After more than five decades and the appearance of innumerable books and monographs on its every facet, is there anything radically new remaining to be uncovered about the Holocaust? According to Edwin Black there is. His IBM and the Holocaust drops the bombshell of a revelation that the Nazis, in pursuing the destruction of European Jewry, were assisted in decisive ways by a leading American corporation.
I.B.M., Black reports, knowingly provided the Third Reich with the technology to identify German Jews in the period 1933-1939. After World War II broke out in Europe, Hitler's plan to exterminate the Jews became a mission the company pursued with chilling success. Drawing on documents from archives in the United States and across Europe, Black tells the astonishing story of a corporation and a corporate leader, Thomas J. Watson, eagerly conniving with the Nazis as they carried out their murderous program.
