german nuclear weapons program
See also the entry for the KWIP in Appendix A and the entry for the HWA in Appendix B. Mehra and Rechenberg, Volume 6, Part 2, 2001, 1010–1011. North Korea and Pakistan currently have nuclear arsenals. Heinz Ewald, a member of the Uranverein, had proposed an electromagnetic isotope separator, which was thought applicable to U235 production and enrichment. Instead of pooling its resources, Nazi Germany … Mutual distrust existed between the German government and some scientists.[96][97]. [65][66] In mid-1940 Finkelnburg became an acting director of the NSDDB at Technische Hochschule, Darmstadt. The program was split up among nine major institutes where the directors dominated the research and set their own objectives. At the end of the war, the Allied powers competed to obtain surviving components of the nuclear industry (personnel, facilities, and materiel), as they did with the pioneering V-2 SRBM missile program. Essentially unlimited manpower and industrial resources. He was also head of the research department of the HWA, assistant secretary of the Science Department of the OKW, and Bevollmächtigter (plenipotentiary) for high explosives. [59], Members of the Uranverein, Wolfgang Finkelnburg, Werner Heisenberg, Carl Ramsauer, and Carl Friedrich von Weizsäcker were effective in countering the politicization of academia and effectively putting an end to the influence of the Deutsche Physik movement. German nuclear weapons program. The program eventually expanded into three main efforts: the Uranmaschine (nuclear reactor), uranium and heavy water production, and uranium isotope separation. Cited in Hentschel and Hentschel, 1996, p. 280, but omitted from the anthology. Two days earlier, on 22 April 1939, after hearing a colloquium paper by Wilhelm Hanle on the use of uranium fission in a Uranmaschine (uranium machine, i.e., nuclear reactor), Georg Joos, along with Hanle, notified Wilhelm Dames, at the Reichserziehungsministerium (REM, Reich Ministry of Education), of potential military applications of nuclear energy. [33], Over time, the HWA and then the RFR controlled the German nuclear weapon project. Unexpectedly there was a flash of light. The exploitation teams were under the Soviet Alsos and they were headed by Lavrentij Beria's deputy, Colonel General A. P. Zavenyagin. The meeting was a turning point in National Socialism's attitude towards science, as well as recognition that its policies which drove Jewish scientists out of Germany were a mistake, as the Reich needed their expertise. At the close of the war, physicists born between 1915 and 1925 were almost nonexistent. [61] Finkelnburg served in this capacity until the end of World War II. Kurt Diebner (13 May 1905 – 13 July 1964) was a German nuclear physicist who is well known for directing and administrating the German nuclear energy project, a secretive program aiming to build nuclear weapons for Nazi Germany during the course of World War II. Hentschel and Hentschel, 1996, Appendix F; see the entry for Bopp. nuclear-weapons program translation german, English - German dictionary, meaning, see also 'nuclear weapon',nuclear waste',nuclear war',nuclear power', example … A second effort began under the administrative purview of the Wehrmacht's Heereswaffenamt on 1 September 1939, the day of the invasion of Poland. During this time, Heisenberg came under vicious attack by the supporters of Deutsche Physik. The nuclear weapon project thereafter maintained its kriegswichtig (important for the war) designation and funding continued from the military. Hentschel and Hentschel, 1996, 369, Appendix F (see the entry for Nikolaus Riehl), and Appendix D (see the entry for Auergesellschaft). Document No. 6 physicists and physical chemists). Targets on the top of their list were the Kaiser-Wilhelm Institut für Physik (KWIP, Kaiser Wilhelm Institute for Physics), the Frederick William University (today, the University of Berlin), and the Technische Hochschule Berlin (today, the Technische Universität Berlin (Technical University of Berlin).[96][97][98]. Despite the genius of physicists such as Werner Heisenberg, the German nuclear weapon program was stymied by bureaucracy during World War II. Tube Alloys. 