From Rudolf Seeliger Hagen, Westfalia, 3 July 1927 In reply to Doc. 13, thanks for AE’s notes on his essay “Der Weg der Physik…” Accepts that theories are free creations of the mind but does not understand yet that no spatial relations and no order between sensory perceptions are given. The latter are for him the primordial elements of knowledge. TLS. [25 274]. 52. From Heinrich Zangger Zurich, 4 July 1927 Marcel Grossmann has entered retirement, with a diagnosis of multiple sclerosis, which Zangger finds correct. Grossmann will now be able to work peacefully the symptoms are not too depressing. He has discussed the matter with E. Grossmann, Marcel’s brother. Zangger himself has been unwell. TLS. [40 064]. 53. From Léon Lichtenstein Leipzig, 5 July 1927 In response to a (nonextant) letter from AE, is very unhappy with Sternberg’s minimal offer of support for A. Wintner. He has succeeded registering Wintner in Leipzig as a graduate student, so that he could complete his Ph.D., and will continue to act on his commitment to the promising young man. ALS. [47 442]. 54. From R. Herrnstadt (Reichsbund Jüdischer Frontsoldaten) Berlin, 6 July 1927 The association is organizing a charity event in behalf of unemployed comrades, rela- tives of the fallen, and orphans.

He cannot be absent from Berlin for an entire term as stipulated (see Abs. 50), and lecturing in English would be strenuous. He does not feel that he has sufficiently important new work to report on. TD. [97 340]. English translation of an un- available German original. 57. From Willy Reitsch Hirschberg [Jelenia Góra, Poland], 9 July 1927 Asks AE to test in his physics institute the theory of the violin maker Max Großmann, who over several decades has proved that the secret of the Cremonese violins lay not in any special materials but in the ability of the violin makers to tune the violins to perfect fifths. Wishes to make sure this is being recognized as a German achievement, rather than as that of others. TL. [48 102]. 58. From Felix Ehrenhaft Vienna, 11 July 1927 In reply to Abs. 29, proposes to postpone a lecture in Berlin to the fall. Rosenberg in- formed him earlier that he sees no reason to attract Hans Albert Einstein to Vienna, since he is being employed at such a good company in Dortmund. Mentions the request in Abs. 26. TLS. [10 380]. 59. From Julius Seelmann Aachen, 11 July 1927 Thanks for (nonextant) communication regarding the Lemann family. Although he has been supporting his niece Mrs. Lemann, he has sent an additional 300 M to Berlin. In- quires confidentially whether Mr. Lemann, age twenty-nine, is making any progress in his studies. TLS. [48 282]. 60. From James B. Baillie [Leeds,] 12 July 1927 Informs that the University of Leeds wishes to offer AE an honorary Doctor of Science degree at a ceremony to be held during the meeting of the British Association in Leeds in 1927 however, such degrees are not conferred in absentia. TLS. [30 225].
