On the subject of death, Euler was resigned, offering a typical Calvinist view. He remarried Katherina’s half-sister in 1776. They had 13 children, but only five survived childhood. In 1734, whilst living in Russia, he married Katharina Gsell. However, after the death of Peter and Catherine I, fewer funds were available. The Academy of Sciences had been founded by Peter the Great to improve education in Russia. While in Russia, Euler soon picked up the Russian language and also worked as a medic for the Russian Navy. In 1726, Euler was invited to St Petersburg to work at the Imperial Russian Academy of Sciences, with Daniel Bernoulli. Euler was keen to pursue mathematics, though he never lost his interest in theology and philosophy. Bernoulli was soon aware of the child’s prodigious mathematical talent and Bernoulli successfully encouraged Euler’s father to allow his son to pursue mathematics rather than a career in the church. At the age of just 13, he enrolled at the University of Basel, gaining a degree in Philosophy, but he also studied mathematics at the weekend under the guidance of Johann Bernoulli. His father was a pastor in the Protestant Reformed Church and also a friend of Johann Bernoulli, the greatest mathematician of the age.

Born in Switzerland he spent considerable time in Russia and Prussia.Įuler was born 15 April 1707 in Basel, Switzerland.

His work served as a basis for many other mathematicians and he is widely regarded as the greatest mathematician of all time. Euler also introduced many modern mathematical notations such as π. It is estimated Euler wrote a third of all the mathematic works of the 18th Century. His work was remarkably prolific – running to 70-80 volumes on maths, physics, astronomy and logic. Amongst his many contributions, Euler made discoveries in infinitesimal calculus, graph theory and contributed to topology and analytic number theory. Leonhard Euler (1707 – 1783) was a Swiss mathematician and scientist who made a prolific number of discoveries in mathematics.
