Johann Philipp Graumann (born in 1706^[1] – died 22 April 1762 in Berlin) was a German business mathematician,^[2][3] an expert on exchange rates and coinage, mint master in Braunschweig-Wolfenbüttel and Berlin, a mercantilist, and Prussian financial advisor. He is considered one of the most important German monetary theorists of his time.^[4] As master of the mints in Prussia, he implemented a major coin reform, with the goal of implementing a new monetary standard to promote trade, increase seigniorage income and elevate the Prussian coins to the status of a reserve currency.^[5] Graumann was portrayed by his contemporaries as a dreamer. With only a slight modification, his coin standard remained in place in Germany until 1907.
