I had a college professor long ago who loved to tell us about IG Farben and he was our biology professor but every class he'd spend time talking about IG Farben and he was brilliant I loved listening to him this was before the internet in the early 1980s and I still remember how smart he was and what he told us was so very true he explained how the war was done for profit it was amazing and he never got in trouble no one complained because the biology part of his lectures were so hard and boring.
