At age 4, Morris Dancyger witnessed the liberation of Auschwitz by Soviet forces. In his 2008 testimony held by the Calgary Jewish Federation and part of the USC Shoah Foundation archive, Morris recalled the moment he and his family realized Soviet troops had entered their barracks. Shortly after liberation, a Soviet military crew filmed Morris revealing his concentration camp tattoo. This historic footage later appeared in the 1945 documentary "Oswiecem" (Auschwitz), which documented evidence of Nazi crimes and atrocities.
