Early Life and Education

Born on April 15, 1707, in Basel, Switzerland, Leonhard Euler was raised in a devout Protestant family and showed an early aptitude for mathematics. At the age of 13, he enrolled at the University of Basel, where he excelled under the mentorship of renowned mathematician Johann Bernoulli.

First Mathematical Achievements

Euler published his first mathematical paper, “Solutio problematis ad geometriam situs pertinentis” (Solution to a Problem in the Geometry of Position), at just 17 years old, marking the start of his illustrious career.

St. Petersburg Academy and Early Contributions

In 1727, Euler joined the St. Petersburg Academy of Sciences in Russia, where he made significant advancements in mathematics, physics, and astronomy over the course of 25 years.

Groundbreaking Work in Number Theory

Euler’s contributions to number theory were groundbreaking. He introduced the Euler totient function, which remains a fundamental tool in modern number theory and cryptography, and played a pivotal role in exploring properties of prime numbers.

Contributions to Calculus and Mathematical Unification

Euler’s work in the calculus of variations, differential equations, and his famous formula, e^ix = cos(x) + i sin(x), connected key mathematical constants and showcased his remarkable ability to unify different branches of mathematics.

Prolific Writing and Diverse Contributions

Over his career, Euler authored more than 850 research papers, making significant contributions to graph theory, topology, mechanics, and optics, laying the foundation for future discoveries in these fields.

Personal Challenges and Later Years

Despite suffering from deteriorating eyesight, which led to blindness, Euler continued to pursue his passion for mathematics, relying on his memory and assistance from his sons to continue writing papers and lecturing.

Leonhard Euler's Quote's

“All truths are easy to understand once they are discovered; the point is to discover them.”
“Geometry possesses two great treasures: one is the theorem of Pythagoras, and the other is the division of a line into extreme and mean ratio; the first we may compare to a measure of gold, the second we may name a precious jewel.”
“He who understands Archimedes and Apollonius will admire less the achievements of writers on natural philosophy in recent times.”
“The study of mathematics, like the Nile, begins in minuteness but ends in magnificence.”

Legacy and Recognition

Euler’s impact on mathematics and science is immense. His textbooks, such as “Introductio in analysin infinitorum,” are considered seminal works. Euler was appointed to prestigious academic societies and his name is memorialized in mathematical concepts like Euler’s number and Euler’s formula.

Death and Enduring Legacy

Leonhard Euler passed away on September 18, 1783, due to a brain hemorrhage in St. Petersburg. His contributions revolutionized mathematics and his legacy as one of the greatest thinkers in history continues to inspire mathematicians and scientists worldwide.

Leonhard Euler's Interesting Facts

Euler was an incredibly prolific mathematician, producing over 800 books and papers throughout his career. His works spanned various mathematical disciplines and laid the foundations for much of modern mathematic

Euler gradually lost his eyesight in his right eye due to a childhood fever, and in 1771 he became completely blind in both eyes. Despite this setback, he continued to work and produce groundbreaking mathematics.

Euler introduced many symbols and notations that are widely used today. He popularized the use of the Greek letter π for representing the ratio of a circle's circumference to its diameter and the letter e for Euler's number.

Euler is often regarded as the founder of graph theory. In 1736, he solved the famous Seven Bridges of Königsberg problem, proving that it was impossible to find a walk crossing each bridge exactly once in the city of Königsberg.
