Photograph taken in November 1942 during construction of the first nuclear reactor as the 19th layer of graphite was being added. The roughly spherical form of the structure is shown as is some of the supporting framework. Layer 18 (partially covered) contained uranium. Layers of graphite containing uranium metal and uranium oxide were spaced by sections of dead graphite to layer 57, one beyond critical or operating dimensions. The reactor was constructed beneath a portion of the west stands of the University of Chicago's Stagg Field, and was operated for the first time December 2, 1942.
