=== Setting up the first gas chamber ===
Gas chamber in Hadamar Euthanasia Centre

According to Becker's testimony at the trial of Werner Heyde, the first medical director of Action T4,
<nowiki> </nowiki>in the first half January 1940, Becker drove to the Brandenburg 
institute, where buildings had been prepared specially for this purpose.
<nowiki> </nowiki>An area resembling a shower room with showerheads was laid out, about 3
<nowiki> </nowiki>meters by 5 meters in floor size, with a ceiling about three meters 
high.<sup>[4]</sup>

A pipe ran around the walls of the room, and in the pipe were small 
holes, out of which the carbon monoxide gas flowed. The gas bottles 
stood outside of the area and were already attached to the supply pipe. 
The assembly of the plant was accomplished by a mechanic of the 
SS-principal office Berlin. The gas-tight entrance door (''Gasdichttur'') included an observation port by which the behavior of the delinquents (''Delinquenten'') could be observed during the course of the gassing.<sup>[4]</sup>
