Frank Erhart Emmanuel Germann through eight editions between 1938 and 1985. His most influential textbook was "College Chemistry" (Englewood Cliffs, New Jersey: Prentice-Hall, 1952, 1958, 1965). A popular trimmed version was "Essentials of College Chemistry" (Prentice-Hall, 1960). Charles Franklin Metz, another Germann graduate student (M.S. 1928, Ph.D. 1936), was one of the twelve scientists who conducted the world’s first firing of a nuclear weapon, the “Trinity” test on New Mexico’s Alamogordo Bombing and Gunnery Range on Monday, July 16, 1945. On Monday, August 6, 1945, a nuclear bomb was detonated over Hiroshima, Japan. Later that week, on Thursday, August 9, 1945, a nuclear bomb
Nuclear testing at Bikini Atoll series was Castle Bravo, a new design utilizing a dry fuel thermonuclear hydrogen bomb. It was detonated at dawn on March 1, 1954. The 15 megaton (Mt) nuclear explosion far exceeded the expected yield of 4 to 8 Mt (6 Mt predicted), and was about 1,000 times more powerful than each of the atomic bombs dropped on Hiroshima and Nagasaki during World War II. The nuclear weapon was the most powerful device ever detonated by the United States (and just under one-third the energy of the Tsar Bomba, the largest ever tested). The scientists and military authorities were shocked by
