Experts can’t agree on whether [Franz Anton Mesmer](https://www.britannica.com/biography/Franz-Anton-Mesmer) (1734-1815) was a quack or a genius, but all concede that the [Swabian](https://www.merriam-webster.com/dictionary/swabian) physician's name is the source of the word mesmerize. In his day, Mesmer was the toast of Paris, where he enjoyed the support of notables including Queen Marie Antoinette. He treated patients with therapeutic procedures (called, appropriately enough, [mesmerism](https://www.merriam-webster.com/dictionary/mesmerism)) involving what he claimed was a mysterious force termed animal magnetism. (Many believe that mesmerism was what we now call [hypnotism](https://www.merriam-webster.com/dictionary/hypnotism)). Accordingly, the verb mesmerize was first used to mean "to subject to mesmerism" before broadening to be synonymous with [hypnotize](https://www.merriam-webster.com/dictionary/hypnotize), and later to mean "to amaze or captivate."
