Gustave Mark Gilbert (September 30, 1911 – February 6, 1977) was an American psychologist best known for his writings containing observations of high-ranking Nazi leaders during the Nuremberg trials. In 1947 he published part of his diary, consisting of observations taken during interviews, interrogations, "eavesdropping" and conversations with German prisoners, under the title Nuremberg Diary. In 1945, after the end of the war, Gilbert was sent to Nuremberg, Germany, as a translator for the International Military Tribunal for the trials of the World War II German prisoners. Gilbert was appointed the prison psychologist of the German prisoners. During the process of the trials Gilbert became, after Douglas Kelley, the confidant of Hermann Göring, Joachim von Ribbentrop, Wilhelm Keitel, Hans Frank, Oswald Pohl, Otto Ohlendorf, Rudolf Höss, and Ernst Kaltenbrunner, among others. Gilbert also participated in the Nuremberg trials as the American Military Chief Psychologist and provided testimony attesting to the sanity of Rudolf Hess. His 1950 book The Psychology of Dictatorship was an attempt to profile the Nazi German dictator Adolf Hitler using as reference the testimonials of Hitler's closest generals and commanders. Gilbert's published work is still a subject of study in many universities and colleges, especially in the field of psychology. More
