John Marshall’s Interview
After receiving his doctorate, John Marshall was hired to assist Leo Szilard with his experiments at Columbia. Afterwards, Marshall traveled to Chicago to work on Chicago Pile-1, and finally to Richland to work on the B Reactor at the Hanford site. Marshall was on duty when the reactor shut down due to xenon poisoning. He discusses his experience working for Szilard and alongside Fermi, as well as the steps taken when the B Reactor shut down on his watch.
