From Richard Audorf Hamburg, 3 October 1927 As an amateur scientist, believes that Galileo’s law of inertia needs to be modified and has new views on gravitation and inertia. TLS. [45 447]. 171. From Hans Albert Einstein Dortmund, 3 October 1927 Has followed AE’s advice expressed in Abs. 150. Requests advice in his patent case. ALS. [144 055], [144 056]. 172. From Georges Oprescu Geneva, 3 October 1927 The Comité de Direction of the IIIC will meet in Paris on 2 November 1927 at 10 A.M. TLS. [84 643]. 173. From the Solvay Institute for Physics Brussels, 3 October 1927 Acknowledge AE’s promise to H. A. Lorentz to participate in the Fifth Solvay Confer- ence, 24–29 October 1927. Participants will stay in Hotel Britannique. Lorentz has al- ready informed him of the program and the topics of reports. They will be published in French. TLC. [83 404]. 174. From Ludwig Baumgardt Berlin, 4 October 1927 Sends newspaper article on Kurd Lasswitz, whom he was close to for many years. Draws attention to Lasswitz’s estimate of the size of the universe based on non- Euclidean geometry. Informs that after studying engineering in Darmstadt 1883–1887 and being an assistant to Franz Himstedt, he had been director of Einstein & Co. in Munich 1890–1891 and inquires whether AE is related to the two brothers who owned the factory. ALS. [45 494]. 175. From Felix Danziger Jerusalem, 4 October 1927 Following up on a request by Arthur Felix (see Abs. 128), details his experience over the past years with appointments and policies pertaining to medical and biological re- search at the Hebrew University. Was initially disappointed that American Zionists rejected his proposal for a medical faculty. The establishment of a microbiological insti- tute became contentious. The Anglicization of the entire administration of the university had negative effects, as well as the overbearing influence of Hadassah Hospital. Kligler has an outsize influence in all matters. A. Felix and Sophia Getzowa are being silenced. TLS. [36 969]. 176. From Ayao Kuwaki Berlin, 4 October 1927 Having just recently returned to Berlin, in reply to Abs. 123, wishes to visit on Friday 7 October in the afternoon. ALS. [47 333]. 177.

To Richard Audorf Berlin, 5 October 1927 In reply to Abs. 170, finds that Audorf has not devoted the necessary careful consider- ation to his treatment of the issues. TLC. [45 448]. 179. To Max Bergmann Berlin, 5 October 1927 Appreciates Bergmann’s intellectual energy, but his results could not be taken seriously by specialists. Bergmann could have been an eminent theoretician had he acquired the necessary knowledge of physics and mathematics. Asks questions of Bergmann’s cir- cumstances to be able to help him find a sphere of activity. TLC. [45 576]. 180. To Hugo A. Krüss Berlin, 5 October 1927 Proposes a conversation on matters related to the ICIC and the IIIC, since it appears that significant discrepancies seemed to become evident at the July meetings between the aims and actions of the Institute and the intentions of the Commission.
