The extraordinary story of how two boys survived humanity’s darkest hour – and then found each other again half a century later. Kalman & Leopold is the harrowing firsthand account – narrated to the latter’s son Richard K. Lowy, who joins us here – of a pair of children spared from the Auschwitz gas chambers, only to be subjected to Mengele’s brutal experiments and forced to serve the hospital camp’s sadistic guards. Amidst the casual barbarity, their bond became their salvation—a brotherhood of wit and courage. Separated at liberation, Kalman then began a 56-year search for his protector.
