Editing Argonne National Laboratory (section)

===Origins===
Argonne began in 1942 as the [[Metallurgical Laboratory]], part of the [[Manhattan Project]] at the [[University of Chicago]]. The Met Lab built [[Chicago Pile-1]], the world's first [[nuclear reactor]], under the stands of the University of Chicago sports stadium. In 1943, CP-1 was reconstructed as CP-2, in the [[Palos Forest Preserves|Argonne Forest]], a forest preserve location outside Chicago.  The laboratory facilities built here became known as [[Site A]].

On July 1, 1946, Site A of the "Metallurgical Laboratory" was formally re-chartered as Argonne National Laboratory for "cooperative research in nucleonics." At the request of the [[United States Atomic Energy Commission|U.S. Atomic Energy Commission]], it began developing nuclear reactors for the nation's peaceful nuclear energy program. In the late 1940s and early 1950s, the laboratory moved west to a larger location in unincorporated [[DuPage County, Illinois|DuPage County]] and established a remote location in [[Idaho]], called "Argonne-West," to conduct further nuclear research.
