Wednesday, January 27, marks the 76th anniversary of the liberation of the Auschwitz-Birkenau concentration camp in Nazi Germany. In a world that is rife with discrimination and persecution, it is important that we remember testimonies like Leo‘s Journey and use its teachings to chart a path towards a more tolerant future.

While most of us know the Auschwitz-Birkenau concentration camp as the place where nearly 1.2 million prisoners – almost all of them Jewish – were exterminated, it had another equally dark and tragic secret. It was here that doctors performed horrific experiments on live prisoners, with a specific focus on twins. One of those was a 15-year-old Jewish boy named Leo Lowy. Leo went on to live a long and productive life, but the memories of what he and his twin sister, and countless others, had to endure at the hands of their captors stayed with him until his dying days. And before he passed away in 2002, Leo shared his story with his son Richard so what he and all the others endured would never be forgotten.
