The data was collated on IBM punch card machines, a lovely company if you like holocausts.
replyIt does rise an interesting question, how much can you blame a company for the crimes of it's customers?
replyIG Farben was deeply involved with supporting all that unpleasant business, much more so than IBM.
replyIBM was extremely involved in purposefully collaborating with the reich to run censuses to identify Jewish populations, not to mention running actual prisoner inventory at various concentration camps. They specifically made overseas subsidiaries to shield this activities from US sanctions at the time.
replyRight, which is still few steps removed from the actual genocide. IG Farben was a direct participant, to the point where a lot of their execs were tried and convicted at Nuremberg.
replyBut I'm not sure the focus on corporations is all that interesting here. The Allies eventually let most of the senior Nazi leadership walk free, and few in Germany faced any lasting consequences for what they did during the war (even IG Farben execs were released before too long). I think the idea was that they needed to govern the nation they have, and mass-imprisonment wasn't a viable strategy. It worked out in a pragmatic sense, but it was hardly justice for the millions of civilians exterminated by the regime.
