With the death of Whitney Harris, the world has lost a living link to a key event in post-World War II history. Harris was the last surviving courtroom prosecutor from the first Nuremberg trial, which convicted 18 top Nazis and established an undeniable record of the Holocaust. As one of the youngest members of the American legal staff, Harris prosecuted a high-ranking SS member and got critical testimony from the commandant of Auschwitz. This experience made Harris a leading advocate for international law and the modern war crimes tribunals that are Nuremberg's legacy. Harris died in St. Louis on Wednesday at age 97.
