The Euler Lecture (Euler-Vorlesung in Sanssouci) is a mathematics lecture given at an annual event at the University of Potsdam (Universität Potsdam). The event, initiated in 1993,^[1] is organized by the Universität Potsdam, Institut for Mathematik, the Humboldt-Universität zu Berlin, Institut für Mathematik, and the Berliner Mathematische Gesellschaft [de] with the assistance of several other organizations, including the Freie Universität Berlin, Fachbereich Mathematik und Informatik, the Technische Universität Berlin, Institut für Mathematic, the Zuse-Institut Berlin (ZIB), and the Deutsche Mathematiker-Vereinigung (DMV).^[2] The mathematical lecturer is selected by a distinguished jury. The event also contains a historical lecture (Vortrag) and a musical program supporting the event.^[1]

The Euler Lecture is named in honor of Leonhard Euler, who spent the years from 1741 to 1766 in Berlin and during that time wrote approximately 380 works.^[3] Among other things, Euler worked for many years as director of the mathematics section at the Prussian Academy of Sciences and as a consultant at the court of Frederick the Great in Potsdam.^[1][3]

The Euler Lecture should not be confused with the Ulf von Euler Lecture, an annual lecture sponsored by the Karolinska Institute and named in honor of the Swedish physiologist Ulf von Euler (1905–1983).^[4]

The organizers of the Euler Lecture maintain an archive of lectures starting in 1993.^[5]
