These are small gas-chambers, designed to exterminate vermin,
mainly lice, a population that thrived in Birkenau. There were many of
these chambers, operated by prisoners, in the Sauna. They were placed in
the wall, with a room on either side; one side was dirty, the other, clean.
Ex-prisoner Manya Buki, worked here gassing vermin in the clothes of new
arrivals. "Vermin" was also a term used by Nazi propagandists
to describe the Jews. It is easier to kill people seen as insects. This
term, "vermin", used by Nazi theoreticians, propagandists and
camp officials to consciously desensitize those ordered to commit murder.
Mrs. Buki also did this to prisoner's uniforms, while they waited outside,
sometimes all day in freezing weather. The irony of it: a Jewish women
using Zyclon B, the same gas used to exterminate people, gassing actual
"vermin" in Birkenau.