40 on p. 262. Karlsch alleged that Diebner's team conducted the first successful nuclear weapon test of some type (employing hollow charges for ignition) of nuclear-related device in Ohrdruf, Thuringia on 4 March 1945. The Soviet atomic bomb project (Russian: Советский проект атомной бомбы, Sovetskiy proyekt atomnoy bomby) was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during World War II.. Attachment III: The Crucial Importance of Theoretical Physics and Particularly Modern Theoretical Physics. The German scientists were cautious: while it was clear that they could build atomic bombs in principle, they would require a great deal of resources to do so and could not realize such weapons any time soon. Max Planck, the father of quantum theory, had been right in assessing the consequences of National Socialist policies. Unconditional government support from a certain point in time. Eventually, Himmler settled the Heisenberg affair by sending two letters, one to SS-Gruppenführer Reinhard Heydrich and one to Heisenberg, both on 21 July 1938. Instead of pooling its resources, Nazi Germany … For nuclear power decommissioning in modern Germany, see, Comparison of the Manhattan Project and the, Controversies regarding alleged nuclear tests, In 1944, Hahn received the Nobel Prize for Chemistry for the discovery of nuclear fission. Heisenberg had been lecturing to his students about the theory of relativity, proposed by the Jewish scientist Albert Einstein. For the Manhattan Project, the second condition was met on 9 October 1941 or shortly thereafter. Hentschel and Hentschel, 1996, 363–364 and Appendix F; see the entries for Esau, Harteck and Joos. The two women knew each other as a result of Heisenberg's maternal grandfather and Himmler's father being rectors and members of a Bavarian hiking club. Finkelnburg, invited five representatives to make arguments for theoretical physics and academic decisions based on ability, rather than politics: Letter to Bernhard Rust, 20 January 1942. Unconditional government support from a certain point in time. Werner Heisenberg When looking for a scientist to help lead their nuclear program at the beginning of the war, Germany decided Werner Heisenberg would be a value asset to their ultimate objective of creating the atomic bomb. Germany for a long time was thought to have fallen short of what was required to make an atomic bomb. [103], The joint United States, British, and Canadian Manhattan Project developed the uranium and plutonium atomic bombs. [38] Out of 26 German nuclear physicists cited in the literature before 1933, 50% emigrated. [28][29][30][31], Speer states that the project to develop the atom bomb was scuttled in the autumn of 1942. Also, the project was then essentially split up between a number of institutes, where the directors dominated the research and set their own research agendas. Tube Alloys. Graphite (carbon) as an alternative was not considered as Walther Bothe’s neutron absorption coefficient value for carbon was too high; probably due to the nitrogen in air between the graphite pieces having high neutron absorption. Also see the entry for the, Walker, 1993, 83–84, 170, 183, and Reference No. [65] Also, in part, it was Finkelnburg's role in organising this event that influenced Carl Ramsauer, as president of the Deutsche Physikalische Gesellschaft, to select Finkelnburg in 1941 as his deputy. This was the first accident that disrupted a nuclear energy assembly; cf. The German nuclear weapons project (German language: Uranprojekt; informally known as the Uranverein; English: Uranium Society or Uranium Club) was a scientific effort led by Germany to develop and produce nuclear weapons during World War II. The program eventually expanded into three main efforts: the Uranmaschine (nuclear reactor), uranium and heavy water production, and uranium isotope separation. Iran using third countries and front companies to acquire WMD technology, says intelligence agency of Germany’s Hesse state. Topics related to both German nuclear weapons program and Tube Alloys. In order to put pressure on Bopp to evacuate the KWIP to France, the French Naval Commission imprisoned him for five days and threatened him with further imprisonment if he did not cooperate in the evacuation. [57] Those drafted included Uranverein members Paul O. Müller and Karl-Heinz Höcker. "I suddenly saw something,' she said ... "it was as bright as hundreds of bolts of lightning, red on the inside and yellow on the outside, so bright you could've read the newspaper. After reading a June 1939 paper by Siegfried Flügge, on the technical use of nuclear energy from uranium,[11][12] Nikolaus Riehl, the head of the scientific headquarters at Auergesellschaft, recognized a business opportunity for the company, and in July he went to the HWA (Heereswaffenamt, Army Ordnance Office) to discuss the production of uranium. German physical chemist from Breslau (Wrocław), Silesia. ("With friendly greetings and, Heil Hitler! Though the scientific solution was present, it would have taken all of Germany's production resources to produce a bomb, and then no sooner than 1947. Those of Jewish heritage who did not leave were quickly purged from German institutions, further thinning the ranks of academia. Hentschel and Hentschel, 1996, Appendix F; see the entry for Thiessen. Quite the same Wikipedia. In 2007, Karlsch, with Heinko