United States. Office of Scientific Research and Development. 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. Its working arm was superseded by the Office of Scientific Research and Development in 1941, but it remained as an influential advisory and consulting agency until it was terminated in 1947.
