Simon Heinrich Sack (27 June 1723 in Hecklingen – 2 December 1791 in Glogau) was Hofrat (Privy Councilor), Justice Commissioner and adviser to King Frederick II of Prussia.
He accumulated considerable wealth in this capacity with which he founded the Privy Councillor Simon Heinrich Sack Family Foundation in Prussia and which still exists to this day.
[1] After studying law at the University of Frankfurt an der Oder, he was employed by the District Authority of Glogau as barrister at the age of 19.
This became a subject of much dispute because the Graf of Hoym had calculated that should the money continue to gain interest the funds would reach 1,083,168,426 Taler after 200 years and would thus be more than the whole of the capital of the State of Prussia.
[9] Many records and works of art relating to Simon Heinrich Sack and his descendants are to be found with the Prussian Museum in Wesel and Minden, Germany, including the famous painting of Luise von Mecklenburg-Strelitz (1776-1810), wife of Friedrich Wilhelm III.
