During the war, Deutsche Bank incorporated other banks that fell into German hands during the occupation of Eastern Europe. Deutsche provided banking facilities for theGestapo and loaned the funds used to build the Auschwitz camp and the nearby IG Farben facilities. Deutsche Bank revealed its involvement in Auschwitz in February 1999.[20] In December 1999 Deutsche, along with other major German companies, contributed to a $5.2 billion compensation fund following lawsuits brought by Holocaust survivors.
FYI: My friend a survivior got zip from Deutsche Bank for his stay in Auschwitz!
IG Farben was the most powerful German corporate cartel in the first half of the 20th century and the single largest profiteer from the Second World War. IG (Interessengemeinschaft) stands for "Association of Common Interests": IG Farben included BASF, Bayer, Hoechst, and other German chemical and pharmaceutical companies.
As documents show, IG Farben was intimately involved with the human experimental atrocities committed by Mengele at Auschwitz.
