Michel Butterfield (1674-1722) was a well-reputed Englishman who came to France under the reign of King Louis XIV as a mathematical instrument maker. He became one of the most skilled maker of his time and gave mostly his name to a peculiar pocket sundial, very widespread during hal a century onwards.
He had his Atelier at “Rue Neuve des Fosses, Faubourg Saint Germain” in 1677 and in 1691 “Aux Armes d’Angleterre sur le quai des Morfondes” (Marcelin).
