Adolf Hitler devised the idea with the help of Nazi chief ideologist Alfred Rosenberg and Reichsführer-SS Heinrich Himmler, including the participation of SS-Obersturmbannführer Adolf Eichmann ("architect of the Holocaust"); as well as Heinrich Müller of the Gestapo, Hans Frank (Hitler's lawyer) and Arthur Seyss-Inquart of the Generalgouvernement administration. Gruppenführer Odilo Globočnik, the former Gauleiter of Vienna – appointed the SS and Police Leader of the new Lublin District – was put in charge of the reservation. During early implementation of the plan, the Nazis set up a system of ghettos for Jewish civilians to use them as the German workforce.
