Q. And you think that Hadamar was the last one that was set up?
A. I am quite certain that Hadamar was the last one.
Q. Now, of what materials were these gas chambers built? Were they movable gas chambers, very much like the low-pressure chambers that Professor Dr. Ruff talked about, or were they something that was built permanently into the camp or installation?
A. No special gas chamber was built. A room suitable in the hospital was used, a room of necessity attached to the reception ward and to the room where the insane persons were kept. This room was made into a gas chamber. It was sealed, given special doors and windows, and then a few meters of gas piping were laid, or some kind of piping with holes in it. Outside this room there was a container, a compressed gas container with the necessary apparatus, that is a pressure gauge, etc.
Q. Now what department had the responsibility for constructing or building these gas chambers, what department of the Party or of the government?
A. No office of the Party. I don’t understand the question.
Q. Somebody had to build these chambers. Who gave the orders and who had the responsibility of building them, was that your department?
A. I assume the orders were given by the head of the institution, but I don’t know who actually did give the orders.
Q. In other words, were these chambers not built according to some specifications, plans and specifications?
A. I can’t imagine that, every chamber was different. I saw several of them.
