(Historical note: This is also the day the Holocaust began. On this day Adolf Hitler issued the following order;

"Reichsleiter Bouhler und Dr. med. Brandt sind unter Verantwortung beauftragt, die Befugnisse namentlich zu bestimmender Ärzte so zu erweitern, dass nach menschlichen Ermessen unheilbar Kranken bei kritischter Beurteilung ihres Krankheitszustandes der Gnadentod gesährt werden kann."

[Reichsleiter Bouhler and Dr. Brandt are responsible for expanding the powers of physicians to be named who will, as best that can be humanly judged, give incurably ill people a merciful death if their condition is assessed as critical.]

More to the point, if someone is judged by an SS doctor to be incurable or mentally-ill, they can be euthanized against their will. The list of eligible people increased over time to even include malcontents. This was the order that began full scale testing of the most efficient ways to kill people in large numbers, and it started with Germans in mental institutions. The lessons learned here would be put to use in exterminating the Jews of Europe in the concentration camps.

Reichleiter Philipp Bouhler committed suicide on May 19, 1945 after being arrested by the U.S. Army, he surly would have been charged with crimes against humanity and executed had he lived. Dr. Karl Brandt was arrested and executed after the war.)
