Leonhard Euler


Leonhard Euler was a famous Swiss mathematician, physicist, geographer, & astronomer. He is also the founder of graph theory and topology. He was born on 15 April 1707 in Basel, Swiss Confederacy. Leonhard died on 18 September 1783 at the age of 76 years in Saint Petersburg, Russian Empire after lunch with his family. He is best known for his work in fluid dynamics, mechanics, astronomy, optics, and music theory. His father was Paul III Euler and his mother was Marguerite. He has two sisters (Anna Maria and Maria Magdalena) and a younger brother (Johann Heinrich).

He started his early education at a very young age in mathematics. Then he goes to Latin School in Basel at the age of 8 and to the University of Basel at the age of 13 (1720).

Leonhard married to Katharina Gsell (1707–1773) on January 7, 1734. He is the father of 13 children, but unfortunately, only 5 survived, 2 daughters and 3 sons. After the death of his first wife, Leonhard married her half-sister Salome Abigail Gsell (1723–1794).
