Hitler responded with a rant against Jews and Planck could only remain silent and then take his leave. Early in 1942, as president of the DPG, Ramsauer, on Felix Klein's initiative and with the support of Ludwig Prandtl, submitted a petition to Reich Minister Bernhard Rust, at the Reichserziehungsministerium (Reich Education Ministry). " Erhard Milch asked how long America would take and was told 1944 though the group between ourselves thought it would take longer, three or four years. As one German scientist exclaimed, it must have taken "factories large as the United States to make that much uranium-235!". ("With friendly greetings and, Heil Hitler! Although it is now clear that the German nuclear program never came close to producing a bomb, there is no doubt that it provided an impetus for the Manhattan Project. , When it was apparent that the nuclear weapon project would not make a decisive contribution to ending the war in the near term, control of the KWIP was returned in January 1942 to its umbrella organization, the Kaiser-Wilhelm Gesellschaft (KWG, Kaiser Wilhelm Society, after World War II the Max-Planck Gesellschaft). Unconditional government support from a certain point in time. Heisenberg’s frustrations were evident when, at Farm Hall, he remarked, “The point is that the whole structure of the relationship between the scientist and the state in Germany was such that although we were not 100% anxious to do it, on the other hand we were so little trusted by the state that even if we had wanted to do it, it would not have been easy to get it through.”. On the purely scientific and technical side, did Heisenberg understand accurately how an atomic bomb would work and how to make it? As Chief of Foreign Intelligence in the Manhattan Project, Robert Furman coordinated and was a part of the Alsos Mission, conducting epsionage missions across Europe to interrogate Italian and German scientists, locate uranium, and determine how far the Nazis had proceeded with their atomic bomb project. German historian Klaus Hentschel summarizes the organizational differences as: In terms of financial and human resources, the comparisons between the Manhattan Project and the Uranverein are stark. An immediate consequence upon passage of the law was that it produced both quantitative and qualitative losses to the physics community. When the American Alsos Mission evacuated Hechingen and Haigerloch, near the end of World War II, French armed forces occupied Hechingen. And here there is indeed massive uncertainty and disputation. Both sides wanted to use scientists from Nazi Germany to further their own new technologies.  Mutual distrust existed between the German government and some scientists. 2, in Moscow, and included Yulij Borisovich Khariton, Isaak Konstantinovich Kikoin, and Lev Andreevich Artsimovich. Heavy water production and isotope production. The first successful test detonation, the Trinity Test, in New Mexico only occurred on July 16, 1945. Often forgotten in the wake of Hiroshima and Nagasaki is that the Manhattan Project was originally conceived for the war in Europe, but the bomb was not ready for operational use in time. 50 on p. 372. Victor Weisskopf recounted Bohr telling him, “Heisenberg wanted to know if Bohr knew anything about the nuclear program of the Allies. Not only was heavy water a less effective moderator than graphite, it made the German program reliant on the Norwegian plant. , Work of the American Operation Alsos teams, in November 1944, uncovered leads which took them to a company in Paris that handled rare earths and had been taken over by the Auergesellschaft. The Farm Hall transcripts also show the ignorance of Walther Gerlach, the scientific liaison to the German government, an important link in coordinating the project. Nine of the prominent German scientists who published reports in Kernphysikalische Forschungsberichte as members of the Uranverein were picked up by Operation Alsos and incarcerated in England under Operation Epsilon: Erich Bagge, Kurt Diebner, Walther Gerlach, Otto Hahn, Paul Harteck, Werner Heisenberg, Horst Korsching, Carl Friedrich von Weizsäcker, and Karl Wirtz. Riehl visited the site with the Soviets and said that the facility was mostly destroyed. Hentschel and Hentschel, 1996, Appendix F; see the entry for Thiessen. The group's work was discontinued in August 1939, when the three were called to military training.. One of the 664 two-inch uranium cubes produced in Nazi Germany during a failed attempt to create a nuclear reactor in World War II. 