When Leonhard Euler first arrived at the Russian Academy of Sciences, at the age of 20, his career was supported and promoted by the Academy’s secretary, the Prussian jurist and amateur mathematician Christian Goldbach (1690-1764). Their encounter would grow into a lifelong friendship, as evinced by nearly 200 letters sent over 35 years. This exchange – Euler’s most substantial long-term correspondence – has now been edited for the first time with an English translation, ample commentary and documentary indices. These present an overview of 18th-century number theory, its sources and repercussions, many details of the protagonists’ biographies, and a wealth of insights into academic life in St. Petersburg and Berlin between 1725 and 1765. Part I includes an introduction and the original texts of the Euler-Goldbach letters, while Part II presents the English translations and documentary indices.

in die Analysis des Une n d I i chen. Von Leonhard Euler. Erster Teil. Ins Deutsche ubertragen \'Oll H. Maser. Springer-Verlag Berlin Heidelberg GmbH 1885. Vorwort des U ebersetzers. Meisterwerke uben ihren Einfluss auf die Fortbildung der Wissen- schaft nicht allein durch die in ihnen niedergelegten Resultate des forschenden Geil'ites, es lebt in ihnen eine schoepferische Kraft, die, nie er- sterbend, immer neue Keime weckt und fort und fort bis in die spate Ferne hinaus edle Fruchte zeitigt. Derartige Geistesproducte, wenn sie selten werden, in ihrer ganzen Fulle ohne Unterlass von Neuern weiteren Kreisen zuganglich zu machen, halte ich fiir kein nutzloses Beginnen. Eben dem Zwecke soll auch die Herausgabe der vorliegenden, ganzlich nenen Uebersetzung des ersten Teils von Eu I er' s ", lntt-oductio in Analysin infinitoJ-um" dienen. Diese: durch den Reichtum seine: Inhalts, durch die Feinheit der Methoden und durch die ausserordentliche Klarheit und Pracision der Darstellung ausgezeichnete, in arithmetischer Weise aufgebaute -werk, welches weite Perspectiven eroeffnet, ist h!ltlt- zutage, trotzdem oder vielleicht gerade weil fast alle neueren Lehr- biicher aus ihm als aus einer nie versiegenden Quelle schoepfen, schon halb in Vergcst;enheit geraten, und dies ist um so mehr zu bedauern, als sich dem Anscheine nach die Erkenntnis geltend macht, dass eine scharfere Bestimmung der Begriffe auch eine weitere Entwicklung der Analysi: mit E uler' sehen Reminiscenzen auf rein arithmetischer Grundlage ermoeglichen durfte.
