The National Defense Research Committee (NDRC) was a United States government body created on June 27, 1940, to coordinate civilian scientific research for military purposes in the period before American entry into World War II. During the interwar period, relations between the military services and civilian scientists had largely broken down, and the existing advisory bodies lacked the funding and authority to bridge the gap. Vannevar Bush, an engineer and science administrator who chaired the committee, secured President Roosevelt's approval for the new agency in a meeting that lasted less than fifteen minutes. The NDRC introduced the use of government contracts with universities and industrial laboratories to conduct military research, an approach that kept scientists in their own institutions rather than conscripting them into government service. During its year of autonomous operation, the committee initiated programs in microwave radar, the proximity fuze, and early atomic weapons research, giving the United States almost eighteen months of military research and development before Pearl Harbor. On June 28, 1941, the NDRC was absorbed into the newly created Office of Scientific Research and Development (OSRD) as a subordinate advisory body, a role it held until its dissolution on January 20, 1947. The contract system the NDRC established became the template for postwar federal support of scientific research, shaping institutions including the Office of Naval Research, the Atomic Energy Commission, and the National Science Foundation.
Background During World War I, efforts to apply scientific expertise to military problems had been hampered by poor coordination between civilian researchers and the armed services. The National Academy of Sciences and its National Research Council, created in 1916 to advise government agencies on scientific questions, operated on the assumption that the military services would identify their own needs and then request assistance. The NRC's lack of independent funding and authority had left it unable to accomplish much for national defense before the United States entered the war in 1917. Relations between the Council and the military had never fully recovered, and by the interwar period the two services had retreated into largely separate research programs, neither making serious efforts to draw on the growing corps of civilian experts in fields such as electronics and nuclear physics.
By the late 1930s, Bush and several fellow science administrators believed that this model was inadequate for a war that would be shaped by rapidly advancing technology. Military officers, in their view, were not sufficiently familiar with recent scientific developments to know what might be possible; what was needed was an organization that could assess military requirements independently and propose solutions the services had not imagined. Bush drew on his experience as chairman of the National Advisory Committee for Aeronautics (NACA), which had served during the interwar period as a liaison between civilian science and the military in aviation research. He envisioned a similar intermediary body, but with broader scope and the authority to fund its own research through contracts. In informal discussions during 1939 and 1940, Bush, Karl T. Compton (president of MIT), James B. Conant (president of Harvard), and Frank B. Jewett (president of both the National Academy of Sciences and Bell Labs) agreed that the existing military laboratory system would not produce the novel weapons a modern war would demand. All four were distinguished scientists who had advanced to administrative positions, and all were Republicans who were wary of expanding government power, yet they were united in the conviction that civilian scientific leadership was essential for national defense. Bush in particular was no friend of the New Deal and a great admirer of Herbert Hoover, yet he was persuaded that effective mobilization required a new federal agency operating directly under presidential authority. As he later recalled: "I knew that you couldn't get anything done in that damn town unless you organized under the wing of the President."
Establishment On June 12, 1940, with the fall of France imminent, Bush secured a meeting with President Roosevelt through presidential advisor Harry Hopkins. Bush brought a single page describing the proposed agency. Roosevelt approved it in under fifteen minutes. The president signed a letter on June 15 authorizing the creation of the committee and appointing Bush as chairman. The letter specified that the NDRC was not intended to replace Army and Navy research but to "supplement this activity by extending the research base and enlisting the aid of the scientists." The NDRC was formally established on June 27, 1940, by an order of the Council of National Defense, a dormant World War I-era body of six Cabinet secretaries that was briefly revived to provide legal authority for the new committee. This mechanism allowed Bush to begin operations using presidential emergency funds without waiting for a congressional appropriation. Bush later acknowledged the unorthodox nature of the maneuver, recalling that the creation of the NDRC "was an end run, a grab by which a small company of scientists and engineers, acting outside established channels, got hold of the authority and money for the program of developing new weapons."
British scientific exchange
The NDRC received a major stimulus in September 1940 when the Tizard Mission, a British scientific delegation led by Sir Henry Tizard, arrived in Washington carrying detailed information about British advances in radar, fire control, underwater detection, and explosives. The British were authorized to share virtually any military secret in exchange for access to American research. Both sides found the other further advanced than expected, though as Baxter noted, in the early period of the exchange the British contributed more than they received.
