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 first test was dropped from an aircraft and detonated above the target fleet. The second, "Baker", was suspending under a barge. It produced a large Wilson cloud and contaminated all of the target ships. Chemist Glenn T. Seaborg, the longest-serving chairman of the Atomic Energy Commission, called the second test "the world's first nuclear disaster." The second series of tests in 1954 was codenamed Operation Castle. The first detonation, Castle Bravo, was a new design utilizing a dry fuel thermonuclear hydrogen bomb. It was detonated at dawn on March 1, 1954. Scientists miscalculated and the 15 megaton (Mt) nuclear explosion
