From a Wall Street Journal review by Diane Cole of the book by Peter Longerich titled “Wannsee: The Road to the Final Solution”:

A single meeting can distill the essence of evil. Eighty years ago, on Jan. 20, 1942, Reinhard Heydrich, the head of the SS intelligence service and security police, presided over a high-level meeting with 14 Nazi colleagues at the elegant Wannsee villa near Berlin. The agenda: to discuss “the final solution of the Jewish question in Europe.” At the gathering’s conclusion, the event’s invitation noted, breakfast would be served.
