Patricia Posner is a British-born writer who has collaborated with her husband, the author Gerald Posner, on twelve non-fiction books, including Mengele: The Complete Story — a biography of Dr. Josef Mengele; Hitler's Children — a 1991 collection of interviews with the children of Nazi perpetrators; and most recently, God's Bankers — a financial history of the Roman Catholic Church. Her work has appeared, among other places, in the Miami Herald, The Daily Beastand Salon. She lives in Miami Beach. Her book, The Pharmacist of Auschwitz, is the little known story of Victor Capesius, a Bayer pharmaceutical salesman from Romania who, at the age of 35, joined the Nazi SS in 1943 and quickly became the chief pharmacist at the largest death camp, Auschwitz. Based in part on previously classified documents, Patricia Posner exposes Capesius's reign of terror at the camp, his escape from justice, fueled in part by his theft of gold ripped from the mouths of corpses, and how a handful of courageous survivors and a single brave prosecutor finally brought him to trial for murder twenty years after the end of the war.
