Podchlebnik, Salomon
Salomon Podchlebnik was an inmate of the Sobibór Camp. In a concise deposition of 6 December 1945, he claimed that inmates at Sobibór were killed with an unspecified gas in one gas chamber, resulting in half a million victims. The orthodoxy insists, however, that there were several gas chambers, and that only half as many victims or even less died in the camp.
(See the entry on Sobibór for more details, as well as Mattogno 2021e, p. 77.)
