   Leonhard Euler. Born 15 April 1707 in Basel, Switzerland Died 18 Sept 1783 in St Petersburg, Russia. Leonhard Euler s father was Paul Euler.  
   http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Euler.html
   
   Extractions: Leonhard Euler 's father was Paul Euler. Paul Euler had studied theology at the University of Basel and had attended Jacob Bernoulli 's lectures there. In fact Paul Euler and Johann Bernoulli had both lived in Jacob Bernoulli 's house while undergraduates at Basel. Paul Euler became a Protestant minister and married Margaret Brucker, the daughter of another Protestant minister. Their son Leonhard Euler was born in Basel, but the family moved to Riehen when he was one year old and it was in Riehen, not far from Basel, that Leonard was brought up. Paul Euler had, as we have mentioned, some mathematical training and he was able to teach his son elementary mathematics along with other subjects. Leonhard was sent to school in Basel and during this time he lived with his grandmother on his mother's side. This school was a rather poor one, by all accounts, and Euler learnt no mathematics at all from the school. However his interest in mathematics had certainly been sparked by his father's teaching, and he read mathematics texts on his own and took some private lessons. Euler's father wanted his son to follow him into the church and sent him to the University of Basel to prepare for the ministry. He entered the University in 1720, at the age of 14, first to obtain a general education before going on to more advanced studies.

   Extractions: Det fortelles at to av Leonhard Eulers elever bad den helt blinde matematikeren om hjelp. De hadde hver for seg lagt sammen sytten ledd, og når de var ferdige skilte resultatene deres seg fra hverandre med ett siffer i den femte desimalen. Euler regnet da ut det hele i hodet - og hans summering var korrekt. Han hadde en enestående hukommelse for siffer og kunne altså dessuten utføre kompliserte regneoperasjoner i hodet. Han var som Isaac Newton og mange andre av den tidens vitenskapsmenn, en flersidig forsker. Forutenom matematikk og fysikk hadde han studert anatomi, kjemi og botanikk. Tidlig mistet han synet på det ene øyet, og de siste fjorten årene var han helt blind. Tross dette omtales han som en glad og livlig person. Leonhard Euler ble født i 1707. Han var sønn til Paul og Marguerite Euler, og familien bodde i nærheten av Basel i Sveits. Faren, som var prest, ville at sønnen skulle studere teologi, men ga slipp på tanken når han la merke til sønnens store interesse for matematikk. Leonhard begynte å studere tidlig. Når han var 17 år forsvarte han en avhandling ved universitetet i Basel og to år senere leverte han to avhandlinger til vitenskapsakademiet i Paris. Den ene bahandlet et problem med fartøy med master (og det av en mann som i sitt hjemland aldri skulle se et skip!), og den andre handlet om lydens filosofi. Dette ble opptakten til en lysende karriere. I 1727 ble han ansatt som forsker i matematikk ved vitenskapsakademiet i St. Petersburg. Seks år senere ble han utnevnt til professor ved akademiet, og samtidig giftet han seg med Catharina Gsell som var datteren til en sveitsisk kunstner. De fikk med tiden tretten barn. I begynnelsen av 1740-tallet ble Euler invitert av kongen av Preussen, Fredrik den store, til Berlin. I 1766 vendte han tilbake til Petersburg for å tilbringe resten av sitt liv der. Når han var 69 år døde hans hustru, men han giftet seg året etter med en halvsøster av Catharina Gsell.

   Extractions: suisse, 1707-1783 Elève de Jean Bernoulli. Sans doute un des plus grands mathématiciens de tous les temps. Il s'installa à Saint Petersbourg auprès de Pierre Ier le Grand (en remplacement de Daniel Bernoulli) puis à Berlin (1741) sous le règne de Frédéric II. Vers la fin de sa vie, alors aveugle, il revint à Saint-Petersbourg invité par Catherine II. Son oeuvre est considérable. Euler intervint dans les trois domaines fondamentaux de la science de son époque : l'astronomie (orbites planétaires, trajectoires des comètes), les sciences physiques (champs magnétiques, hydrodynamique, optique, nature ondulatoire de la lumière,...), et les mathématiques, dans toutes ses branches, de l'arithmétique à la géométrie différentielle en passant par l'analyse numérique et fonctionnelle, le calcul des variations, les courbes et les surfaces algébriques, le calcul des probabilités et les premiers aspects de la théorie des graphes et de la topologie.

