D O C U M E N T S 9 0 , 9 1 M A R C H 1 9 2 2 1 9 1 [Vol. 7, Doc. 38]). The article also alleged that Hirschfeld had subsequently given the manuscript, in return for 500 marks, to his son Kurt who ran a “wild” autograph business and in turn sold it for 3,000 marks to an antiquarian. The antiquarian then sold the manuscript for 5,000 marks. The publication decried the fact that Hirschfeld’s son, rather than the needy students, had profited from the donation (see Die Welt am Montag, 13 March 1922, Beilage). In his letter to Einstein, Hirschfeld assumed that the article had appeared on Einstein’s behalf (“auf Ihre Veranlassung”) and claimed that he and his son were innocent. His letter included a copy of a “correction” (“Berichtigung”) sent for publication to the Welt am Montag, in which it was claimed that his son had only received 600 marks for the man- uscript, of which he had deducted 100 marks to cover his own expenses (see Max Hirschfeld to the editors of Welt am Montag, 14 March 1922 [43 906]). 90. To Paul Winteler and Maja Winteler-Einstein [Berlin,] 17. III. 22 Lieber Pauli und liebe Schwester! Mit Bestürzung habe ich aus der Karte entnommen […] Ich gehe, am 28. III nach Paris, um am Collège de France einige Vorlesungen zu halten und im Herbst nach Japan und China. Vielleicht nehme ich Else mit. ATrL. [81 472]. Partial transcript in Pierre Speziali’s hand. Probably a reference to the news that Maja underwent two operations as a result of a boil on the back of her head (see Doc. 83). 91. To Arnold Berliner [Berlin, on or after 17 March 1922] Lieber Herr Berliner. Ich bin so fest eingespannt, daß ich garnicht daran denken kann, den gewünsch- ten Bericht zu schreiben. Dagegen hoffe ich, die Zeit zu erübrigen, den Warburg- Artikel bald fertig zu stellen. Ihre Absicht, Thirring oder Kopff mit der Abfassung des Berichtes zu beauftragen, billige ich durchaus. ADft. [7 012.1]. Written at the end of Abs. 114 in Ilse Einstein’s hand. Dated by the fact that it is a response to Abs. 114. Arnold Berliner (1862–1942) had asked Einstein to contribute a review of relativity theory for a new companion series to the weekly Die Naturwissenschaften, which Berliner was to edit under the title Ergebnisse der exakten Naturwissenschaften. According to Berliner, Einstein had previously expressed himself “not entirely opposed” (“nicht ganz abgeneigt”) to the idea (see Abs. 114). See Einstein 1922l (Doc. 231). Hans Thirring August Kopff (1882–1960) was Extraordinary Professor of Astronomy at the University of Heidelberg. The second contribution in the first volume of the Ergebnisse is Thirring 1922b.
