1. The T4 Program
The German government established, under the Reich Chancellery, the Euthanasie Programme under the direction of Philip Bouhler and Dr. Karl Brandt. The headquarters of the operation were at Tiergartenstrasse 4, Berlin and the code name for the program was derived from that address—T-4.

Background
Between December 1939 and August 1941, about 50,000 to 60,000 Germans—children and adults—were secretly killed by lethal injections or in gassing installations designed to look like shower stalls. It was a foretaste of Auschwitz. The victims were taken from the medical institution and put to death.... (Never to Forget, New York: HarperCollins, 1976:131.)

3. "The first mass-murder by the Nazis was organized from 1940 onwards on this spot, the Tiergartenstraße 4 and named "Aktion T4" after this address. From 1939 to 1945 almost 200,000 helpless people were killed. Their lives were termed "unworthy of living", their murder called "euthanasia". They died in the gas chambers of Grafeneck, Brandenburg, Hartheim, Pirna, Bernburg and Hadamar, they died by execution squad, by planned hunger and poisoning.

"This person suffering from hereditary defects costs the people 60,000 Reichmarks during his lifetime. People, that is your money. Read 'New People'."

7. Nazi propaganda in the form of posters, news-reels and cinema films portrayed disabled people as "useless eaters" and people who had "lives unworthy of living". The propaganda stressed the high cost of supporting disabled people, and suggested that there was something unhealthy or even unnatural about society paying for this. One famous Nazi propaganda film, Ich Klage An (I Accuse), told the story of a doctor who killed his disabled wife. The film put forward an argument for "mercy killings". Other propaganda, including poster campaigns, portrayed disabled people as freaks.

13. The roots of the Nazi gas chambers are to be found in the testimony of Richard v. Hegener, employee of the "Chancellery of the Führer": Originally one has taken into consideration to kill the single incurable persons ... by injections or overdosed sleeping pills. But this consideration ... has been called impracticable from the technical point of view ..., by the majority of the consulted doctors. Therefore it was proposed ... to kill the persons being eligible simultaneously in a bigger crowd somehow. After many consultations ... hearing the chemist of the Reichskriminalpolizeiamt too, one decided to install a room in a number of conveniently located sanatoriums. The room should be filled with carbon monoxide gas then ...
