Abstract ' a Nazi and a psychiatrist. A fateful meeting on the eve of Nuremberg, Jack El Hai Douglas Kelly's name could have remained well-known in narrow medical circles, but history decided otherwise, throwing him into the epicenter of one of the most high-profile cases of the XX century. Kelly was appointed chief psychiatrist of the Nuremberg trials, where he established the sanity of 22 Nazi prisoners who were about to stand trial for atrocities committed by the Third Reich. The central theme of the book is a kind of Duel of minds, in which a psychiatrist came together with Hermann Goering and which, in the end, left an imprint on the life and death of each of them. Readers will also learn important details of the trial and biographies of the accused, as well as deep questions that Kelly faced during and after the diagnosis of Goering, Hess, Rosenberg, Ribbentrop, Keitel and others. What united the defendants? Did they all have mental disorders and innate tendencies to cruelty? And most importantly-does the "psychotype of a Nazi" really exist, or can everyone become a Nazi under certain conditions? Jack El-Hai is an American journalist and writer known for his work at the intersection of history, medicine, and psychology. The book " The Nazi and the psychiatrist. Fateful meeting on the eve of Nuremberg" is published in Ukrainian in "our format" and for the first time introduces the reader to a little-known page of post-war history. At the center of this work is the meeting of American military psychiatrist Douglas M. Kelly with Hermann Goering and other Nazi leaders who were awaiting trial in Nuremberg. The author reproduces in detail the process of interrogations, conversations and psychological experiments aimed at answering the difficult question – whether the main figures of the Third Reich were mentally ill, or their cruelty was a conscious choice. The book combines facts from court materials, Kelly's personal records, and the observations of his colleagues. There are no excessive artistic details here, but it is thanks to this that the reader sees events as they were. The atmosphere of the book is disturbing and at the same time intellectually rich. It raises questions that remain relevant today: what motivates a person to commit a crime against humanity, whether the authorities can turn ambitious and rational people into executioners, and how society should protect itself from the repetition of such tragedies.
