Throughout his 85 years, Thomas Buergenthal has experienced justice from all angles. He has been deprived of it, reclaimed it, fought for it for others and worked to strengthen it worldwide. He is one of the youngest survivors of the Auschwitz camp, freed at age 11. Even now, Buergenthal has yet to give up hope for a just world, and he continues to make strides toward one through his work in the field of international law, detailed in the new documentary Peace through Justice: Past, Present, and Future. "I seem to have been born with an optimism that my father had," Buergenthal says during an interview at his home office in Washington, DC. "I think cynicism makes you inactive."
