This link will take you to the website of the U.S. Holocaust Memorial Museum where there are five audio-only interviews with Rudolf Vrba. Perhaps most remarkable is Vrba’s relative equanimity as he consents to matter-of-factly respond to a string of naive questions for an hour.

Due the lack of visual content, this significant material will doubtless be under-regarded, particularly because Vrba’s accent makes his English hard to understand upon first hearing, or even second hearing. Nonetheless, any serious Vrba scholar is well-advised to listen and discover significant pieces of information, informally offered, that cannot be otherwise gleaning by reading his memoir.

Vrba describes his experiences at Majdanek, where he saw children killed, women clubbed, and bones broken; spending 14 days in the camp then volunteering in June 1942 with 400 other men to go to Auschwitz; the selection process in the camp; his friends from the Sonderkommando unit who were killed; and how each day was a fight for the possibility of living another day; the separation of the Sonderkommandos from the general prisoners; the attitudes of the Sonderkommandos while they were working; hearing in January 1944 that a large extermination action was being planned, thereby increasing his desire to escape; escaping with his friend code-named Vecla Margovich (Alfred Wetzler); being questioned by the Jewish Council in Bratislava, who did not believe at first what he said about Auschwitz; receiving help from the Communist group in Trnava; his return to Bratislava; living with the partisans for about two months (likely in the fall of 1944); and his thoughts on the war crime trials for Auschwitz guards.
