Oscar Zaretsky survived the Holocaust by Bullets in eastern Poland. He and his siblings were orphaned when the Germans invaded the Soviet Union, and they were forced to spend many months alone in the forests, perilously clinging to life. After the war, Oscar came to Canada as a refugee and was adopted by the Zaretsky family in Winnipeg. He settled in Toronto and built a family and career. Oscar’s life is an inspiring story about catastrophe, perseverance, luck, and survival. His history is told by his grandson, Samuel Buckstein. Samuel Buckstein has been involved in Holocaust education for over fifteen years and joined the Carrying Holocaust Testimony project in 2019. Sam develops and consults on renewable energy projects. Samuel holds a BASc in Engineering Science from the University of Toronto and an MPhil from Cambridge University.
