It wasn't Farben by any chance was it? IG Farber was a major user of Jewish slave labour from Auswitch during the war.
It was Thyssen. Lot's of creepy things found when you turn over that rock. Apparently Bush's grandpa made his fortune from the Nazi's with Thyssen involvment. You need a strong stomach when you start researching companies like Thyssen, Krupp, Bayer, Nestle' [that's right] etc. and let's not forget Ford, Standard Oil and IBM.
