3 6 8 D O C U M E N T 2 2 4 J U N E 1 9 2 8 Albert ist mit seiner Frau bei uns zu Besuch.[6] Er ist glücklich mit ihr und sieht gut aus. Ein Kind ist gottlob nicht im Anzug.[7] Also ist kein Grund zum Jammern. Jedem Tierchen sein Pläsierchen. Das Engadin und Bezzolas Behandlung haben Ilse gut gethan.[8] Sie ist zwar nach wie vor leidend, aber der Lebensmut ist ge- wachsen. Ich habe in der Ruhe der Krankheit ein wundervolles Ei gelegt auf dem Gebiete der allgemeinen Relativität.[9] Ob der daraus schlüpfende Vogel vital und langlebig sein wird, liegt noch im Schosse der Götter. Einstweilen segne ich die Krankheit, die mich so begnadet hat. Danke Ihnen, dass Sie für die E. v. Schneider eingetreten sind.[10] Die Arme verdient es sie ist übrigens beständig in Gefahr völlig zu erblin- den. Ihr ganzes Streben ist die Erziehung ihres Sohnes, eines recht feinen und klu- gen Knaben, den sie von Nicolai hat.[11] Herzlich grüsst Sie Ihr A. Einstein. ALS (SzZuZB, Nachlass H. Zangger, box 1c). [86 530]. Schulmann 2012, pp. 469–471. Hans Albert’s appended greetings are omitted. [1] Dated by the fact that Hans Albert Einstein and Frieda Einstein-Knecht were visiting and that the letter was written around the time of Doc. 222. (Dated “before 10 July 1928” in Schulmann 2012, p. 469). [2] Zangger expressed his deep concern for Einstein’s heart condition when it was first diagnosed in late March (see Doc. 163). He may have also treated Einstein for his illness during a visit to Berlin. [3] At the end of March, Einstein had predicted that he would have to undergo a rest cure for several months (see Doc. 164). [4] János Plesch (1878–1957) was a prominent Hungarian-born German-Jewish internist, Extraor- dinary Professor for Internal Medicine at the University of Berlin, director of the Department of Inter- nal Medicine at the Franziskus Hospital in Berlin, and personal physician to many German celebrities. [5] Rudolf Ehrmann was a German-Jewish physician, Professor of Internal Medicine at the Univer- sity of Berlin, director of the Department of Internal Medicine at the Neukölln Hospital, and one of Einstein’s personal physicians. [6] Hans Albert Einstein and Frieda Einstein-Knecht. [7] Einstein had vehemently opposed the marriage of Hans Albert and Frieda for an extended period of time. One of his strongest objections to their relationship was his perception of Frieda’s alleged inferior genetic pedigree (see Vol. 15, Introduction, pp. liv–lvi). [8] Ilse Kayser-Einstein had been under the care of Dumeng Bezzola, a specialist in nervous disor- ders, at his clinic in Celerina for several months in the winter of 1927/28 (see Doc. 151). [9] A reference to the teleparallel approach see Einstein 1928n and 1928o (Docs. 216 and 219). [10] Elly von Schneider. Her son was Arne von Schneider-Glend. Zangger had written to Einstein about assisting in obtaining a visa for her and her five-year-old son to stay in Switzerland, presumably for medical care for Arne, who was suffering from tuberculosis. Schneider had given Einstein as a German reference (see Abs. 597 and Schulmann 2012, p. 466). [11] Georg F. Nicolai.
