If you read Martin Amis’s The Zone of Interest, or saw the 2023 movie based on the book, you know about the pitiless balancing act of Rudolf Hoess, the commandant at Auschwitz. He lived in a dream villa bordering the camp, a mini utopia created for his family’s happiness, and took an underground tunnel into the camp to do his day job—the genocide of the Jewish people. That house, 88 Legionów Street, is now ARCHER at House 88—the Auschwitz Research Center on Hate, Extremism and Radicalization. The center is dedicated to confronting “not just the consequences of extremism but the quiet, everyday mechanisms that allow people to rationalize, normalize, and ultimately encourage it.” ARCHER’s new exhibition is a perfect example of such compartmentalization and moral camouflage. Dr. Günther Niethammer, a Waffen-SS guard at Auschwitz, was also a leading ornithologist. Can a man who loves and studies birds be the same man who keeps mass murder running like clockwork? We know the answer. The exhibition includes bird specimens, new documents, and archival footage. —Laura Jacobs
