First Nuclear Explosion's Echo Still Felt Today on Chicago Squash Court
A two part series recounts the gathering of scientists and workers in Chicago as the metal troughs and graphite blocks were secretly assembled to build the first nuclear pile. Key figures include Gus Knuth Bob Nobles Herbert Anderson Samuel Allison Norman Hillberry Leona Woods and Leo Sayvetz. The story traces university decisions Chancellor Hutchins and Dean Filbey faced about risking a city and the war effort and how secrecy shaped the project. The account highlights the purity challenges with graphite and uranium and the rush to produce cleaner materials from Westinghouse Eldorado Mallinckrodt and others to enable a working chain reaction.

Fermi Sees First Self Sustaining Chain Reaction at CP1
Historic account recalls Enrico Fermi and a diverse crew from master carpenters to PhDs building CP1 the Chicago pile. They measured and adjusted the uranium graphite stack through a day of precise steps ending with a self sustaining chain reaction. Safety drills resignations and the emotional hush as the pile reached criticality are described alongside personal recollections of Nobles Kubitschek Anderson and Leona Marshall.
