Erich Schumann

Erich Schumann

Erich Schumann (5 January 1898 – 25 April 1985) was a German physicist who specialized in acoustics and explosives, and had a penchant for music, as he was a grandson of the classical composer Robert Schumann. He was a general officer in the army and a professor at the University of Berlin and the Technical University of Berlin. When Adolf Hitler came to power he joined the Nazi Party. During World War II, his positions in the Army Ordnance Office and the Army High Command made him one of the most powerful and influential physicists in Germany. He ran the German nuclear energy program from 1939 to 1942, when the army relinquished control to the Reich Research Council. His role in the project was obfuscated after the war by German physics community apologia. The publication of his book on the military’s role in the project was not allowed by the British occupation authorities. He was director of the Helmholtz Institute of Sound Psychology and Medical Acoustics.

Education

Schumann, a grandson of the classical music composer Robert Schumann, was born in Potsdam, Brandenburg. He studied at the Frederick William University (today the Humboldt University of Berlin) under the acoustician and musicologist Carl Stumpf and the physicist Max Planck. In 1922, he received his doctorate there in systematic musicology (acoustics). He completed his Habilitation on acoustics there in 1929; members of his Habilitation committee for experimental and theoretical physics included the eminent scientists Walther Nernst, Max von Laue, and Max Planck . [ [http://de.wikipedia.org/wiki/Erich_Schumann_(Wissenschaftler) Schumann] - German Wikipedia.] [ Macrakis, 1993, 79.] [ Powers, 1993, 130-131.]

Career

Overview

From 1922, Schumann was a physicist at the "Reichswehrministerium" (RWM, Reich Ministry of Defense), which became the "Reichskriegsministerium" (RKM, Reich Ministry of War) in 1939. He passed the "Referendar" (civil service exam) in 1926. From 1929, he was head of the RWM Central Science Office and from 1932 ministerial councilor there. [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann.]

In 1929, when he completed his Habilitation at the University of Berlin, he was appointed lecturer of systematic musicology (acoustics). In 1931, he became an extraordinarius professor of experimental and theoretical physics there, and in 1933 he became an ordinarius professor of applied physics and systematic musicology. Schumann taught courses on acoustics and explosives, his areas of research. Schumann was the doctoral advisor to Wernher von Braun, who was awarded his doctorate in 1934. [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann.] [ Macrakis, 1993, 79.] [ Neufeld, Michael J. "Von Braun: Dreamer of Space, Engineer of War" (Knopf, 2007) p. 61.]

In 1933, the year Adolf Hitler came to power, Schumann became a member of the Nazi Party. [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann.]

From 1933 until 1945, Schumann was director of the newly established Physics Department II of the University of Berlin, which was commissioned by the "Oberkommando des Heeres" (OKW, Army High Command) to conduct research projects they funded. Concurrently, from 1934, he was head of the research department for the "Heereswaffenamt" (HWA, Army Ordnance Office) and assistant secretary in the Science Department of the RKM, then from 1938 to 1945 of the OKW. Additionally, in the autumn of 1938, he was appointed an ordinarius professor of ballistics and military technology at the "Technische Hochschule Berlin" (today the Technical University of Berlin). From 1942 to 1945, he was on the "Reichsforschungsrat" (RFR, Reich Research Council) and was also the "Bevollmächtiger" (plenipotentiary) for high explosives. [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann. Also see Hentschel and Hentschel, 1996, p. 207, footnote #1; Erich Schumann described his functions in the article he wrote: Erich Schumann "Wehrmacht und Froschung" in Richard Donnevert (editor) "Wehrmact und Partei" second expanded edition, (Barth, 1939) 133-151.]

Schumann, a general officer in the army and an ordinarius professor in academia, skillfully projected his power as a science policymaker for Germany. He enjoyed both roles, as remembered by the nuclear physicist Georg Hartwig, and dressed appropriately to gain advantage. For example, when he met with academia representatives, he wore his military uniform and saluted. When meeting with military officials, he dressed "in mufti" and was introduced as "Herr Professor Doktor". [ Powers, 1993, 130-131.] [ Walker, 1993, 47.]

