Holocaust survivor Minna Aspler -- who spent time in the Warsaw Ghetto -- recalls the personality of Emanuel Ringelblum, who had been her history teacher. Ringelblum went on to lead a clandestine effort with other Warsaw Ghetto inhabitants to amass an archive that would eventually shine a light on the atrocities that occurred there. Aspler's testimony, recorded by McGill University in Montreal in 1995, is stored in USC Shoah Foundation's Visual History Archive.

Dorothy Zoltek, a Warsaw Ghetto and Holocaust survivor, said she knew Emanuel Ringelblum's family well. She discusses their relationship in this testimony, recorded in 1985 by the Sarah and Chaim Neuberger Holocaust Education Centre in Toronto. The testimony is stored in USC Shoah Foundation's Visual History Archive.
