Franklin and Mesmer: an encounter.
In 1784, as the Enlightenment was on the wane, Paris faced a debate in which reason confronted the supernatural and the mysterious. Dr. Mesmer, a graduate of the medical school in Vienna, had been running a "magnetic clinic" based on the belief that magnetic fluid, flowing from the stars, permeated all living beings and that every disease was due to an obstruction in the flow. By manipulating that fluid, he launched the concept of animal as opposed to mineral magnetism and claimed to cure all ills. This got him into trouble with the medical faculty, and in 1778 he emigrated to Paris, creating secret societies all over France. Six years later, mesmerism was considered a threat, possibly deleterious to both mind and body. Louis XVI appointed two commissions to investigate this likely fraud. Dr. Guillotin headed one; the other, made up of five members of the Academy of Sciences, included an astronomer and was headed by Franklin, American Ambassador to France. Both commissions concluded that the success of mesmerism was due to the manipulation of the imagination. Mesmer protested vigorously but in vain. He left France and died in obscurity in 1815.