Petermann, published a sequel to Hitler's Bombe, elaborating on issues raised in his first book: Für und Wider "Hitlers Bombe" (Münster; Waxmann). In 1971, the reports were declassified and returned to Germany. [32][33] Taking Ewald's suggestion he began building a prototype for the RPM. [72][73][74][75][76], The best known US denial and exploitation effort was Operation Paperclip, a broad dragnet that encompassed a wide range of advanced fields, including jet and rocket propulsion, nuclear physics, and other developments with military applications such as infrared technology. This was the case of Finkelnburg. However, in order to do this they were, as were many scientists, caught between autonomy and accommodation. This, combined with information gathered in the same month through an Alsos team in Strasbourg, confirmed that the Oranienburg plant was involved in the production of uranium and thorium metals. Günter Wirths, while not a member of the Uranverein, worked for Riehl at the Auergesellschaft on reactor-grade uranium production and was also sent to the Soviet Union. In 1944, when most of the KWIP was evacuated to Hechingen in Southern Germany due to air raids on Berlin, he went there too, and he was the Institute's Deputy Director there. Hentschel and Hentschel, 1996, Appendix F; see the entry for Bopp. [98][99][100] By the end of 1941 it was already apparent that the German nuclear weapon project would not make a decisive contribution to ending the German war effort in the near term, and control of the project was relinquished by the Heereswaffenamt (HWA, Army Ordnance Office) to the Reichsforschungsrat (RFR, Reich Research Council) in July 1942. On 15 March 1945, 612 B-17 Flying Fortress bombers of the Eighth Air Force dropped 1,506 tons of high-explosive and 178 tons of incendiary bombs on the plant. Document No. (6 physicists), Measurement of nuclear constants. Alternate History: Nazi Germany Could Have Been the First to Build Nuclear Weapons. When the American Alsos Mission evacuated Hechingen and Haigerloch, near the end of World War II, French armed forces occupied Hechingen. Speer felt it was better that the whole thing should be dropped and the Fuehrer also reacted that way. [40] These 14 scientists were: Hans Bethe, Felix Bloch, Max Born, Albert Einstein, James Franck, Peter Debye, Dennis Gabor, Fritz Haber, Gerhard Herzberg, Victor Hess, George de Hevesy, Erwin Schrödinger, Otto Stern, and Eugene Wigner. [46] These 15 scientists were: Hans Bethe, Felix Bloch, Max Born, Albert Einstein, James Franck, Heinrich Gerhard Kuhn, Peter Debye, Dennis Gabor, Fritz Haber, Gerhard Herzberg, Victor Hess, George de Hevesy, Erwin Schrödinger, Otto Stern, and Eugene Wigner. The nuclear-sharing arrangement reportedly allows NATO member states without nuclear weapons to participate in planning and training for the use of nuclear weapons, according to DW. [64][65][66][67][68], A general US denial and exploitation effort was Operation Paperclip. Goudsmit, the chief scientific advisor to Operation Alsos, thought von Laue might be beneficial to the postwar rebuilding of Germany and would benefit from the high level contacts he would have in England. In addition to exploitation, denial of these technologies, their personnel, and related materials to rival allies was a driving force of their efforts. Zimmer's path to work on the Soviet atomic bomb project was through a prisoner of war camp in Krasnogorsk, as was that of his colleagues Hans-Joachim Born and Alexander Catsch from the Kaiser-Wilhelm Institut für Hirnforschung (KWIH, Kaiser Wilhelm Institute for Brain Research, today the Max-Planck-Institut für Hirnforschung), who worked there for N. V. Timofeev-Resovskij, director of the Abteilung für Experimentelle Genetik (Department of Experimental Genetics). Diebner, throughout the life of the nuclear weapon project, had more control over nuclear fission research than did Walther Bothe, Klaus Clusius, Otto Hahn, Paul Harteck, or Werner Heisenberg.[34][35]. After reading a June 1939 paper by Siegfried Flügge, on the technical use of nuclear energy from uranium,[11][12] Nikolaus Riehl, the head of the scientific headquarters at Auergesellschaft, recognized a business opportunity for the company, and in July he went to the HWA (Heereswaffenamt, Army Ordnance Office) to discuss the production of uranium. Many of the scientists not working with the main institutes stopped working on nuclear fission and devoted their efforts to more pressing war related work. 40 on p. 262. This had immediate deleterious effects on the physics capabilities of Germany. Since the plant was to be in the future Soviet zone of occupation and the Red Army's troops would get there before the Allies, General Leslie Groves, commander of the Manhattan Project, recommended to General George Marshall that the plant be destroyed by aerial bombardment, in order to deny its uranium production equipment to the Soviets. 