Leonhard Euler

Leonhard Euler (15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer. He made important and influential discoveries in many branches of mathematics, such as infinitesimal calculus and graph theory. Euler is credited for introducing the greek letter pi to denominate the Archimedes constant. His collected works fill 92 volumes, more than anyone else in the field.

About Leonhard Euler in brief

Summary Leonhard EulerLeonhard Euler (15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer. He made important and influential discoveries in many branches of mathematics, such as infinitesimal calculus and graph theory. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. Euler is credited for introducing the greek letter pi to denominate the Archimedes constant. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis. He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia. He was one of the most eminent mathematicians of the 18th century and is held to be the greatest in history. His collected works fill 92 volumes, more than anyone else in the field. He died in Paris in 1783 and is buried in the Père-Lachaise Cemetery in Paris, with his wife, Countess Euler, and their three children. His works are published by the University of Basel in Switzerland and by the Breslau University in Germany in Germany and Austria in the United States in the same order as they were published in 1720 and 1730. He had a son, Johann Heinrich, and a daughter, Maria Magdalena, who died in childbirth in 1805. Eulers had three children, Anna Maria and Maria Magalena, and one son, John Heinrich Euler. They lived in Riehen, Switzerland, where he was sent to live with his maternal grandmother.

In 1723, he was receiving Saturday afternoon lessons from Johann Bernoulli, who quickly discovered his new pupil’s incredible talent for mathematics. At that time Euler’s main studies included theology, Greek and Hebrew at his father’s urging to become a pastor. He completed a dissertation on the propagation of sound with the title De Sono in 1726, and later won the Paris Academy Prize Problem competition twelve times. He took up a post at the Imperial Russian Academy of Sciences in St. Petersburg in 1727. The academy was established by Peter the Great to improve education in Russia and to improve the scientific gap with Western Europe. The Academy’s benefactress, Catherine I, who had a few students enrolled in the academy, offered Euler a job to lessen the faculty’s teaching burden. In November 1726 Euler eagerly accepted the offer, but delayed making the trip to Saint Petersburg while he unsuccessfully applied for a physics professorship. He settled into a position in the mathematics department and settled into an additional job as a medic in the Russian Navy. He later became known as the “father of naval architecture” Euler also mastered Russian life in St Petersburg and lived in the city until his death in 1883. His wife, Marguerite née Brucker, was a pastor of the Reformed Church, and was another pastor’s daughter. She was a friend of the Bernouelli family.