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 Wehrmacht. ", (June 2008) Annotated bibliography on the German atomic bomb project from the Alsos Digital Library for Nuclear Issues, Institute for Physics Chemistry and Electrochemistry, Universität Hamburg, Department of Physical Chemistry, Universität Leipzig, Institute for Physics; Institute for Theoretical Physics, https://en.wikipedia.org/w/index.php?title=German_nuclear_weapons_program&oldid=992468204, Articles containing explicitly cited English-language text, Articles with specifically marked weasel-worded phrases from July 2020, Wikipedia articles containing unlinked shortened footnotes, Creative Commons Attribution-ShareAlike License. Berlin had been a location of many German scientific research facilities. Von Ardenne had also conducted research on isotope separation. The allegations of sabotage carry little weight. No orders were given to build atomic bombs” (Powers x). They had the classification (uk) not (uk, indispensable) and not even Kurt Diebner, managing director of the KWIP, could stop their call-up. Realistically, based on the timeline of the atomic bomb creation, there seemed little chance that Germany would be a viable target. The HWA eventually provided an order for the production of uranium oxide, which took place in the Auergesellschaft plant in Oranienburg, north of Berlin. The use of the term “atomic bomb” in the titles of these books is entirely misleading – an example of advertising hype by German publishing houses. Uranium cubes on chains in the model of the reactor at Haigerloch. In 1971, the reports were declassified and returned to Germany. BBC News, Berlin.  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. Max Planck, the father of quantum theory, had been right in assessing the consequences of National Socialist policies. The experience with Germany after the First World War had persuaded them that a mere armistice would constitute a betrayal of future generations if an even larger war occurred 20 years down the line. At the close of the war, physicists born between 1915 and 1925 were almost nonexistent.  Out of 26 German nuclear physicists cited in the literature before 1933, 50% emigrated. This second Uranverein was formed on 1 September 1939, the day World War II began, and had its first meeting on 16 September 1939. Other scientists left in protest, significantly decreasing the number of experts available to work on a German bomb. In addition to exploitation, denial of these technologies, their personnel, and related materials to rival allies was a driving force of their efforts. Any other assumption would have been unsound and dangerous” (Norris 295). Nevertheless, German politicians have continued to assert that their eventual goal is the "withdrawal of tactical nuclear weapons stationed in Germany and Europe. The politicization of the universities, along with the demands for manpower by the German armed forces (many scientists and technical personnel were conscripted, despite possessing useful skills), substantially reduced the number of able German physicists.. It was not until 1944 that Werner Osenberg [de], head of the planning board at the Reichsforschungsrat (RFR, Reich Research Council), was able to initiate calling back 5000 engineers and scientists from the front to work on research categorized as kriegsentscheidend (decisive for the war effort). Speer felt it was better that the whole thing should be dropped and the Führer also reacted that way." Hentschel and Hentschel, 1966, Appendix F; see the entry for Carl Ramsauer. Following their invasion of Norway in 1940, the Germans assumed control of the Norsk Hydro heavy water plant at Vemork. The G-1 experiment performed at the HWA testing station, under the direction of Kurt Diebner, had lattices of 6,800 uranium oxide cubes (about 25 tons), in the nuclear moderator paraffin. Hentschel and Hentschel, 1996, Appendix C; see the entry for the NSDDB. The Munich Faculty was firmly behind these candidates, with Heisenberg as their first choice. Sceptics agree the book sheds new light on Nazi nuclear experiments. Germany began its secret program, called Uranverein, or “uranium club,” in April 1939, just months after German scientists Otto Hahn and Fritz Strassmann had inadvertently discovered fission.  Their article was published on 6 January 1939. It is true that the radiation effects of the atomic bomb provided a grisly dividend, which the US leaders did not anticipate. Paul Peter Ewald, a member of the Uranverein, had proposed an electromagnetic isotope separator, which was thought applicable to 235U production and enrichment. It provides a look at what surprisingly turned out to be an Achilles' heel for Hitler - the misuse of science and scientists in the service of the Third Reich.  The University of Göttingen had 45 dismissals from the staff of 1932–1933, for a loss of 19%. Despite what most of the members here claim, the exodus of Jewish scientists did not seriously impede the Germans on their quest towards an atom bomb. Bopp did not get along with them and described the initial French policy objectives towards the KWIP as exploitation, forced evacuation to France, and seizure of documents and equipment.  