Uranverein

From September 1939 to 1942 the HWA controlled the German nuclear energy project, also known at the "Uranverein" (Uranium Club); in 1942 control was turned over to the RFR. The most influential people in the project were Schumann, Abraham Esau, [ Abraham Esau was appointed on 8 December 1942 as Hermann Göring’s "Bevollmächtiger" (plenipotentiary) for nuclear physics research under the "Reichsforschungsrat"; in December 1943, Esau was replaced by Walther Gerlach. See Hentschel and Hentschel, 1996, Appendix F; see the entries for Esau and Gerlach.] Walther Gerlach, [ In December 1943, Abraham Esau was replaced by Walther Gerlach as Hermann Göring’s "Bevollmächtiger" (plenipotentiary) for nuclear physics research under the "Reichsforschungsrat". See Hentschel and Hentschel, 1996, Appendix F; see the entries for Esau and Gerlach.] and Kurt Diebner, [ Kurt Diebner, throughout the life of the nuclear energy project, had more control over nuclear fission research than did Walther Bothe, Klaus Clusius, Otto Hahn, Paul Harteck, or Werner Heisenberg. See Walker, 1993, 208.] Schumann, during this period, was one of the most powerful and influential physicists in Germany. [ Walker, 1993, 208.] [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann. Also see the entry for the KWIP in Appendix A and the entry for the HWA in Appendix B.]

When it was apparent that the nuclear energy project would not make a decisive contribution to ending the war effort in the near term by producing a nuclear weapon, the HWA had decided by January 1942 to relinquish its control of the nuclear energy project and leave it in the realm of research through the RFR. Even then, Schumann helped the project dodge what would have been a major blow to the project. Many scientists in the "Uranverein" working on the "Uranmaschine" (uranium machine, i.e., nuclear reactor) had the classification of "unabkömmlich" ("uk", indispensable) and were exempt from being drafted into armed service. Both Paul Harteck and Carl Friedrich von Weizsäcker had the classification "uk". However, as the war raged on, the demand for men to provide armed service they were both called up in January 1942 for service at the Russian front. Paul O. Müller and Karl-Heinz Höcker, colleagues of von Weizsäcker within the "Uranverein" had already been called up; Müller was killed on the Russian front. Werner Heisenberg, with the help of Schuman and Karl-Friedrich Bonhoeffer, who’s brother-in-law Hans von Dohnanyi held an influential position in the German army, managed to maintain the "uk" status for Harteck and von Weizsäcker and keep them working on the nuclear energy project. [ Walker, 1993, 42-43, 47, 49-53.] [ Hentschel and Hentschel, 1996; see the entry for the KWIP in Appendix A and the entry for the HWA in Appendix B.]

Post World War II

In German scientific community apologia after the war, the military’s Schumann and Diebner led aspects of the "Uranverein" were minimized, ridiculed, and ascribed to "Nichtkönnen" (incompetent scientists) and leadership that owed its positions to politics. Additionally, the Heisenberg component of the project was made to appear as the leading and dominant element of the project. Some of these same distortions came from Samuel Goudsmit. During the war, Goudsmit had been the chief scientist of Operation Alsos, under which Heisenberg had been arrested at the close of the war and incarcerated with nine other German scientists in England under Operation Epsilon. The motivations of the German scientists were to distance themselves from the military aspects of the "Uranverein" and, in the denazification environment, also distance themselves from those who had visible positions under National Socialism. Goudsmit’s motivations were, in part, political. He thought that the worship of German science was a detriment to the advancement of American science. [ Walker, 1993, 203-221.] [ Klaus Hentschel "The Mental Aftermath: The Mentality of German Physicists 1945 – 1949" (Oxford, 2007).] [ Heisenberg, Werner "Research in Germany on the Technical Applications of Atomic Energy", "Nature" Volume 160, Number 4059, 211-215 (August 16, 1947). See also the annotated version: "Document 115. Werner Heisenberg: Research in Germany on the Technical Application of Atomic Energy [August 16, 1947] " in Hentschel, Klaus (editor) and Ann M. Hentschel (editorial assistant and translator) "Physics and National Socialism: An Anthology of Primary Sources" (Birkhäuser, 1996) 361-397. These are slightly abridged translations of the following paper: Werner Heisenberg "Über die Arbeiten zur technischen Ausnutzung der Atomkernenergie in Deustchaland", "Die Naturwissenschaften" Volume 33, 325-329 (1946). [A preliminary draft of this Heisenberg paper, which differs significantly with the published version, survived and has been used by the historian Mark Walker in his analysis of the Goudsmit/Heisenberg controversy; see Walker, 1993, 205-221.] ]

