Gisella Perl (10 December 1907 – 16 December 1988) was a Hungarian Jewish gynecologist deported to Auschwitz concentration camp in 1944, where she helped hundreds of women, serving as an inmate gynecologist for them. She worked without the bare necessities for practicing medicine. Perl survived the Holocaust, emigrated to New York, and was one of the first women to publicize the Holocaust experience in English, in her 1948 memoir I Was a Doctor in Auschwitz.
In June 1948, Gisella Perl published the story of her incarceration at Auschwitz, detailing the horrors she encountered as an inmate gynecologist. The book included Perl's description of operations on young women's breasts without anesthetics, using a knife as her only instrument. She described Irma Grese, a 19 year old Aufseherin or warden from Auschwitz who observed the procedures and derived pleasure from their suffering. She wrote that Grese's “face [was] clear and angelic and her blue eyes the gayest, the most innocent eyes one can imagine.” Her words helped paint a picture of Grese when the notorious guard was put on trial and subsequently executed.
