Report by Topf & Söhne engineer Fritz Sander, dated September 14, 1942, on the new construction of incineration ovens for concentration camps. Sander points out the “high demand for cremation ovens” especially in Auschwitz”, where “they resort to using a large number of ovens or muffles and overloading the individual muffles with multiple corpses”. Furthermore, the practice that “multiple corpses must be packed into the muffle simultaneously…will likely cause damage to the relatively delicate muffle brickwork.”
Memo by Topf & Söhne engineer Kurt Prüfer regarding a phone call with the SS-Wirtschafts-Verwaltungshauptamt (SS Economic and Administrative Main Office) on September 8, 1942. Prüfer reports that the Auschwitz concentration camp is planning for cremation ovens with a total capacity to incinerate 2,650 corpses per day. However, he notes that “this number of muffles is still not sufficient; we are to deliver more ovens as quickly as possible.”
Report of SS-Untersturmführer Fritz Ertl, dated August 21, 1942 about a meeting with engineers Kurt Prüfer and Robert Köhler in Auschwitz from August 19 and 20, 1942. The report discusses the “installation of two 3-muffle ovens at the bathing installations for special actions”, an euphemism for the Bunker extermination sites.
The Franke-Gricksch Report was written by SS officer Alfred Franke-Gricksch following his visit to the Auschwitz concentration camp in May 1943. It describes in detail the processes involved in the mass extermination of Jews, including the use of gas chambers and crematoria.
