DOCUMENT 445 JUNE 1913 529 ADS in the hand of Max Planck (GyBAW, II-III, Vol. 36, pp. 36-37). Kirsten and Treder 1979, pp. 95-97. [71 187]. The text of the proposal was read aloud to the physical-mathematical class of the Prussian Academy of Sciences on 12 June by Max Planck (see the minutes of the meeting of the class, GyBAW, II-V, Vol. 132, item 2), the presiding secretary of the class. Two weeks earlier Planck, Emil Warburg, Heinrich Rubens, and Walther Nernst had announced in the physical-mathemat- ical class that they would submit a proposal for membership at the next session. The identity of the candidate is not given (see memorandum of Max Planck et al., 29 May 1913, GyBAW, II-III, Vol. 36, p. 35, and the minutes of the meeting of the class, of the same date, GyBAW, II-V, Vol. 132, item 5). At the beginning of the year Fritz Haber had proposed that Einstein be brought to Berlin as a member of his Kaiser Wilhelm Institute of Physical Chemistry and Electrochemistry, and Planck is singled out for a key role in implementing the plan (see Doc. 428). Between January and May 1913, however, the emphasis seems to have shifted. By late spring Planck and Nernst had modified Haber's proposal, combining the idea of Einstein's membership in the Academy with the prospect of his directorship of a Kaiser Wilhelm Institute of Physics, though the ques- tion of an institute remained unresolved until Einstein's arrival in Berlin in spring 1914 (see Doc. 482). For a discussion of the divergent interests of the Prussian Academy and the Kaiser Wilhelm Society against the backdrop of which the proposal modifications may have taken place, see Wendel 1964, pp. 134-145. Walther Nernst took the occasion of the class meeting of 12 June to make a confidential announcement that Einstein's salary might be raised to 12,000 marks because of a personal commitment by Leopold Koppel to provide 6000 marks a year for a twelve-year period (see the minutes of the meeting of the class, and Leopold Koppel to Walther Nernst, 3 June 1913, enclosed in Leopold Koppel to Max Planck, 28 January 1914, GyBAW, II-III, Vol. 36, pp. 73- 75). Koppel had already expressed his willingness to help defray the costs of an appointment for Einstein at the beginning of the year (see Doc. 428). Einstein published six papers (and a number of reviews) before completing his disserta- tion (see Vol. 2, Docs. 1-5, 14). Of the papers cited in note 3, only Vol. 2, Doc. 1, is dated from Zurich the others are dated from Bern. Einstein 1905j (Vol. 2, Doc. 15) was the dissertation. The venia docendi was conferred upon Einstein by the Philosophical Faculty of the Uni- versity of Bern on 28 February 1908 (see Doc. 89). Einstein was appointed Extraordinary Professor of Physics on 7 May 1909, effective 15 October 1909 (see Doc. 154, note 2). On 6 January 1911 he was appointed Professor of Theoretical Physics at the University of Prague, effective 1 April 1911 (see Doc. 245). He was appointed Professor of Theoretical Physics at the ETH on 30 January 1912, ef- fective 1 October 1912 (see Doc. 355). An inquiry from Friedrich Schmidt(-Ott) of the Prussian Ministry of Education on 16 June regarding Einstein's personal and academic background elicited ETH President Robert Gnehm's expression of regret at the prospect of losing such a "brilliant scientist" ("genialen Forscher") (see Alfred de Claparede, Swiss Legation in Berlin, to Robert Gnehm, Präsident, Swiss School Council, 16 June 1913, SzZE Schulratsarchiv 1913, Akten, no. 624, and Robert Gnehm to Alfred de Claparede, 18 June 1913, SzZE Schulratsarchiv 1913, Missiven I, p. 268). Two days later the Swiss envoy in Berlin made a report on Einstein's personal and academic background to the Ministry (see Alfred de Claparede to Friedrich Schmidt, Ministerial-Direk- tor, 20 June 1913, GyMerSa, Rep. 76 Vc, Sekt. 2, Tit. 23, Litt. F, Nr. 2, Vol. 14, pp. 88-89). Einstein 1905r (Vol. 2, Doc. 23). Einstein had met separately with the four signatories on a visit to Berlin a year earlier (see Docs. 377 and 389, note 5).