   Extractions: By Katerina Kechris Euler was one the leading mathematicians of the 18th century. Although the majority of his work was in pure mathematics, he contributed to other disciplines, such as astronomy and physics, as well. In his lifetime he published more than 500 books and papers, and another 400 were published posthumously. Euler's contributions to mathematics cover a wide range, including analysis and the theory of numbers. He also investigated many topics in geometry. For example, he worked on the mathematics behind the Greek concept of 'Perfect Bodies'. The Greeks defined the perfect body as the form built from identical regular polyhedra. There are only five such polyhedra, the tetrahedron, cube, octahedron, dodecahedron and icosahedron. These concepts were forgotten until the Renaissance, when Pacioli and Leonardo da Vinci studied them. Kepler even tried to relate the perfect bodies to the orbits of the planets. Euler was able to relate the number of faces (F), vertices (V) and edges (E) of a polyhedron by the following equation, F + V = E + 2 from which one can derive that there are only five regular polyhdera.

    Extractions: Leonhard Euler (1707-1783) was arguably the greatest mathematician of the eighteenth century (His closest competitor for that title is Lagrange) and one of the most prolific of all time; his publication list of 886 papers and books may be exceeded only by . Euler's complete works fill about 90 volumes. Remarkably, much of this output dates from the the last two decades of his life, when he was totally blind. Though born and educated in Basel, Switzerland, Euler spent most of his career in St. Petersburg and Berlin. He joined the St. Petersburg Academy of Sciences in 1727. In 1741 he went to Berlin at the invitation of Frederick the Great, but he and Frederick never got on well and in 1766 he returned to St. Petersburg, where he remained until his death. Euler's prolific output caused a tremendous problem of backlog: the St. Petersburg Academy continued publishing his work posthumously for more than 30 years. Euler married twice and had 13 children, though all but five of them died young. Euler's powers of memory and concentration were legendary. He could recite the entire

    Extractions: While Newton (arguably) founded the subject, Euler (pronounced 'oiler') developed all the methods used today in Differential Calculus. Not only was Leonhard Euler the greatest Mathematician of his day (he actually wrote over a quarter of the tracts from the 18th century!), but he wrote in a humbling and readable manner such that anyone with a foundation may approach his proofs. And this text is no different; simply a book any mathematician should own. Truly one of the milestones of Calculus. John D. Blanton did a good job in translating Euler's work on analysis of the infinite. Although I did not read the original copy the book, I could still receive the charm of Euler from the translation. Euler wrote this book because he realized that many mathematics students were lacking of the knowledge of analysis of the infinite. He, as a great master of mathematics and educator and with all his passion, presented this timeless masterpiece to all of us. I recommend this book to every stude...

    Extractions: From `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball. Leonhard Euler I think we may sum up Euler's work by saying that he created a good deal of analysis, and revised almost all the branches of pure mathematics which were then known, filling up the details, adding proofs, and arranging the whole in a consistent form. Such work is very important, and it is fortunate for science when it fall into hands as competent as those of Euler. Euler wrote an immense number of memoirs on all kinds of mathematical subjects. His chief works, in which many of the results of earlier memoirs are embodied, are as follows. In the first place, he wrote in 1748 his Introductio in Analysin Infinitorum , which was intended to serve as an introduction to pure analytical mathematics. This is divided into two parts. The first part of the Analysis Infinitorum contains the bulk of the matter which is to be found in modern text-books on algebra, theory of equations, and trigonometry. In the algebra he paid particular attention to the expansion of various functions in series, and to the summation of given series; and pointed out explicitly that an infinite series cannot be safely employed unless it is convergent. In the trigonometry, much of which is founded on F. C. Mayer's Arithmetic of Sines , which had been published in 1727, Euler developed the idea of John Bernoulli, that the subject was a branch of analysis and not a mere appendage of astronomy or geometry. he also introduced the trigonometrical functions, and shewed that the trigonometrical and exponential functions were connected by the relation
