signed and sealed his will (Latin: testament) on November 27th, 1607. The original was lost during the Thirty Years' War either in the Sack of Magdeburg or through intential criminal destruction. Handwritten copies of the will and the original of an inventory of the heritage of Nicolaus dated June 6th, 1611, are preserved in the Salzwedel city archive to this day. These documents were written by the notary public Petrus Schultze of Altenhausen, whose sons authenticated and sealed the copies in 1654 in the presence of Sebastian Gercken, a foundation counsellor. The sealed original of a debt obligation from 1649 by the city of Magdeburg to Sebastian is also preserved in the Salzwedel city archive. In 1865 a statute was formalized, which defines the decision processes within the foundation. It is valid in modernized form to this day
