Hitler ließ sich am 7. Oktober 1942 persönlich von Odilo Globocnik über die Judenmorde in vier Vernichtungslagern unterrichten
Without providing a specific source, we are told that Hitler was personally informed by Odilo Globocnik about the murder of Jews in "four" death camps on Oct. 7, 1942.
I cannot find anything about it on CODOH.
This website https://phdn.org/archives/holocaust-history.org/operation-reinhard/ contains the only reference I can find quickly, online, to this meeting:
Globocnik drew on personnel who had been involved in the T4 euthanasia killings, as well as other SS staff, to carry out the detailed organization. Chief among these were Sturmbannführer [Major] Hermann Höfle, who was in charge of administration and Sturmbannführer Christian Wirth, who was in charge of the construction of the camps and was later their inspector.
That Hitler was well aware of this is demonstrated by the fact that Globocnik was received by Himmler at the Reich Chancellery in 1942, likely in October. Himmler never received subordinates at the Reich Chancellery, but rather at his own headquarters in the Prinz Albrechtstrasse. Himmler's notes for a discussion with Hitler on October 7, 1942, read: "Conditions Gen. Gouv. Globus" [Conditions Generalgouvernement Globus]. "Globus" was Globocnik's nickname. And it is around this time that Globocnik visited the Reich Chancellery. It is most likely that he briefed Himmler, who then went down the hall to brief Hitler.
What is the revisionist understanding of this event? Did Globocnik meet Hitler or just Himmler? Why would Hitler wish to discuss the conditions of the Generalgouvernement with Globocnik? After the stormy sermons of bishops turned public sentiment against T4, is there any further record of Hitler's personal or public thoughts on T4's continuation beyond its legal establishment? Himmler's "Globus" seems to be singled out for often opprobrium by the mainstream narrative as a particularly vile character, so I can never tell what is real or false.
