We spent the day in the Konrad-Adenauer-Stiftung, at 30 Tiergartenstrasse. We listened to several presentations, and no mention of what lay down the road at number 4. Now it is the Berlin Philharmonic, and the original building long since gone in the bombings and Soviet assault on Berlin. But what was once there was the origins of the Holocaust. Action T4 involved scientists explaining why some humans were unworthy of life and how, scientifically, economically, and politically, euthenizing them, giving them a "good death," was not only acceptable but desireable. This was the first step to acceptance of Die Endloesung von die Judenfrage in Europa, the final solution of the Jewish question in Europe. Moreover, it was in Action T4 that the Nazi sensitivity to criticism is shown - when protests broke out in Berlin, the project was shut down,,,in Berlin. Instead, it moved to the other sites, such as Grafeneck and Sonnenstein. It was also where the Nazis developed their technical expertise in mass murder and began the use of gas. In fact, it was the T4 experts who were sent east to set up the death camps. And yet most often no mention is made of this program in Holocaust education. Omitting it is rather like trying to teach about World War Two without ever mentioning World War One.
