The Manhattan Project was a research and development project that produced the first nuclear weapons during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corp of Engineers; physicist J. Robert Oppenheimer was the director of the Los Alamos, NM National Laboratory that designed the actual bombs. These statues of Oppenheimer & Groves stand outside the Fuller Lodge, in Los Alamos, NM just around the corner from the National Lab. The Fuller Lodge housed many of the visiting scientists and consultants who also participated in the Manhattan Project research.
