Private lessons, however, he refused because of his busy schedule. Here's how Euler puts it in his autobiography: "the famous professor Johann Bernoulli made it a special pleasure for himself to help me along in the mathematical sciences. Johann Bernoulli and Euler soon got to know each other better. The course on elementary mathematics was given by Johann Bernoulli, the younger brother of the deceased Jacob Bernoulli. Attending university at such a young age was not unusual at the time. In 1720, at thirteen years of age, Euler enrolled at the University of Basel. In addition, he received private tutoring from Johannes Burckhardt, a young theologian with a keen interest in mathematics. Around the age of eight, Euler was sent to live at his maternal grandmother's house and enrolled in the Latin school in Basel. įrom a young age, Euler received schooling in mathematics from his father, who had taken courses from Jacob Bernoulli some years earlier at the University of Basel. Soon after the birth of Leonhard, the Euler family moved from Basel to the town of Riehen, Switzerland, where his father became pastor in the local church and Leonhard spent most of his childhood. He was the oldest of four children, having two younger sisters, Anna Maria and Maria Magdalena, and a younger brother, Johann Heinrich.
Leonhard Euler was born on 15 April 1707, in Basel, Switzerland, to Paul III Euler, a pastor of the Reformed Church, and Marguerite ( née Brucker), whose ancestors include a number of well-known scholars in the classics.

He became famous, among others, for solving the Basel problem, after proving that the sum of the infinite series of squared integer reciprocals equaled exactly π 2/6, and for discovering that the sum of the numbers of vertices and faces minus edges of a polyhedron equals 2, a number now commonly known as the Euler characteristic. Įuler was also the first practitioner of graph theory (partly as a solution for the problem of the Seven Bridges of Königsberg). He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia.Įuler is credited for popularizing the Greek letter π, the base of the natural logarithm, now known as Euler's number. A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss remarked: "The study of Euler's works will remain the best school for the different fields of mathematics, and nothing else can replace it." Euler is also widely considered to be the most prolific his more than 850 publications are collected in 92 quarto volumes, (including his Opera Omnia) more than anyone else in the field. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory.Įuler is held to be one of the greatest mathematicians in history and the greatest of the 18th century.
He introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. Leonhard Euler ( / ˈ ɔɪ l ər/ OY-lər, German: ( listen) 15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He is listed by an academic genealogy as the equivalent to the doctoral advisor of Joseph Louis Lagrange.He is the father of the mathematician Johann Euler.
