Würden Sie anneh- men, wenn ich Sie durchsetze? Bitte antworten Sie recht schnell und sagen Sie ja, denn Sie dürfen einen kranken Mann wie mich nicht so schwer enttäuschen.— Es grüsst Sie herzlich Ihr TLC. [46 401]. Addressed “Herrn Dipl. Ing. Wichard v. Moellendorf Schlachtensee Friedr. Wilhelm- str. 17/19.” [1] Moellendorff (1881–1937) was a German engineer and economist, director of the Prussian Staatliches Materialprüfungsamt and of the KWI für Metallforschung and member of the senate of the KWG. [2] The International Labour Office was set up in 1919 in Geneva as the permanent secretariat of the International Labour Organisation (ILO). The Treaty of Versailles established the ILO in June 1919. Its goal was to urgently improve the conditions of labor that involved “such injustice, hardship, and privation to large numbers of people as to produce unrest so great that the peace and harmony of the world are imperilled.” The functions of the International Labour Office included preparing “the agenda of [International Labour] Conference and the carrying out of its decisions” and “the collection and distribution of information on all subjects relating to the international adjustment of conditions of industrial life and labour” (see Barnes 1926, pp. 77, 81, 85–86, and ILO 1926, p. 30).

[22. 4. 28.][2] Dear Professor Einstein You will, I think, be interested to hear that, after many delays, the collected edi- tion of Hamilton’s works has at length been definitely undertaken by the Royal Irish Academy.[3] My brother and another[4] are at present engaged on the prepara- tion of the first volume,[5] which will, I understand, comprise the Essays on Rays, and be followed by other volumes. It was not at all an easy matter to get the project through![6] I hardly know whether what I am enclosing may interest you. It is the outline of a method which has occurred to me, and which combines the principles of the ultra- microscope with the method of holding up a picture employed in telephotography, and seems to promise results of no small practical importance, especially in con- nection with medical discovery. By means of this method the present theoretical limitation to the resolving power in microscopy seems to be completely removed and everything comes to depend upon technical perfection. I have consulted various people who are qualified to express an opinion either on the theoretical or the practical side, and they confirm my own view, that the method is theoretically sound, and that the practical difficulties—while formidable—are not
