That is Ingrid Rimland, Ernst Zündel’s wife, talking about the showers in the ‘gas chambers’ in that clip at 1:10:20. The interviewer is Ernst, a Canadian German living in Canada who was persecuted and jailed several times for questioning the holocaust. His home was also torched for standing up for his beliefs. It was Ernst who brought Fred A. Leuchter Jr. (an American manufacturer of execution equipment) to Auschwitz-Birkenau in secret to carry out experiments to determine if there were actual gas extermination chambers. Fred determined it was impossible for there to be any gas extermination chambers and was outspoken about this which led to him also being persecuted and discredited.
