Large blueprint, yellowed paper, purple-brown print of measured structural plans. Square in bottom right corner titled "DEGESCH, Frankfurt a. Main" and stamped with"geheim in red ink.
Information Provided by Michael D. Bulmash: Degesch held the patent for Zyklon-B, initially developed for use as a pesticide, but used in gas chambers in major extermination centers including Auschwitz- Birkenau and Majdanek. Bruno Tesch, instrumental in developing the canisters to package the hydrogen cyanide- based formula, sold the German army and SS on using Zyklon-B to murder humans. This blueprint seems to depict a gassing chamber circulation system for wither delousing or for extermination of humans, with roof vents for dropping Zyklon-B pellets into the gas chamber room, and ventilation valves for expelling the gas after being administered. Sonderkommandos, prisoners themselves. Conducted the work of dragging the dead bodies from the gas chambers to nearby incinerators.
This blueprint, red-stamped “Geheim” (“Secret”) is dated around the time that Auschwitz-Birkenau was a fully functional extermination facility.
