Johannes Pieter Kroese (1702-1778) was a master clockmaker, orginally from Wuppertal in Germany and active in the Kalverstraat in Amsterdam from 1729 onwards. On May 6, 1755 the shop moved in the Kalverstraat to a site between the Monastery and the Mint, to be precise between the St. Jorissteeg and the Olieslagersteeg, opposite across from the Monastery. He worked together with his son Pieter Kroese. After 1775 his son continued the business under his own name.
