1918réf. 135751918. Mathematics Klein Felix. Autograph Letter Signed 10 November 1918 written in German to a former student and colleague directly references Einstein's recently published General Theory of Relativity and comments on the work of the International Mathematical Education Commission. Composed in the closing days of the First World War the letter places Klein within active scholarly exchange concerning the mathematical implications of relativity which had been formally presented in 1915 and widely disseminated by 1918. Klein long established for his foundational contributions to group theory non-Euclidean geometry and mathematical physics addresses questions raised by "Einstein's theory" noting that he required further reflection to clarify its implications for his own work. The document supports research in the history of relativity German mathematical networks scientific communication during wartime and the institutional organization of mathematics in the early twentieth century. Klein Felix. Autograph Letter Signed 10 November 1918. Two pages written on both sides of a single leaf. In German with accompanying English translation. Addressed to a former student the letter discusses the circulation of lecture manuscripts difficulties in securing copyists during wartime conditions and the intellectual demands posed by Einstein's theory: "A further exploration of my work does not exist yet as I had and still have more thinking to do about questions raised by Einstein's theory to clarify it for myself." Klein also comments critically on the IMUK observing that its published statements are "a display of wasted paper" while acknowledging the commission's broader social significance. He singles out contemporary educational treatises including studies by W. Trost Heinrich Emil Timerding and M. Girndt indicating his sustained engagement with mathematical pedagogy alongside theoretical research. The letter was written days before the November Revolution in Germany and at a moment when academic institutions faced political upheaval and material shortages. Klein's remarks regarding limited copyists and uncertainty about the coming months provide contemporaneous evidence of scholarly life under strained postwar conditions. His reference to Einstein situates the correspondence within the earliest phase of professional reception of general relativity among leading mathematicians while his comments on the International Mathematical Education Commission underscore his longstanding commitment to mathematical instruction and institutional reform. Clean and well preserved with strong legibility and a clear signature. Overall near fine condition. A substantive document of early relativity discourse and mathematical research at the end of the First World War. unknown
1954réf. 195551954. in German black ink. Signed “A. Einstein”. A poem written by Einstein to his colleague and collaborator Ernst Straus and his son Daniel. “Dear Strausse both! My best wishes and greetings in poetic form. It brings even more happiness If it has been anticipated for so long also in one’s circle of friends the event is doubly appreciated. This is what I wish: Let Daniel be like his father thoroughly intelligent and not less joyous so few humans are like that. Many - alas - are born few are chosen to bring light and joy. Let such gift be his drive. Yours A. Einstein” In German “Strauss” means bunch bouquet etc. or ostrich and “Strausse” is plural. Ernst G. Straus 1922-1983 was a mathematician who helped found the theories of Euclidean Ramsey theory and of the arithmetic properties of analytic functions. He was Einstein’s assistant and collaborator both at Princeton and afterwards when he moved to become a professor of mathematics at UCLA. His son Daniel is a professor of chemistry at Cal State San Jose. unknown

1912réf. 29311Leipzig Barth 1912. 8vo. Orig. printed wrappers. Backstrip taped. Kept in a cloth-box. In: "Annalen der Physik IV Bd. 38" pp. 355-369 and pp. 443-458. The whole issue present= Bd. 38 Heft 2 pp.249-472. Both papers in first edition and they are considered as the first appearance of a Nonlinear Field Equation for Gravitation. - "Einstein published two remarkable memoirs in 1912 which were efforts to construct a complete theory of gravitation incorporating the equivalence principle. In these memoirs Einstein supposed that the gravitational field can be characterized completely by one function the local speed of light analogous to the Newtonian description where only the gravitational potential appears. By an extraordinary argument he extended the potential equation of Newton.In his second Memoir in 1912 he used the equivalence principle to show the influence of a static gravitational field on electromagnetic and thermal processes."
