From Emil Gumbel Heidelberg, 30 April 1926 Has returned from a six-month visit to Moscow, where he prepared Marx’s so-called mathematical manuscripts for the press. They are notes to differential calculus that have some philosophical interest. Most scholars there are in a dire situation. Thanks for AE’s intervention with Julius Schaxel (Abs. 95). Intends to restart his lectures in Heidelberg, against much opposition. The Social Democrat minister of education Adam Remmele and the university are determined to terminate him, but he will not cave in. TLS. [43 814]. 441. From Frederick Kuh Berlin, 30 April 1926 Requests AE’s comment on a talk given by D. C. Miller at the National Academy of Sci- ences in Washington, D.C., on 26 April, in which he refuted AE’s statements that all mo- tion is relative rather than absolute, and that the ether does not exist based on his recent experiments at Mount Wilson. United Press would distribute the comment to thousands of newspapers. TLS. [17 271]. 442. From Johannes Trieglaff Berlin, 1 May 1926 Sends condolences on the death of Rudolf Einstein. Elsa Einstein requested the follow- ing information from him: He began work in the clinic of Dr. Bier in 1912 in the nephrol- ogy section. He was a decorated volunteer in the war. His patent is not yet ready. ALS. [45 128]. 443. From Samuel Braun Beregszász (Czechoslovakia), 3 May 1926 Sends his modest booklet and requests a recommendation or foreword.

From Deutsche Liga für Menschenrechte (Konrad Ziffer) Berlin, 3 May 1926 Received AE’s letter of 22 March and Rudolf A. Senftle’s letter and, as per its letter of 26 March, has pursued the matter.

From Robert Eisler Paris, 3 May 1926 Thanks for AE’s kind letter and for his intervention with Alfred Przibram (see Abs. 426). Is rather depressed, but happy to report that he will lecture at the Institut de France, Académie des inscriptions et belles lettres, on the Josephus text, on a later and not well understood description of the actual historical Jesus (“medium, bent figure, long face, long nose, eyebrows grown together, so that people who saw him would be scared, little hair, in the middle of the forehead a multiplication sign as customary with the Naza- renes”). This is the most significant discovery that could have been made in this field. ALS. [43 622]. 446.
