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. This was not the value of his entire estate.
