 A survivor of the Łódź ghetto, Arnold Mostowicz, noted in his memoir that Rumkowski gave a percentage of his people a chance to survive two years longer than the Jews of the Warsaw Ghetto, destroyed in the Uprising.However, as noted by Lucjan Dobroszycki, the ultimate decision on the future was not his to make.The ghettoization of Łódź was decided on September 8, 1939, by an order of "SS-Oberführer" Friedrich Uebelhoer.
