served as "a nineteenth-century bar code for human beings". In particular, critics point to the Order of the German Eagle medal that Watson received at the Berlin ICC meeting in 1937, as evidence that he was being honored for the help that IBM's German subsidiary Dehomag (Deutsche Hollerith-Maschinen Gesellschaft mbH) and its punch card machines provided the Nazi regime, particularly in the tabulation of census data (i.e. location of Jews). Another study argues that Watson believed, perhaps naively, that the medal was in recognition of his years of labor on behalf of global commerce and international peace. Because of his strong feelings about the issue, Watson wanted to return his German citation shortly after receiving it. When Secretary of State Hull advised him against that course of action, he gave up the idea until the spring of 1940. Then Hull refused advice, and Watson sent the medal back in June 1940. Dehomag's management disapproved of Watson's action and considered separating from IBM. This occurred when Germany declared war on the United States in December 1941, and the German shareholders took custody of the Dehomag operation. However, during World War II, IBM subsidiaries in occupied Europe never stopped delivery of punch cards to Dehomag, and documents uncovered show that senior executives at IBM world headquarters in New York took great pains to maintain legal authority over Dehomag's operations and assets through the personal intervention of IBM managers in neutral Switzerland, directed via personal communications and private letters. Dealings with the United States During this same period, IBM became more deeply involved in the war effort for the U.S., focusing on producing large quantities of data processing equipment for the military and experimenting with analog computers. Watson, Sr. also developed the "1% doctrine" for war profits which mandated that IBM receive no more than 1% profit from the sales of military equipment to U.S. Government. Watson was one of the few CEOs to develop such a policy. In 1941, Watson received the third highest salary and compensation package in the U.S., $517,221, on which he paid 69% in tax. Watson had a personal interest in the progress of the war. His eldest son, Thomas J. Watson Jr., joined the United States Army Air Corps and became a bomber pilot. He was soon hand-picked to become the assistant and personal pilot for General Follet Bradley, who was in charge of all Lend-Lease equipment
