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
History of nuclear weapons found a rough schematic showing a Nazi nuclear bomb. In March 1945, a German scientific team was directed by the physicist Kurt Diebner to develop a primitive nuclear device in Ohrdruf, Thuringia. Last ditch research was conducted in an experimental nuclear reactor at Haigerloch. On April 12, after Roosevelt's death, Vice-President Harry S. Truman assumed the presidency. At the time of the unconditional surrender of Germany on May 8, 1945, the Manhattan Project was still months away from producing a working weapon. Because of the difficulties in making a working plutonium bomb, it was decided that there should be a
