Armand François Louis de Mestral de Saint-Saphorin

Armand François Louis de Mestral de Saint-Saphorin was an 18th-century Swiss diplomat whose historical significance is tied to a Michelangelo drawing that he acquired, which remained in his family for over 200 years before being sold at auction for a record price. His ownership of the artwork contributed to its provenance and ultimately its extraordinary value at the recent Christie’s auction.
