Jean Améry, born Hanns Chaim Mayer, was an Austrian-born essayist whose work was often informed by his experiences during World War II. His most celebrated work, At the Mind's Limits: Contemplations by a Survivor on Auschwitz and Its Realities (1966), suggests that torture was "the essence" of the Third Reich. Other notable works included On Aging (1968) and On Suicide: A Discourse on Voluntary Death (1976). He first adopted the pseudonym Jean Améry in 1955. Améry killed himself in 1978.
