Architects of Death: The Family Who Engineered the Holocaust

Topf and Sons designed and built the crematoria at the concentration camps at Auschwitz-Birkenau, Buchenwald, Belzec, Dachau, Mauthausen and Gusen. At its height sixty-six Topf triple muffle ovens were in operation - forty-six of which were at Auschwitz. In five years the gas chambers and crematoria of Auschwitz had been the engine of the holocaust, facilitating the murder and incineration of more than one million people, most of them Jews.
