United States Holocaust Memorial Museum Collection, Gift of J. Pierre Loebel Funding Note: The cataloging of this collection has been supported by a grant from the Conference on Jewish Material Claims Against Germany. Dr. J. Pierre Loebel donated this testimony to the United States Holocaust Memorial Museum on Sept. 6, 2010. The document came to the Loebel family because they had extended family in Nieswiez, including Mrs. Loebel's grandfather, Neach Wselubski, who was a prominent citizen. Most of the members of the family were murdered in the Holocaust.
