Gerard van Loon

Baptism date: 
January 17, 1683
Burial date: 
August 29, 1758

His family owned the extensive bewery, the Verkeerde Wereld, on the east side of the Brabanste Turfmarkt. Loon was educated at Leuven, where he was a student of the Jansenist Antony Cink, and at Leiden.

He was a lawyer and numismatist who wrote several historical studies, including in 1731 a comprehensive, illustrated study of Dutch historical coins and medals that is still a standard reference work.

In 1716, Leeuwenhoek addressed one of the Send-Brieven to the 32-year-old Loon. It was about hops, a topic related to both of their families. It is dated a month before Leeuwenhoek received a medal from the faculty at Leuven, handed over to him by Loon in the presence of Delft notary Jacob van der Werff.
