Walt Simon, a chemist, was Hanford’s first Operations Manager. Before joining the Manhattan Project, he was plant manager at Wabash River Ordnance Works, a DuPont plant near Terre Haute, Indiana. He moved to Richland in the summer of 1944. He watched the B Reactor go critical, and then shut down due to the Xenon poisoning.
