22461565	National Defense Research Committee National Defense Research Committee The National Defense Research Committee (NDRC) was an organization created to coordinate, supervise, and conduct scientific research on the problems underlying the development, production, and use of mechanisms and devices of warfare" in the United States from June 27, 1940, until June 28, 1941. Most of its work was done with the strictest secrecy, and it began research of what would become some of the most important technology during World War II, including radar and the atomic bomb. It was superseded by the Office of Scientific Research and Development in 1941, and reduced to merely an  advisory organization until it was eventually terminated during 1947. Organization. The NDRC was created as part of the Council of National Defense, which had been created during 1916 to coordinate industry and resources for national security purposes, by an order of President Franklin Delano Roosevelt on June 27, 1940. Vannevar Bush, the director of the Carnegie Institution, had pressed for the creation of the NDRC because he had experienced during World War I the lack of cooperation between civilian scientists and the military. Bush managed to get a meeting with the President on June 12, 1940, and took a single  sheet of paper describing the proposed agency. Roosevelt approved it in ten minutes. Government officials then complained that Bush was attempting to increase his authority and to bypass them—which he later admitted he was: In his June 15 letter which appointed Bush to the head of the committee, Roosevelt outlined that the NDRC was not meant to replace the research work done by the Army and Navy in their own laboratories or through industry contracts, but rather to "supplement this activity by extending the research base and enlisting the aid of the scientists who can effectively contribute to the  more rapid improvement of important devices, and by study determine where new effort on new instrumentalities may be usefully employed." (Quoted in Stewart 1948, p. 8). The NDRC was managed by eight members, one of which was the chairman and two of which were appointed automatically by virtue of their positions as President of the National Academy of Sciences and the Commissioner of Patents. One member was appointed by the Secretary of War and another by the Secretary of the Navy; the other four members were appointed without reference to other offices. The original eight members of the NDRC were : Vannevar Bush, President of the Carnegie Institution (Chairman); Rear Admiral Harold G. Bowen, Sr.; Conway P. Coe, Commissioner of Patents; Karl Compton, President of MIT; James B. Conant, President of Harvard University; Frank B. Jewett, President of the National Academy of Sciences and President of Bell Telephone Laboratories; Brigadier General George V. Strong; and Richard C. Tolman, Professor of Physical Chemistry and Mathematical Physics at California Institute of Technology. Strong was succeeded by Brigadier General R.C. Moore on January 17, 1941. During its first meeting on July 2, the NDRC elected Tolman as its Vice-Chairman and appointed Irvin Stewart  as its Secretary. The NDRC members met approximately once a month until September 1942, after which it met either weekly or bi-weekly until the end of the war with Germany, after which it met irregularly. NDRC research. Under the chairmanship of Bush the NDRC created new laboratories, including the Radiation Laboratory at the Massachusetts Institute of Technology, which aided the development of radar, and the Underwater Sound Laboratory at New London, Connecticut, which developed sonar. The former grew to be the largest single activity of the NDRC. In the year of its autonomous existence, the NDRC received approximately $ 6,500,000 (out of a requested $10,000,000) for research. The NDRC's most important project eventually became the Manhattan Project—the full-scale project to produce nuclear weapons by the United States. An Advisory Committee on Uranium had been established to consider the feasibility of an atomic bomb as part of the National Bureau of Standards during 1939 as the result of the Einstein–Szilárd letter, but had not made significant progress. It was instructed in Roosevelt's June 15 letter to report to the NDRC and Bush, establishing the chain of command which would later result in the full -scale bomb project. During June 1940 Bush reorganized the Uranium Committee into a scientific body and eliminated military membership. No longer beholden to the military for funds, the NDRC had greater access to money for nuclear research. However, there was little impetus until the British MAUD Committee's findings were presented in 1941. Creation of the OSRD. The increasing hostilities in Europe cause a desire to create a new organization which would supersede the NDRC and remedy some of the problems the NDRC was facing, in particular in converting scientific research into usable military technology ("development"), increased liaison between the  different parts of military and civilian research in different government agencies, and creating a system for funding military medicine. At Bush's insistence Roosevelt issued Executive Order No. 8807 on June 28, 1941, which established the Office of Scientific Research and Development. The NDRC technically still existed after the creation of the OSRD but its authority had been reduced from being able to actually fund research to becoming simply an advisory body to the OSRD. The NDRC ceased to exist officially after its last meeting on January 20, 1947. When it became the NDRC of the OSRD, the committee membership  and structure was re-organized. The NDRC of the OSRD membership consisted of Conant (Chairman), Tolman (Vice-Chairman), Adams, Compton, and Jewett, along with the Commission of Patents (Coe until September 1945, and then Casper W. Ooms), and the representatives of the Army and Navy (which changed periodically). The Committee on Uranium was reorganized as the S-1 Section and it stopped being part of NDRC jurisdiction during December 1941. Select NDRC projects. The NDRC funded research into hundreds of different projects at many different educational and industrial sites around the country. Some of the ones it is best remembered for  include: NDRC research organization. The NDRC's research organization changed constantly during its single year of autonomous existence. During early June 1941, shortly before it was superseded by the OSRD, its organization was as follows: The Committee on Uranium, chaired by Lyman Briggs, reported directly to the Chairman of the NDRC and as such does not appear in the chart above. Following the reorganization of the NDRC in December 1942, it had the following divisions: National Defense Research Committee The National Defense Research Committee (NDRC) was an organization created "to coordinate, supervise, and conduct scientific research on the problems underlying
