Nate Leipciger was born in 1928 in Chorzów, Poland. He grew up with his parents and sister, but this all changed when World War II engulfed Poland. Nate survived 7 different concentration camps during the Nazi occupation from the age of 11, additionally surviving 2 ghettos. He and his family were transferred to Auschwitz when he was fifteen, after which he would never see his mother or sister again.
In May 1945, Nate and his father were liberated. Seeking a fresh start in 1948, they immigrated to Canada, reuniting with his father's only surviving brother, who had lived in Canada since 1912. Following the war, despite the things he had suffered, Nate rebuilt his life. He became a successful engineer and started a family with his wife, later having three children. Nate became an influential figure in Holocaust education, actively engaging and contributing to organizations such as the Toronto Holocaust Remembrance Committee, the Canadian Jewish Congress, the Neuberger Holocaust Education Centre, and the International Council to the Museum of Auschwitz-Birkenau.
Nate wrote his memoir The Weight of Freedom in 2015. He not only educated people about his experiences of the Holocaust but also highlighted his childhood experiences with Jewish food. One memory he shared was one as a child helping the baker's son brush challah with egg white after it came out of the oven, and how he often received a pastry as a thank you for helping. His commitment to education was further shown in 2016 when he guided Canadian Prime Minister Justin Trudeau through Auschwitz-Birkenau, teaching the importance of remembrance.