In addition to Goudsmit’s magnification and distortions of Heisenberg’s role in the "Uranverein", Goudsmit ridiculed Schumann’s startup of the "Uranverein", the military testing station under Schumann’s purview, and Schumann himself:

*Goudsmit states Schumann and Diebner “in 1939, started secret atom bomb research for the German army, without the knowledge of reputable German nuclear scientists.” [ Goudsmit, Samuel "Alsos" (Tomash, second printing, 1986) p. 142.] This is clearly not true. Military control of the "Uranverein" under the HWA began on 1 September 1939, the day World War II began, and it had its first meeting on 16 September 1939. The meeting was organized by Kurt Diebner, advisor to the HWA. The invitees included Walther Bothe, Siegfried Flügge, Hans Geiger, Otto Hahn, Paul Harteck, Gerhard Hoffmann, Josef Mattauch, and Georg Stetter. A second meeting was held soon thereafter and included Klaus Clusius, Robert Döpel, Werner Heisenberg, and Carl Friedrich von Weizsäcker. This is an impressive list of talent in physics, including nuclear physicists of the day. [ Hentschel and Hentschel, 1996, 363-364 (especially footnotes #14, #15, and #16 on p. 354) and Appendix F; see the entries for Diebner and Döpel. See also the entry fro the KWIP in Appendix A and the entry for the HWA in Appendix B.] [ Macrakis, 1993, 164-169.] [ Jagdish Mehra and Helmut Rechenberg "The Historical Development of Quantum Theory. Volume 6. The Completion of Quantum Mechanics 1926-1941. Part 2. The Conceptual Completion and Extension of Quantum Mechanics 1932-1941. Epilogue: Aspects of the Further Development of Quantum Theory 1942-1999." (Springer, 2001) pp. 1010-1011.]

*A picture in one of Goudsmit’s articles [ Samuel A. Goudsmit "Nazis’ Atomic Secrets. The Chief of a Top-Secret U.S. Wartime Mission Tells How and Why German Science Failed in the International Race to Produce the Bomb", "Life" Volume23, 123-134 (October 20, 1947).

Hentschel (editorial assistant and translator) "Physics and National Socialism: An Anthology of Primary Sources" (Birkhäuser, 1996) 379-392. See the photograph annotated as Figure 28 and footnote #13, both on p. 383.] portrayed a small wooden shack as an atomic laboratory at the army proving grounds outside of Berlin. While it is not clear where the shack was located, the HWA "Versuchsstelle" in Gottow employed 125 personnel, clearly not possible in the shack.

*Goudsmit referred to Schumann as a “second-rate physicist” [ Samuel A. Goudsmit "War Physics in Germany", "The Review of Scientific Instruments", Volume 17, Number 1, Announcements, 49-52 (January 1946). Also see an annotated reprint, Document 111 "Samuel A. Goudsmit: War Physics in Germany [January 1946] " in Hentschel, Klaus (editor) and Ann M. Hentschel (editorial assistant and translator) "Physics and National Socialism: An Anthology of Primary Sources" (Birkhäuser, 1996) 345-352.] and a “mediocre physicst.” [ Goudsmit, Samuel "Alsos" (Tomash, second printing, 1986) p. 142.] That this was not the case is suggested by the fact that members of Schumann’s Habilitation committee for experimental and theoretical physics at the University of Berlin included the eminent scientists Max von Laue, Walther Nernst, and Max Planck, and the Habilitation was well before Hitler came to power. [ Macrakis, 1993, 79.]

After the war, Schumann wrote a book to get out his view of the German nuclear energy project, but publication was blocked by the British occupation authorities. Telling of some of the story from this perspective would have to wait until his right-hand man in the HWA, Kurt Diebner, published his book [ Dieter Bagge, Kurt Diebner, and Kenneth Jay "Von der Uranspaltung bis Calder Hall" (Rowohlt Taschenbuch Verlag, 1957)] in 1957. [ Walker, 1993, 206.]

Again from 1951, Schumann was director of the Helmholtz Institute of Sound Psychology and Medical Acoustics in Berlin. [ Hentschel and Hentschel, 1996, Appendix F; see the entry for Schumann.] He died in Homberg-Hülsa.
