Leonhard Euler was a Swiss mathematician and physicist who made many pioneering contributions to mathematics and physics in the 18th century. He showed early talent in mathematics and was tutored by one of Switzerland's leading minds. Euler accepted positions at academies in St. Petersburg and later Berlin where he developed formulas still used today, such as using Pi to represent the ratio of a circle's circumference to its diameter. Late in life, Euler suffered a brain hemorrhage and died after listening to a fellow scientist discuss the mathematical formula for determining Uranus' orbit.

2. Early LifeEuler was born in Switzerland and from an early age showed great potential as a physicist His farther happened to be friends with one of Switzerland's smartest minds and he agreed to tutor young Euler.He was later offered a professorship at an academy at ST. Petersburg, he gladly accepted.

3. Contributions' to mathEuler was having trouble in Russia and so when he was offered a job for the Prussians in Berlin he quickly moved and continued his research.There, he pioneered formulas amongst other things that are still in use today. Like his idea to use Pi to denote the ration of a circle’s circumference to its diameter.

4. Other contributions and deathOne other formula he is famous for is known as Euler’s identity show here:Euler’s death is one person’s opinion ironic. Late in his life Euler is listening to one of his fellow scientists discuss the mathematic formula to find the orbit of the planet Uranus which was newly discovered, upon hearing this he suffered a brain hemorrhage and later died.