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. There was even consideration of kidnapping Werner Heisenberg in Switzerland in 1942, although this plan never came to fruition. According to Berlin historian Rainer Karlsch in his book Hitler’s Bomb, German scientists carried out three nuclear weapons tests just before the end … This was the case of Finkelnburg.  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. For example, his research on nuclear physics and high-frequency technology was financed by the Reichspostministerium (RPM, Reich Postal Ministry), headed by Wilhelm Ohnesorge. Over 100,000 German translations of English words and phrases.  Essentially, they would have to legitimize the National Socialist system by compromise and collaboration.. The bigger problem, however, lay in lack of support. 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). Historians continue to debate what would have happened had the Germans invested significant resources in their nuclear program, and if it could have changed the outcome of the war. Müller died on the Russian front, but Höcker was repatriated in poor health in 1942. In 1928, von Ardenne had come into his inheritance with full control as to how it could be spent, and he established his private research laboratory the Forschungslaboratoriums für Elektronenphysik, in Berlin-Lichterfelde, to conduct his own research on radio and television technology and electron microscopy. (John T. Consoli/University of Maryland) By Erin Blakemore 278–281. All rights reserved. The play explores three scenarios where Heisenberg discusses his dilemma with Bohr, but leaves the matter for audiences to decide what Heisenberg actually believed and intended to do. For instance an error was made in an experiment to test the suitability of CARBON as a moderator in reactors.  The hope was that Göring would manage the RFR with the same discipline and efficiency as he had the aviation sector. “I don't believe a word of the whole thing,” declared Werner Heisenberg, the scientific head of the German nuclear program, after hearing the news that the United States had dropped an atomic bomb on Hiroshima. During his imprisonment, the spectroscopist Hermann Schüler [de] , who had a better relationship with the French, persuaded the French to appoint him as Deputy Director of the KWIP. There was no plan. However, Sommerfeld stayed on as his own temporary replacement during the selection process for his successor, which took until 1 December 1939. The full interview transcript can be found on "Voices of the Manhattan Project.". HWA control of the project was subsequently passed to the RFR in July 1942. 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. Bombarding uranium with neutrons could transform the material into a smaller element, barium. Even with all four of these conditions in place the Manhattan Project succeeded only after the war in Europe had been brought to a conclusion. The U.S. forced Wernher von Braun and Werner Heisenberg, two key scientists in the German nuclear project, to collaborate.  While the technical outcome may have been thin, it was a political victory against deutsche Physik. To Heisenberg, Himmler said the letter came on recommendation of his family and he cautioned Heisenberg to make a distinction between professional physics research results and the personal and political attitudes of the involved scientists. This had immediate damaging effects on the physics capabilities of Germany. Join Today as an Atomic History Patron Member, Alex Wellerstein "Historical thoughts on Michael Frayn’s Copenhagen". A second meeting was held soon thereafter and included Klaus Clusius, Robert Döpel, Werner Heisenberg, and Carl Friedrich von Weizsäcker. On 7 April, the Law for the Restoration of the Professional Civil Service was enacted; this law, and its subsequent related ordinances, politicized the education system in Germany. In December 1938, German chemist Otto Hahn and his assistant Fritz Strassmann sent a manuscript to the German science journal Naturwissenschaften ("Natural Sciences") reporting that they had detected and identified the element barium after bombarding uranium with neutrons. This was picked up by Manfred von Ardenne, who ran a private research establishment. Individual reports are cited on the pages for some of the research participants in the Uranverein; see for example Friedrich Bopp, Kurt Diebner, Klara Döpel, Robert Döpel, Siegfried Flügge, Paul Harteck, Walter Herrmann, Karl-Heinz Höcker, Fritz Houtermans, Horst Korsching, Georg Joos, Heinz Pose, Carl Ramsauer, Fritz Strassmann, Karl Wirtz, and Karl Zimmer. Also see footnote No. Most important was their experimental proof of an effective neutron increase in April 1942. It was a German scientist, Otto Hahn, who first split the atom in 1938. This 'fission' of an atom changed the world