The letter, dated November 21, 1942, from the Reich Governor of the Reichsgau Wartheland Posen to Reichsführer-SS Heinrich Himmler, discusses the authorization granted “to subject those members of the Polish community who are proven to be afflicted with open and thus incurable pulmonary tuberculosis to special treatment”, which effectively meant execution. Despite thorough evaluation and planning, concerns regarding implementation were raised by Professor Dr. Blome, Deputy Head of the Main Office for Public Health of the NSDAP, in a letter dated November 18, 1942. Greiser seeks Himmler’s opinion on whether to inform the Führer about this stage of the process. However, he personally believes such consultation of Hitler may not be necessary, citing that previousy “regarding the Jews, he told me to proceed at my own discretion”.
