[1] Kohn (1894–1961) was secretary of the BOGHU and of the Hebrew University’s Academic Council. [2] Dated by the reference to Selig Brodetsky’s report and that it was written in June 1927 (see note 7) and on the assumption that the reference to Judah L. Magnes’s planned trip to the United States in August 1927 means that the letter was written prior to the beginning of August. [3] The Hebrew University’s Academic Council was envisaged at the second meeting of the BOGHU in Munich in September 1926. It would function as the university’s senate until that body had been established. Its goal was to provide the board with recommendations for the university’s aca- demic program and appointments. Einstein had been elected chairman of the Academic Council at the meeting in Munich and reelected at the board’s third meeting in London in August 1926 (see Einstein to Chaim Weizmann, 8 November 1926 [Vol. 15, Doc. 409]). [4] Louis Marshall (1856–1929) was an American lawyer, Jewish community leader, and president of the American Jewish Committee. Einstein met with him in Geneva on 27 July 1925 (see Einstein to Elsa Einstein, 28 July 1925 [Vol. 15, Doc. 35]). [5] Chaim Weizmann (1874–1952) was president of the Zionist Organisation. Einstein and Weizmann were the two members of the Hebrew University’s presiding committee. [6] Judah L. Magnes (1877–1948) was chancellor of the Hebrew University. [7] Selig Brodetsky (1888–1954) was a Russian-born British-Jewish mathematician and Professor of Applied Mathematics at the University of Leeds. As a member of the BOGHU, he had been asked to head a subcommittee to examine the issues of research, publications, and the introduction of under- graduate teaching at the Hebrew University (see Chaim Weizmann to Judah L. Magnes, 6 July 1927 in Weizmann 1978, p. 291, note 3). In his memoirs, he stated that he wrote the report in June 1927 (see Brodetsky 1960, p. 116). In the subcommittee’s report, the two proposals were formulated as fol- lows: “As at present constituted the Academic Council attached to the Board of Governors of the Uni- versity cannot function with the expedition that is sometimes desirable. […] The Committee considers that possibly two steps might be taken to remedy this state of affairs. The first would be the appointment of a small standing Academic Committee, which should meet often and be in constant touch with the Chancellor and the University Council. The second would be the strengthening of the University administration in Palestine on the academic side. For this a man of high academic status with intimate experience of University life and administration in Europe or America would be essential” (see “Report on Teaching and Research in and Publications by the Hebrew University of Jerusalem,” 1 September 1927, p. 19 [IL-RWW]). 2. From Werner Heisenberg[1] Kopenhagen 10. 6. 27. Sehr verehrter, lieber Herr Professor! Vielen herzlichen Dank für Ihren freundlichen Brief [2] obwohl ich eigentlich nichts neues weiss, möchte ich doch nocheinmal schreiben, warum ich glaube, dass der Indeterminismus, also die Ungültigkeit der strengen Kausalität, notwendig ist, nicht nur widerspruchsfrei möglich. Wenn ich Ihren Standpunkt richtig verstanden hab, dann meinen Sie, dass zwar alle Experimente so herauskommen würden, wie es die statistische Qu. M. verlange, dass es aber darüber hinaus später möglich sein werde, über bestimmte Bahnen eines Teilchens zu sprechen. Unter Teilchen mei- nen Sie dabei nicht etwa ein Wellenpaket nach Schrödinger,[3] sondern einen Ge-
