Documents were discovered by Grete Mares among her personal papers. Because some were addressed to her mother, Berta Rosenzweig, during the Holocaust, Ms. Mares removed them for donation to United States Holocaust Memorial Museum. No information on the creators of the materials is available to United States Holocaust Memorial Museum Archives.
