Historical and Biographical Resources
Euler Opera Omnia
Published by Birkhäuser and the Euler Commission of Switzerland, the Opera Omnia is the definitive print source for Euler's works. Publication began in 1911, growing to scores of volumes comprising nearly all of Euler's works.
Put simply, the Opera Omnia is the authoritative source of Euler's works. Not only do his writings appear in neatly typeset, edited form, but each volume also includes commentaries—some of them very lengthy and very scholarly—on those works. The Opera Omnia can be found in many large research libraries, and is well worth the time spent with it.
Most recently, Springer has been publishing volumes of Euler's correspondence, and has several more volumes in preparation.

 Bradley, Robert, and Sandifer, Edward. (Editors.) Leonhard Euler: Life, Work and Legacy.
(Studies in the History and Philosophy of Mathematics, Volume 5) Elsevier Science, 2007.

Description from Amazon.com:
The year 2007 marks the 300th anniversary of the birth of one of the Enlightenment's most important mathematicians and scientists, Leonhard Euler. This volume is a collection of 24 essays by some of the world's best Eulerian scholars from seven different countries about Euler, his life and his work.
Some of the essays are historical, including much previously unknown information about Euler's life, his activities in the St. Petersburg Academy, the influence of the Russian Princess Dashkova, and Euler's philosophy. Others describe his influence on the subsequent growth of European mathematics and physics in the 19th century. Still others give technical details of Eulers innovations in probability, number theory, geometry, analysis, astronomy, mechanics and other fields of mathematics and science.

 Sandifer, C. Edward. The Early Math of Leonhard Euler.
(Volume 1: The MAA Tercentary Euler Celebration.) Mathematical Association of America, 2007.

Description from MAA Online:
The Early Mathematics of Leonhard Euler describes Euler's early mathematical works: the 50 mathematical articles he wrote before he left St. Petersburg in 1741 to join the Academy of Frederick the Great in Berlin. These works contain some of Euler's greatest mathematics: the Konigsburg bridge problem, his solution to the Basel problem, his first proof of the EulerFermat theorem. It also presents important results that we seldom realize are due to Euler: that mixed partial derivatives are equal, our f(x) notation, and the integrating factor in differential equations. The book provides some of the way mathematics is actually done. For example, Euler found partial results towards the EulerFermat theorem well before he discovered a proof of the Fermat theorem itself, and the EulerFermat version came 30 years later, beyond the scope of this book.
The book shows how results in diverse fields are related, how number theory relates to series, which, in turn relate to elliptic integrals and then to differential equations, There are dozens of such strands in this beautiful web of mathematics. At the same time, we see Euler grow in power and sophistication, from his first work on differential equations as an 18year old student, a paper with a serious flaw in it, to the most celebrated mathematician and scientist of his times, when, at the age of 34, he was lured away like a superstar athlete might be traded today. The book is a portrait of the world's most exciting mathematics between 1725 and 1741, rich in technical detail. Woven with connections within Euler's work and with the work of other mathematicians in other times and places, laced with historical context.

 Dunham, William. (Editor.) The Genius of Euler: Reflections on his Life and work.
(Volume 2: The MAA Tercentary Euler Celebration.) Mathematical Association of America, 2007.

Description from MAA Online:
This book celebrates the 300th birthday of Leonhard Euler (17071783), one of the brightest stars in the mathematical firmament. The book stands as a testimonial to a mathematician of unsurpassed insight, industry, and ingenuity—one who has been rightly called "the master of us all." The collected articles, aimed at a mathematically literate audience, address aspects of Euler's life and work, from the biographical to the historical to the mathematical. The oldest of these was written in 1872, and the most recent dates to 2006.
Some of the papers focus on Euler and his world, others describe a specific Eulerian achievement, and still others survey a branch of mathematics to which Euler contributed significantly. Along the way, the reader will encounter the Königsberg bridges, the 36officers, Euler's constant, and the zeta function. There are papers on Euler's number theory, his calculus of variations, and his polyhedral formula. Of special note are the number and quality of authors represented here. Among the 34 contributors are some of the most illustrious mathematicians and mathematics historians of the past century, e.g., Florian Cajori, Carl Boyer, George Pólya, Andre Weil, and Paul Erdös. And there are a few poems and a mnemonic just for fun.

 Dunham, William. Euler: The Master of Us All. Mathematical Association of America, 1999.

Reknowned mathematics author William Dunham's book is the most complete examination in English of Euler's
mathematical work. Written for the mathematically literate (The reader should be familiar with calculus),
Dunham examines selected mathematics of Euler, and places his work in a historical context. Over eight
chapters, Dunham looks separately at some of Euler's contributions to Number Theory, Logarithms, Infinite
Series, Analytic Number Theory, Complex Variables, Algebra, Geometry, and Combinatorics. Dunham's book
also contains a brief biography of Euler.

 Truesdell, Clifford. An Idiot's Fugitive Essays on Science Methods – Methods, Criticism, Training, Circumstances. New York: SpringerVerlag, 1984.

Description from a review by Ed Sandifer:
In an era when most Euler scholarship was done in the Soviet Union and in the DDR, Truesdell kept
the candle lit in the West, though his work and his personality were both controversial... This volume
contains 42 "Fugitive essays", about a third of which directly concern Euler, and more than half of
the rest involving Euler indirectly.... the Fugitive Essays ought to be required reading for anyone
trying to understand Euler. They are entertaining, opinionated, well informed and at times controversial.

of Euler's death. Rudio was a founding member of the editorial committee of the Opera Omnia and edited
several of the early volumes, including some on number theory.

18th Century Science
The Eighteenth Century is the height of the Enlightenment, and is an important and fascinating period
of time in the History of Science. It's a slightly confusing time, however, with academies,
societies, and monarchs controlling almost all science and scientists of the day. If you're looking for
a good starting place to learn more about this time, and to put Euler's work in a good historical context,
The Euler Archive suggests the following books:
 Bertrand, Joseph. L'Académie des Sciences et les Académiciens de 1666
à 1793. (French) Amsterdam: B. M. Israël, 1969.
 Boss, Valentin. Newton & Russia: The Early Influence, 16981796.
