IBM also maintains, in a February statement to which it refers most questions on the matter, that the Nazis took control of its German unit before and throughout the war, and that the company "does not have much information about this period or the operations of Dehomag." Black vehemently disputes both claims.
IBM also defended Chairman Thomas Watson for his dealings with Hitler and his regime.
"As chairman of a major international company and a strong supporter of international trade, he met and corresponded with senior government officials from many, many countries, Hitler and Germany among them, in the 1930s," Makovich wrote. "As far as we know, the nature of the contacts between IBM executives and German government officials during the 1930s were similar to those with other government officials in other countries and consistent with IBM practices in the various countries in which the company did business during that era."
