Biography:

Leonhard Euler was born on April 15, 1707, in Basel, Switzerland. He attended the University of Basel and earned his master's during his teens. He is moving to Russia in 1727 and join the St. Petersburg Academy as a professor of physics.

In 1727, he was recognized as a genus whereas he had 20 years old.

He wed Katharina Gsell in early 1734, with the couple going on to have many children, though only five lived past their father. The couple were married for 39 years until Katharina's death, and Euler remarried in his later years to her half-sister.

In 1735, he had an overexertion due to cartography work and was severely hampered in the ability to see from his right eye. In 1736, he published his first book.

In 1740, Euler was appointed the mathematics director of the newly created Berlin Academy of Science and Beaux Arts. In 1766, he returned to Russia to head the St. Petersburg Academy.

In 1770, Euler had lost his sight completely but he was able to continue his scientific work with assistance that published scores of articles.

Euler had a health a little bite delicate. He had lost his left eye in 1771 as a result of a cataract. He was blind during 12 years.

Euler, working on the day of his passing, suffered from a brain haemorrhage and died during the night of September 18, 1783, in St. Petersburg.

There is one opera with the thema of Leonhard Euler: Leonhardi Euleri Opera Omnia in 2014.

Leonhard Euler had work about geometry, trigonometry, calculus, differential equations, number theory and notational systems and use π and f(x). Euler's Identity theorem is often cited as the most delightful of equations and his work also focused on the fields of astronomy/lunar motion, acoustics, mechanics and music.

Euler worked about all scientifically questions of his time. He have many formulas with his name. He is the scientist the most fruitful of his time.
