Kernphysikalische Forschungsberichte
''Kernphysikalische Forschungsberichte'' (''Research Reports in Nuclear Physics'') was an internal publication of the German ''Uranverein'', which was initiated under the ''Heereswaffenamt'' (Army Ordnance Office) in 1939; in 1942, supervision of the ''Uranverein'' was turned over to the Reichsforschungsrat under the Reichserziehungsministerium. Reports in this publication were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. Many of the reports are available at the Karlsruhe Nuclear Research Center and the Niels Bohr Library of the American Institute of Physics. Many of them are reprinted and transcribed in the book "''Collected Works / Gesammelte Werke''" listed below which is available in most libraries. There are reports n ...

German Nuclear Energy Project
The Uranverein ( en, "Uranium Club") or Uranprojekt ( en, "Uranium Project") was the name given to the project in Germany to research nuclear technology, including nuclear weapons and nuclear reactors, during World War II. It went through several phases of work, but in the words of historian Mark Walker, it was ultimately "frozen at the laboratory level" with the "modest goal" to "build a nuclear reactor which could sustain a nuclear fission chain reaction for a significant amount of time and to achieve the complete separation of at least tiny amount of the uranium isotopes." The scholarly consensus is that it failed to achieve these goals, and that despite fears at the time, the Germans had never been close to producing nuclear weapons. The first effort started in April 1939, just months after the discovery of nuclear fission in December 1938, but ended only months later shortly ahead of the German invasion of Poland, when many notable physicists were drafted into the ''Wehr ...

Werner Heisenberg
Werner Karl Heisenberg () (5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the main pioneers of the theory of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, his matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics". Heisenberg also made contributions to the theories of the hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles. He was a principal scientist in the German nuclear weapons program during World War II. He was also instrumental in planning the first West German nuclear reactor at Karlsruhe, together with a research reactor in Munich, in 1957. Following World War II, he was appointed ...

Wolfgang Finkelnburg
Wolfgang Karl Ernst Finkelnburg (5 June 1905 – 7 November 1967) was a German physicist who made contributions to spectroscopy, atomic physics, the structure of matter, and high-temperature arc discharges. His vice-presidency of the Deutsche Physikalische Gesellschaft 1941-1945, was influential in that organization’s ability to assert its independence from National Socialist policies. Education Finkelnburg began his studies of physics and mathematics in 1924 at the University of Tübingen and the University of Bonn. He acquired his doctorate in 1928 under Heinrich Konen, and remained as Konen’s teaching assistant.

Walther Bothe
Walther Wilhelm Georg Bothe (; 8 January 1891 – 8 February 1957) was a German nuclear physicist, who shared the Nobel Prize in Physics in 1954 with Max Born. In 1913, he joined the newly created Laboratory for Radioactivity at the Reich Physical and Technical Institute (PTR), where he remained until 1930, the latter few years as the director of the laboratory. He served in the military during World War I from 1914, and he was a prisoner of war of the Russians, returning to Germany in 1920. Upon his return to the laboratory, he developed and applied coincidence methods to the study of nuclear reactions, the Compton effect, cosmic rays, and the wave–particle duality of radiation, for which he would receive the Nobel Prize in Physics in 1954. In 1930 he became a full professor and director of the physics department at the University of Giessen. In 1932, he became director of the Physical and Radiological Institute at the University of Heidelberg. He was driven out of this posit ...

In 1934, he became an ''Assistant'' (Assistant) at Göttingen. In 1937, Bopp completed his doctorate on the subject of Compton scattering under the physicist Fritz Sauter. From 1936 to 1941, he was a teaching assistant at Breslau University. In 1941, Bopp completed his ''Habilitationsschrift'' under Erwin Fues on the subject of a consistent field theory of the electron.Hentschel a ...

Karl Zimmer
Karl Günter Zimmer (12 July 1911 – 29 February 1988) was a German physicist and radiation biologist, known for his work on the effects of ionizing radiation on DNA. In 1935, he published the major work, ''Über die Natur der Genmutation und der Genstruktur'', with N. V. Timofeev-Resovskij, and Max Delbrück; it was considered to be a major advance in understanding the nature of gene mutation and gene structure. In 1945, he was sent to the Soviet Union to work on their atomic bomb project. In 1955, he left Russia and eventually went to West Germany. Education Zimmer obtained his doctorate in 1934 with a thesis on photochemistry.VNIITF). Penzina is cited as head of the VNIITF Archive in Snezhinsk.)

Robert Döpel
Georg Robert Döpel (3 December 1895 – 2 December 1982) was a German experimental nuclear physicist.

Soviet Atomic Bomb Project
The Soviet atomic bomb project was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by German, American, and British scientists, Russian physicist Georgy Flyorov suspected that the Allied powers had secretly been developing a "superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the German invasion of the Soviet Union and remained largely composed of the intelligence gathering from the Soviet spy rings working in the U. ...
