Hidden away in a modern library are the remains of one of the 18th century’s most celebrated wunderkammers. The aristocrat Joseph Bonnier de La Mosson didn’t just inherit an incredible fortune, he also inherited a lavish residence with the Hôtel du Lude on the ritzy Boulevard Saint-Germain. With an intense interest in science, it was there he created his cabinet of curiosity, which encompassed objects related to anatomy, chemistry, physics, mechanical devices, optic machines, fine art, and natural history, many of which he collected on his world travels.
