Isak Cieply was born on February 1, 1924 in Starachowice, Poland. He had five siblings and the family was very poor. In the fall of 1939, soon after the German invasion, the Jews of Starachowice were ordered to move into the ghetto. Isak was selected to work in a steel factory and his work pass protected him from round-ups. At the beginning of 1943 he was sent to the Bugaj camp to work in a supplies warehouse. In the summer of 1944 the camp was liquidated after rumours of the approach of the Soviet army had spread. The prisoners were taken to Auschwitz. Isak was sent to work in an electric supplies warehouse in Buna/Auschwitz III. There he met a German soldier who proposed a deal that Isak accepted. Isak was to supply this soldier with electric materials and, in return, he would get a loaf of bread every day. In January 1945 Isak was sent on a death march to the Flossenbürg concentration camp. Sometime later he was sent on another death march but succeeded to escape with some fellow prisoners. They eventually met American soldiers. After liberation Isak worked as the chief supplier of the Pfarrkirchen and Eggenfelden DP camps. He immigrated to Canada in 1948 and married the late Regina Cieply who was also a survivor. They had four children and several grandchildren, among them Jamie Benizri.
