It seems that my mother is wrong to say that it would be difficult to attribute knowledge of the real use of Zyklon B gas to the manufacturers of this pesticide. The historical record shows otherwise.
Anthony Cox has on his blog today pointed out that Bruno Tesch and Karl Weinbacher were tried and executed by the British military authorities in Hamburg. The chemists knew full well what was going on, and a report of their trial is available as a PDF file.
I pointed this out to Katharine, and advised her to put together a short addendum to her essay. This she has just done. It was only recently that Katharine started reading around this subject.
Katharine’s oversight aside, her description of the camps at Majdanek and Sobibor is particularly powerful. Stacks of shoes you can touch, and “a few bits of uncrushed bones”? Maybe this is a pilgrimage we should all make once in our lives.
