Euler, Leonhard

Leonhard died in St. Petersburg, Russia while discussing, over lunch, the newly discovered planet Uranus and its orbit with his family and a fellow academician Anders Johan Lexell.
Swiss cartographer/astronomer/physicist, and one of the greatest mathematicians ever, Euler spent
most of his professional life in St. Petersburg (1727–1741), in Berlin until 1766, after which he went
back to Russia. Among the atlases whose preparation he supervised, was the school atlas “Atlas
geographicus omnes orbis terrarum regiones in XLI tabulis… / Atlas géographique représentant en
XLI cartes toutes les regions de la terre…” created under the auspices of the Royal Prussian
Academy of Sciences in Berlin, published in 1753 with 41 maps. This edition includes a title page, a
10-page preface by Leonhard Euler in Latin and French, 41 double-page engraved maps as
mentioned in the title and preface, plus 4 additional maps. The second edition was published in 1760
with 44 maps, followed by the third unaltered edition in 1777, which was printed until 1784. The
maps, mostly based on works of Johann Christoph Rhode, were mostly engraved by Nicolaus
Friedrich Sauerbrey.
