About Michal Urbach, Dr
Dr Michal Urbach was head of the hospital, a neurologist, and among the Jews who reached Lodz from Brzeziny a few months earlier. He was the camp pharmacist.
His only child, a boy of five had been taken away with the other children under ten, sent to Chelmno and gassed on 18 May 1942. All the children from Brzeziny, like those of Pabianice, had been sent to Chelmno and gassed.
