized the existence of a process of natural energy transference occurring between all animate and inanimate objects; this he called "animal magnetism", later referred to as mesmerism. Mesmer's theory attracted a wide following between about 1780 and 1850, and continued to have some influence until the end of the 19th century. In 1843, the Scottish doctor James Braid proposed the term "hypnotism" for a technique derived from animal magnetism; today the word "mesmerism" generally functions as a synonym of "hypnosis". Mesmer also supported the arts, specifically music; he was on friendly terms with Haydn and Mozart.
