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
B83 nuclear bomb in the Grenadier Tierra nuclear weapon test on 15 December 1984, at a reduced yield of 80 kilotonnes due to the Threshold Test Ban Treaty. With the dismantling of the last B53 bomb in 2011, the B83 became the highest yield nuclear weapon in the U.S. arsenal. The bomb is long, with a diameter of . The actual nuclear explosive package, judging from published drawings, occupies some in the forward part of the bomb case. The bomb weighs approximately . The location of the lifting lugs shows that the greater part of the total mass is contained in the nuclear
