Einstein, Mar. 28, 1918, family trust correspondence: “The postcard you sent to my mother was really not nice . . . Her words would not
have offended you in any way if you had heard them yourself; you would just have laughed and would have toned down their sense a little.”
41. Mileva Mari to Einstein, Mar. 17, 1918: “My state of health is now such that I can lie down quite well at home; although I can’t get up, I can
very well occupy myself quite a considerable amount with the children, and this makes me very happy and contributes much to my wellbeing.”

51. Born 2005, 145–147. My description relies on Born’s recollection, which accompanies Einstein’s references to the event in a letter to
Born, Sept. 7, 1944. See also Bolles, 3–11; Seelig 1956a, 178; Fölsing, 423; Levenson, 198.
52. Einstein, “On the Need for a National Assembly,” Nov. 13, 1918, CPAE 8: 14; Nathan and Norden, 25. Otto Nathan says that Einstein
delivered these remarks to the student radicals at the university. There is no evidence of this, and Born does not mention it. The
newspapers report it as a New Fatherland League speech later that day. See CPAE 8: 14 (German edition), footnote 2.

to Einstein, Jan. 28, 1919. Vetter was the president of Zurich University, and he responded to Einstein’s complaint about a guard being

Time and Gravitation: An Outline of the General Relativity Theory (Cambridge, England: Cambridge Science Classics, 1995). Page

and is translated in many ways. The German sentence, as recorded by Rosenthal-Schnieder, is “Da könnt’ mir halt der Liebe Gott leid tun,
