Felenbaum-Weiss, Hella
Hella Felenbaum-Weiss was an inmate of the Sobibór Camp. In a deposition probably recorded in 1946, she claimed that inmates were gassed using chlorine inside the train during transit on the way to Sobibór. This claim is rejected as false by the orthodoxy, who insists that inmates were gassed only after their arrival at the camp in stationary gas chambers using engine-exhaust gas.
