Urey s theory was closely related to an earlier theory of the formation of the planets proposed by the German physical chemist Arnold Eucken in 1944. [97] However,... 

Polanyi, The potential theory of adsorption," 1013, n. 2. Polanyi noted that Arnold T. Eucken had introduced the term Ad-sorptionspotential in 1914, a few months before Polanyi s first paper on the subject. 

Der Chemie-Ingenieur was far more imposing, an encyclopedia about physical operations in chemical and related process industries. It totaled 12 volumes published between 1932 and 1940 under the editorship of Professor Arnold Eucken of Gottingen and, initially, Professor Max Jakob of Berlin, who soon departed for the United States. Figure 10 shows the encyclopedia, with Perry s Handbook in front. Eight volumes treat unit operations on a scientific footing, with abundant citations of sources, frequent use of mathematical tools, and sophisticated accounts of the best practice. Then came the add-on volumes, which treated physicochemical and economic aspects of chemical reaction operations, i.e., chemical process principles ...

For my research activities I have received various aw ards. e.g. the Arnold-Eucken Prize in 1982 from GVC (Gesellschaft fiir Verfahrenstechnik und Chernieingenieurwe-sen), the Rossini Lecture Award 2008 from the International Association of Chemical Thermodynamics and 2010 the Gmelin-Beilstein Denkmunze from GDCh (Gesellschaft Deutscher Chemiker). 

Karl Friedrich Bonhoeffer and Arnold Eucken, met similar resistance. The Ministry of Education and the Ministry of Defense wanted application-oriented, military research to continue at the Institute until an appropriate military institute could be established. Hence, as far as the two Ministries were concerned, Thiessen was a far more suitable Director than the lauded scientists proposed by the KWG. While this debate unfolded between the ministries and the KWG, Thiessen was promoted to an academic post adequate for a KWG director. After he had failed to find a position in Freiburg or Frankfurt, Thiessen was offered the post of Professor of Chemistry and Director of the Chemistry Institute at Munster in March of 1935, succeeding Rudolf Schenck. Though his appointment was confirmed by the Ministry of Education on 1 April 1935, Thiessen never occupied the post. On 20 May 1935 the Ministry of Education named Thiessen Director of the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry, as well as Professor for Physical Chemistry at Friedrich Wilhelm University in Berlin. In the minutes of the Institute s board meeting a month later, Planck noted that the naming of the new Institute Director had come about in an unusual manner nevertheless, he accepted the political imposition and expressed his desire to work together with Thiessen.
