C A L E N D A R O F A B S T R A C T S J A N U A R Y 1 9 2 9 8 8 3 854. From Arnold Berliner Berlin, 26 January 1929 Objects vociferously to the treatment of Erwin F. Freundlich at the hands of Hans Ludendorff at the last board meeting of the Einstein Tower. Emil Rathenau, who was irascible, but a brilliant man, would never have been insulting or accused Berliner of hair-splitting in public. Moreover, objects that Ludendorff insists on taking personal credit for collaborative work. He will send copies of this letter to the representative of the education ministry, E. Leist, and to M. von Laue, and requests that his letter be made part of the official board documents. TLS. [11 301]. 855. From Harold A. Malpas Bristol, 26 January 1929 Proposes to discuss his discovery of “biblical” proportions related to radioactivity. TLS. [47 587]. 856.

From Robert Emden Munich, 28 January 1929 Thanks for reviewing his paper on aberration and the comments sent to A. Sommerfeld. One statement to which AE objected was in fact Emden’s critique of an opponent of rel- ativity. In view of recent discussions, his purpose with the paper was to show that aber- ration can be completely explained by the theory of relativity. ALS. [9 255]. 858. From Georgi I. Maneff Sofia, 28 January 1929 Solicits AE’s opinion on his manuscript on the Schwarzschild equation in general rela- tivity. Asks not to take it as a critique of the theory. ALS. [17 052]. 859.
