Trinity Test Site, Oppenheimer Oversees Assembly, 1945

Oppenheimer oversees final assembly of Gadget. Assembly of the nuclear capsule began on July 13 at the McDonald Ranch House, where the master bedroom had been turned into a clean room. The polonium-beryllium Urchin initiator was assembled, and Louis Slotin placed it inside the two hemispheres of the plutonium core. Cyril Smith then placed the core in the uranium tamper plug. Air gaps were filled with 0.5-mil (0.013 mm) gold foil, and the two halves of the plug were held together with uranium washers and screws which fit smoothly into the domed ends of the plug. The completed capsule was then driven to the base of the tower. Julius Robert Oppenheimer (April 22, 1904 - February 18, 1967) was an American theoretical physicist. Along with Enrico Fermi, he is often called the father of the atomic bomb for his role in the Manhattan Project, the WWII project that developed the first nuclear weapons. The first atomic bomb was detonated on July 16, 1945, in the Trinity test in New Mexico; Oppenheimer remarked that it brought to mind words from the Bhagavad Gita: Now, I am become Death, the destroyer of worlds
