The Bush Crime Family TreeGeorge Walker, GW's great-grandfather, set up the takeover of the Hamburg-America Line, a cover for I.G. Farben's Nazi espionage unit in the United States. In Germany, I.G. Farben was most famous for putting the gas in gas chambers; it was the producer of Zyklon B and other gasses used on victims of the Holocaust. The Bush family was not unaware of the nature of their investment partners. They hired Allen Dulles, the future head of the CIA, to hide the funds they were making from Nazi investments and the funds they were sending to Nazi Germany, rather than divest. It was only in 1942, when the government seized Union Banking Company assets under the Trading With The Enemy Act, that George Walker and Prescott Bush stopped pumping money into Hitler's regime. (1)
