Muijs and his family

Elisabeth Muijs-Staal was at the Hollandsche Schouwburg with her daughter Maria and her son Willem Arnold. Her sister and brother-in-law tried to arrange for Elisabeth and her children to be released and contacted Puttkammer, who agreed to buy their freedom in return for jewelry, gold and silver worth at least 15,000 guilders for each person (i.e. 45,000 guilders). Unfortunately the stamps for their release were never issued. Elisabeth Muijs-Staal and her children Maria and Willem Arnold were deported to Sobibor from Westerbork on 18 May 1943. The sister and another child of Elisabeth Muijs-Staal survived the war.