forever. The most influential people were Kurt Diebner, Abraham Esau, Walther Gerlach, and Erich Schumann. The production of heavy water was already under way in Norway when the Germans invaded on 9 April 1940. , The second Uranverein began after the HWA squeezed out the Reichsforschungsrat (RFR, Reich Research Council) of the REM and started the formal German nuclear weapons project under military auspices. See also Manfred von Ardenne, Hentschel and Hentschel, 1996, Appendix E; see the entry for, An Italian working in Rome, Fermi left after anti-semitic policies were introduced in Italy, The eight students, assistants, and colleagues of the theoretical physicist Max Born who left Europe found work on the. The Norwegian production facilities for heavy water were quickly secured (though some heavy water had already been removed) and improved by the Germans. Letter to Bernhard Rust, 20 January 1942. Attachment IV: Refuting Allegations that Modern Theoretical Physics is a Product of the Jewish Spirit. He wanted to propose a scientists’ decision not to work on the bomb, and he wanted to invite Bohr to come to Germany to establish better relations” (Powers 125). Though the scientific solution was there, it would have taken all of Germany's production resources to produce a bomb, and then no sooner than 1947. Finally, on February 28, 1943, a Norwegian commando raid destroyed the facility’s heavy water section in Operation Gunnerside, resulting in the loss of 500kg of heavy water. Finkelnburg invited five representatives to make arguments for theoretical physics and academic decisions based on ability, rather than politics: Carl Friedrich von Weizsäcker. 93 in Hentschel and Hentschel, 1996, pp.  Those drafted included Uranverein members Paul O. Müller and Karl-Heinz Höcker. 85 on p. 247. The truth is that National Socialist Germany could not possibly have built a weapon like the atomic bombs dropped on Hiroshima or Nagasaki. Numerically, it has been estimated that a total of 1,145 university teachers, in all fields, were driven from their posts, which represented about 14% of the higher learning institutional staff members in 1932–1933. Significant work on the German project was halted in June of 1942. Hentschel and Hentschel, 1996, Appendix F; see the entry for Bopp. , Over time, the HWA and then the RFR controlled the German nuclear weapon project. 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. Hentschel and Hentschel, 1996, 369, Appendix F, see the entry for Riehl, and Appendix D, see the entry for Auergesellschaft. In 1933, Planck, as president of the Kaiser Wilhelm Gesellschaft (Kaiser Wilhelm Society), met with Adolf Hitler. However, the replacement of Sommerfeld by Wilhelm Müller on 1 December 1939 was a victory of politics over academic standards. Schumann was one of the most powerful and influential physicists in Germany. 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 program. The scientists knew this to be the case because they were refugees from Germany, a large number of them, and they had studied under the Germans before the war broke out.” Manhattan Project physicist Leona Marshall Libby also recalled, “I think everyone was terrified that we were wrong, and the Germans were ahead of us.… Germany led the civilized world of physics in every aspect, at the time war set in, when Hitler lowered the boom. All four eventually worked for Riehl in the Soviet Union at Laboratory B in Sungul'. Robert Furman, assistant to General Leslie Groves and the Chief of Foreign Intelligence for the Manhattan Project, described how “the Manhattan Project was built on fear: fear that the enemy had the bomb, or would have it before we could develop it. Eugene Wigner – Director of Theoretical Studies, John von Neumann – LASL consultant on implosion mechanism for the plutonium bomb. This was simply not the case with the German project. The most influential people in the Uranverein were Kurt Diebner, Abraham Esau, Walther Gerlach, and Erich Schumann; Schumann was one of the most powerful and influential physicists in Germany. Fearing that the Germans would use the heavy water for their atomic bomb program, Allied forces conducted a series of strategic bombings against the plant. This move allowed the Americans to take into custody a large number of German scientists associated with nuclear research. Also at this time, the Kaiser-Wilhelm Institut für Physik (KWIP, Kaiser Wilhelm Institute for Physics, after World War II the Max Planck Institute for Physics), in Berlin-Dahlem, was placed under HWA authority, with Diebner as the administrative director, and the military control of the nuclear research commenced. By Ray Furlong. Abraham Esau was appointed on 8 December 1942 as Hermann Göring's Bevollmächtigter (plenipotentiary) for nuclear physics research under the RFR; in December 1943, Esau was replaced by Walther Gerlach.