6 physicists and physical chemists). Hentschel and Hentschel, 1996, Appendix F; see entry for Ardenne. Also see p. 372 and footnote No. The production of heavy water was already under way in Norway when the Germans invaded on 9 April 1940. In 1933, Planck, as president of the Kaiser Wilhelm Gesellschaft (Kaiser Wilhelm Society), met with Adolf Hitler. During his imprisonment, the spectroscopist Hermann Schüler, who had a better relationship with the French, persuaded the French to appoint him as Deputy Director of the KWIP. Hentschel and Hentschel, 1996, 369, Appendix F, see the entry for Riehl, and Appendix D, see the entry for Auergesellschaft. Many of the scientists not working with the main institutes stopped working on nuclear fission and devoted their efforts to more pressing war related work. [90][91], Von Ardenne, who had worked on isotope separation for the Reichspostministerium (Reich Postal Ministry), was also sent to the Soviet Union to work on their atomic bomb project, along with Gustav Hertz, Nobel laureate and director of Research Laboratory II at Siemens, Peter Adolf Thiessen, director of the Kaiser-Wilhelm Institut für physikalische Chemie und Elektrochemie (KWIPC, Kaiser Wilhelm Institute for Chemistry and Electrochemisty, today the Fritz Haber Institute of the Max-Planck Society), and Max Volmer, director of the Physical Chemistry Institute at the Berlin Technische Hochschule (Technical University of Berlin), who all had made a pact that whoever first made contact with the Soviets would speak for the rest. Attachment I: American Physics Outdoes German Physics. German nuclear weapons program. [25] On 9 June 1942, Adolf Hitler issued a decree for the reorganization of the RFR as a separate legal entity under the Reichsministerium für Bewaffnung und Munition (RMBM, Reich Ministry for Armament and Ammunition, after late 1943 the Reich Ministry for Armament and War Production); the decree appointed Reich Marshal Hermann Göring as the president. The process was lengthy due to academic and political differences between the Munich Faculty's selection and that of both the Reichserziehungsministerium (REM, Reich Education Ministry) and the supporters of Deutsche Physik. At one point, Heisenberg's mother visited Himmler's mother to help bring a resolution to the affair. Klaus Clusius. [23] The reorganization was done under the initiative of Minister Albert Speer of the RMBM; it was necessary as the RFR under Minister Bernhard Rust was ineffective and not achieving its purpose. Noté /5. A strong initial drive, by a small group of scientists, to launch the project. This was picked up by Manfred von Ardenne, who ran a private research establishment. [82], With the interest of the Heereswaffenamt (HWA, Army Ordnance Office), Nikolaus Riehl, and his colleague Günter Wirths, set up an industrial-scale production of high-purity uranium oxide at the Auergesellschaft plant in Oranienburg. German physicists who worked on the Uranverein and were sent to the Soviet Union to work on the Soviet atomic bomb project included: Werner Czulius, Robert Döpel, Walter Herrmann, Heinz Pose, Ernst Rexer, Nikolaus Riehl, and Karl Zimmer. Schumann was director of the Physics Department II at the Frederick William University (later, University of Berlin), which was commissioned and funded by the Oberkommando des Heeres (OKH, Army High Command) to conduct physics research projects. German nuclear weapons program. The German “uranium project” began in earnest shortly after Germany’s invasion of Poland in September 1939, when German Army Ordnance established a research program led by the Army physicist Kurt Diebner to investigate the military applications of fission. As to condition four, the high priority allocated to the Manhattan Project allowed for the recruitment and concentration of capable scientists on the project. The seven power stations still in … [25][26][27][28], Over time, the HWA and then the RFR controlled the German nuclear weapon project. [26] The reorganization was done under the initiative of Minister Albert Speer of the RMBM; it was necessary as the RFR under Bernhard Rust the Minister of Science, Education and National Culture was ineffective and was not achieving its purpose. But there were so few staff or groups that they could not repeat experiments to check results. ("With friendly greetings and, Heil Hitler! Müller was not a theoretical physicist, had not published in a physics journal, and was not a member of the Deutsche Physikalische Gesellschaft (DPG, German Physical Society); his appointment as a replacement for Sommerfeld was considered a travesty and detrimental to educating a new generation of theoretical physicists.
