From Heinrich Meng Stuttgart, 24 October 1928 Would like to discuss Sigmund Freud’s Nobel Prize nomination on 11 or 12 November in Berlin. TLS. [32 520]. 715. From David Hilbert Göttingen, 25 October 1928 Does not share AE’s opinion on Brouwer expressed in Doc. 291. It is fortunate for Math- ematische Annalen to be rid of Brouwer as a member of the editorial board. Attaches a copy of his letter to Brouwer ([13 144]) in which he dismissed him. TLS. [13 143]. 716. From Curt Schwarz Charlottenburg, 25 October 1928 Has realized that he was impertinent during yesterday’s meeting, while AE was only try- ing to be forgiving and supportive. ALS. [48 455]. 717. From Chr. Zaycoff Charlottenburg, 25 October 1928 Thanks for Abs. 710. Has learned from his mother that all the professors support Raschko. ALS. [24 202]. 718. From Raschko Zaycoff Sofia, 25 October 1928 Has received AE’s letter of 8 October (nonextant). G. Maneff succeeded in dismissing him. Happy with AE’s reading his book. Asks to present it to the Prussian Academy. Complains about AE dropping the fifth dimension. In his five-dimensional theory, the laws of quantum mechanics are causal. Cannot understand why AE accepted a position that is harmful to relativity. In its present form, AE’s theory of relativity can be made compatible with quantum theory only superficially. Asks why AE is critical of his work. ALS. [24 203]. 719. To Hans Delbrück [Berlin,] 26 October 1928 Asks whether Delbrück is acquainted with Hans Kantorowicz and, if so, whether he con- siders him mentally sound (see Abs. 693). TLS. [78 128]. 720. To Paul Plaut Berlin, 26 October 1928 In reply to Abs. 712, sends addendum to questionnaire (see Doc. 293). TLS. [97 475]. 721. To Erwin Schrödinger Berlin, 26 October 1928 Sorry for C. Schwarz’s harsh attack on Schrödinger. Suspects he has a brilliant vein. Sends him the address of the Lincoln-Stiftung. TLS. [73 455]. 722. To Albert Thomas [Berlin,] 26 October 1928 Has earlier intervened for a permanent position for L. Steinig at the Labour Office (Vol. 14, Abs. 645). Now has heard of seventeen new positions created there. Steinig has mastered four languages and worked as interpreter at conferences. Proposes him be- cause Steinig performs research in reduced circumstances. Professors E. Milhaud and W. Rappard at the University of Geneva can provide details. TLC. [48 505]. 723. From I. G. Haddad Beirut, 26 October 1928 Requests permission to translate Einstein 1917a into Arabic from its French translation. TLS. [46 550]. 724. From Herbert Handrek Kahla, 26 October 1928 As a remark to Einstein 1928b, 1928n, and 1928o, argues that it is not possible to have Riemann geometry with teleparallelism different from the Euclidean. ALS. [46 588]. 725. From Hans Delbrück Berlin, 27 October 1928 In reply to Abs. 719, informs that indeed Hans Kantorowicz is not normal. The only way to get rid of him is not to reply to his letters. TLC. [78 129]. 726. From Leopold Courvoisier [Berlin,] 28 October 1928 Thanks for the old letter by B. H. Wade (see Wade to Einstein, 30 July 1926, Vol. 15, Abs. 555). Years ago was also engaged in measuring the distance between Paris and Washington in connection with handling of telegraphic time signals between the United
