# Eurler Leonhard

### (1707-1783)

The greatest mathematician of the eighteen century,**Leonhard Eurler **was born in Basel,Switzerland. There he studied under another giant of mathematics, **Jean Bernoulli** in 1731 Euler became a proffessor of physics and mathematics at St. peteburg Academy of sciences. Eurler was the most prolific mathematician of all time, pubishing over
*800 different books and papers*. His influence was felt in physics and astronomy as well. Euler's work on mathematical analysis,
__Introduction in analysin infinitorium__ (1748) remained a standard text book over a century. For the princess of Anhalt-Dessau he wrote *Lettre à une princesse D'Allemagne*,
giving a clear non-technical ouline of the main physical theorie of the time.
One can hardly write mathematical equations without copying Euler. Notation still in use today such as *e* and
