Société Royale de Médecine to Benjamin Franklin, January 1, 1781
The Société Royale de Médecine invites Benjamin Franklin to witness demonstrations of innovative garments designed by M. le Roux, including one that restores perspiration, another that allows safe handling of hazardous materials, and a flotation suit aiding in cold-water rescues. These experiments aim to prove that even non-swimmers can safely save drowning individuals. The event is scheduled for March 10, 1783, at the Bains Chinois on Île Saint-Louis in Paris.
