On January 6, 1942, Herman Krumey, the head of the Migration Central Office in Litzmannstadt, recorded the names of three SS men provided by the Migration Central Office to Sonderkommando Lange: SS-Obersturmführer Herbert Otto, SS-Hauptscharführer Fritz Ismer, and SS-Scharführer Karl Goede. The group was accompanied by the driver Grebe, whose first name remains unknown.

On July 16, 1941, authorities in the Reichsgau Wartheland convened to deliberate on what was euphemistically termed the “solution of the Jewish question.” Rolf-Heinz Höppner, head of the SD and Umwandererzentralstelle (Migration Center Office) in Posen, forwarded the discussed proposals to Adolf Eichmann, seeking his feedback. Höppner himself regarded the suggestions as “fantastic,” yet entirely viable.
