Enrico Fermi of his life, Fermi questioned his faith in society at large to make wise choices about nuclear technology. He said: Fermi underwent an exploratory operation in Billings Memorial Hospital on 9 October 1954, after which he returned home. 50 days later, Fermi died at age 53 of stomach cancer in his home in Chicago. His memorial service was held at the University of Chicago chapel, where colleagues, Samuel K. Allison, Emilio Segrè, and Herbert L. Anderson spoke, mourning the loss of one of the world's "most brilliant and productive physicists." His body was interred at Oak Woods Cemetery. Fermi received
Enrico Fermi Y at Los Alamos, New Mexico. Arriving in September, Fermi was appointed an associate director of the laboratory, with broad responsibility for nuclear and theoretical physics, and was placed in charge of F Division, which was named after him. F Division had four branches: F-1 Super and General Theory under Teller, which investigated the "Super" (thermonuclear) bomb; F-2 Water Boiler under L. D. P. King, which looked after the "water boiler" aqueous homogeneous research reactor; F-3 Super Experimentation under Egon Bretscher; and F-4 Fission Studies under Anderson. Fermi observed the Trinity test on 16 July 1945, and conducted an experiment
