Responding to Mesmer’s growing notoriety, the Medical Faculty of Paris became alarmed, and urged the King to appoint a blue-ribbon committee of inquiry. The committee included Benjamin Franklin, Antoine Laurent Lavoisier, Michael Joseph Majault, Jean Sylvain Bailly, Jean d'Arcet. Finding no evidence of a magnetic fluid, these scientists attributed the power of mesmerism to the “imagination” and so drove Mesmer from Paris. Lavoisier may have been the author of the report.
