Portrait of Pieter Teyler van der Hulst, 1787, by Wybrand Hendriks (after a painting by Frans Decker, since lost). Pieter Teyler is portrayed both as a financier with his "Intrest Boek" -the "Interest Book" he used to track interest rates and outstanding loans- and also as a collector, with art albums in the background. The portrait hangs in the Smaller Boardroom in Teylers Foundation House.
Pieter Teyler van der Hulst (25 March 1702 – 8 April 1778) was a wealthy Dutch Mennonite merchant and banker, who died childless, leaving a legacy of two million florins (in today's terms: about EUR 80 million) to the pursuit of religion, arts and science in his hometown, that led to the formation of Teyler's Museum.[1] This was not the value of his entire estate. He also founded Teylers Hofje in his name, and made important donations to individuals in the Mennonite community.
