Well, IBM is a German originated company, they leased their products/tech to their german branch, Dehomag, who were instrumental in segragating the Jewish population from the rest of germans, due to IBM's unrivalled census punch card system, and then each and every card passed through the main offices of IBM at one stage where they were sorted and sent to their German posts. This clearly showed the exact nature of the regime in "eradicating" the Jewish population and as such represents a key focus within establishing the chain of command within Auschwitz
hehe sorry bout that, theres a book IBM and the holocaust if you want to read more, cant remember the author though atm
sorry
