up with the idea for his analog device. He enlisted his colleague L.D.P. King to build the instrument, which was later given the fitting name FERMIAC. The device was used for approximately two years. The Fermiac is on display in the Bradbury Science Museum in Los Alamos. In 2015, the Museo Storico della Fisica e Centro Studi e Ricerche “Enrico Fermi” created a replica of the device. A presentation of the device by Coccetti et al. is available as PDF.
