The Herschkowitz family papers were donated by Brenda Herschkowitz Levenson to the United States Holocaust Memorial Museum in 1995, 2001 and 2002. These collections were given separate accession numbers at the time of their donation: 1995.A.0581, 2001.301.1, and 2002.259 respectively. These accessions have since been unified, and can be located under one accession number: 1995.A.0581.
