still a powerful influence. While Zimmerman has written that the Navyremoved many of their restrictions concerning the sharing of U.S. technologyby 4 September 1940, a 16 September 1940 memorandum from DNI Andersonto the head of the U.S. <strong>National</strong> Defense Research Council (NDRC), Dr. VannevarBush, made it clear that the NDRC was not to discuss any Navy technologieswith the British without Navy Department personnel present, that theNDRC must not discuss anything on the Navy’s list of topics prohibited for discussion,and that there must be nothing discussed about capabilities in development.232 Bush replied two days later, stating the NDRC would respect theNavy’s policy but was hopeful it would change “since all of the work of theCommittee has to do with development, and since “I [Bush] believe that thediscussions on such matters are likely to be of particular benefit.” 233By the end of September, the rest of Tizard’s team had arrived in the U.S. andsometime around 27 September, Tizard presented his American hosts with a “resonantcavity magnetron,” the key component for constructing a microwave radar, apiece of technology the U.S. was still months, if not years, away from developingindependently. 234 Both Zimmerman and Leutze contend that this magnanimous giftand the free and open exchange of other information the British provided during themonth proceeding its delivery, completely changed the attitude of the Navy and WarDepartments with regard to sharing of technical information. 235 The archival dataconfirm this assessment. On 28 September 1940, Secretary of the Navy Frank Knoxissued a letter concerning the Tizard Mission to all the bureaus of the Navy staff. Inthat letter, he cancelled all restrictions on the provision of technical information toGreat Britain with the exception of the Norden bombsight and the antenna mine,which were to remain secret. Knox’s reasoning, much like Kirk’s, was that the Britishshould be given “drawings, specifications, performance data and any otherdetailed information” concerning U.S. technologies because “advantages...willaccrue to [the United States] in the matter of procurement and combat tests.” 236 ByOctober, even the pessimistic RADM Bowen was won over by the liberality of the232Walter S.

The NDRC was formed byRoosevelt earlier in 1940. A civilian organization formed at Roosevelt’s direction, its charter wassimilar to today’s Defense Advanced Research Projects Agency (DARPA). Although the NDRCwas not supposed to duplicate research being done by the military service labs, there was distrustbetween the labs and the NDRC, as indicated by Anderson’s concerns that members of the NDRCwere meeting independently with members of the Tizard mission.233 Dr. Vannevar Bush, Letter to Rear Admiral Walter S.
