S-1 Executive Committee

The S-1 Executive Committee laid the groundwork for the Manhattan Project by initiating and coordinating the early research efforts in the United States, and liaising with the Tube Alloys Project in Britain. It evolved in June 1942, alongside the S-1 Section of the Office of Scientific Research and Development (OSRD), from the Uranium Committee of the National Defense Research Committee (NDRC), which had itself evolved from the Advisory Committee on Uranium when the OSRD absorbed the NDRC in June 1941.
