Operation Paperclip: The Secret Intelligence Program that Brought Nazi Scientists to America

by Annie Jacobsen

One document, written by Albert Speer, described two meetings with himself, Ambros, and Hitler in June 1944 which not only confirmed the high position that Ambros held but that he was a war profiteer. “I (SPEER) reported to the Führer that Dr. AMBROS of I.G. FARBEN had developed a new process by which Buna of the same quality as natural rubber can be produced. Some time in the future no further imports of natural rubber will be required… the Führer has ordered a donation of one million marks” to Ambros, Speer wrote. A final piece of evidence shined a light on Farben’s long-term plans for its business venture at Auschwitz. In addition to its Buna factory, IG Farben planned to produce chemical weapons at the death camp. The company had “plans for further construction of CW plant at AUSCHWITZ… in February 1945,” Tilley wrote in his FIAT report.
