Olga Lengyel’s experiences as an inmate of Auschwitz-Birkenau fundamentally challenged her idea of a moral orderwith the enforced insight that perpetrators can be beautiful people who do evil things. Throughout her narrative, sheis rather focused on how she perceives perpetrators' behaviour in the camp and what meaning she can assign totheir moral conduct and outer appearance. Mainly in the English version of her 1946/47 book, she designed roles forthem to play in her attempt to recreate her own moral universe in the aftermath of World War II by integrating herexperience of Auschwitz-Birkenau into it. In her 1998 interview for the USC Shoah Foundation, however, she wasmainly concerned with her personal legacy. Olga Lengyel’s two main testimonies are examined within a synopsis ofaccounts by fellow survivors in an attempt to bring the study of multiple testimonies of survivors together withperpetrator research. What follows is an investigation of the functions of representations of perpetrators in Lengyel’sand others’ accounts, with special attention on the question of how survivors’ testimonies and media coverageshaped the public perception of Nazi perpetrators in the post-war years.
