C A L E N D A R O F A B S T R A C T S O C T O B E R 1 9 2 8 8 6 7 684. From Heinrich Zangger [Zurich,] 11 October 1928 Having met with L. Lichtwitz and W. Löffler, discussed AE’s condition with them and shared the opinion that AE should keep calm for a longer time in order to recover fully. TLS. [97 137]. 685. From Gaetano Castelfranchi Milan, 12 October 1928 Sends his popular book Castelfranchi 1929, which contains an elementary exposition of parts of AE’s work for nonspecialists. ALS. [74 400]. 686. From Horace M. Kallen [New York,] 12 October 1928 He has requested that the publishers send proofs of letters on Sacco and Vanzetti. To- gether with J. Dewey, is setting up an international committee to sponsor the publication. Invites AE, together with R. Rolland, G. Santayana, H. Bergson, M. Gorky, G. B. Shaw, S. Zweig, J. Galsworthy, B. Russell, and B. Croce to join the sponsors. TLC. [75 444]. 687. From Reinhold Köbke Berlin, 12 October 1928 As follow up to Abs. 666, his invention makes use of hydroxygen produced by self- sustaining electrolysis. The gas would lift cups on a closed chain lifting weight, and when the cups move downward, the gas from them could be used for fuel. Gives calcu- lations for the work invested and gained. ALS. [25 131]. 688. From Reinhold Köbke Berlin, 13 October 1928 Corrects calculations in Abs. 687. The Ministry of the Interior, the Academy of Sciences, and the KW Institute of Electrochemistry refused financing or testing the invention. Asks help in finding someone willing to invest 5,000–10,000 M. ALS. [25 132]. 689. From Max Lagally Dresden, 13 October 1928 In reply to Abs. 682, informs that R. Lützner began his university studies because he was interested in learning. That now he aspires to a higher degree is due to the success of some of his colleagues in doing it. His abilities do not exceed those of average students. He is not the only one who wants to be an exception under the restrictive rules of the ministry. Does not think his case is worthy of AE using his influence. TLS. [47 563]. 690. From Paul Vogel (Gefion-Verlag) Berlin, 13 October 1928 Sends the first volume of Illustrierte Weltgeschichte. The press’s aim is to publish high- quality books at affordable prices for people of moderate income. To make this possible, it should publish them in a large edition. If AE considers the price of 3.80 M serves a purpose, asks for a written opinion with which the press would launch the enterprise. TLS. [46 355]. 691. To Reinhold Köbke [Berlin,] 15 October 1928 In reply to Abs. 687 and 688, explains that the invention is based on incorrect presuppo- sitions. The apparatus would work as a perpetuum mobile, which he hopes Köbke also considers impossible. TLC. [25 134]. 692. To Richard Lützner [Berlin,] 15 October 1928 In reply to Abs. 675 and 681, informs that he is unable to give him such a large loan from personal funds. The difficulty in Lützner’s case is that many others are in the same situation. The government considers the case a question of principle over which AE has no influence. Would intervene only if Lützner could show extraordinary scientific achievements. TLC. [47 564]. 693. From Hans Adolph Kantorowicz Charlottenburg, 15 October 1928 Sends summary and complaints about his recent conversation in AE’s home, where he requested financial and moral help to publish his investigations regarding the guilt of the Entente in World War I and also broached the subject of Jewish Christians.
