Heiman Herman de Leeuw

In 2005 a mass grave from WW II was found at the Stuttgart airport. Heiman Herman de Leeuw is possibly among the thirteen Dutch Jews buried here. He was one of the Jewish prisoners at Kommando Echterdingen, near to concentration camp Natzweiler, who was set to work on the airport of Stuttgart late 1944. The remains have been properly reburied.

We have been unable to determine whether one or more members of this family survived the war. While their names do not appear on the lists of survivors, we have not been able to trace them in In Memoriam either. They are therefore labeled as 'surviving' and their names are not listed.
