Leonhard Euler History Timeline and Biographies

1707

Birth of Leonhard Euler

Leonhard Euler was born on April 15, 1707, in Basel, Switzerland. He was the son of a pastor and was introduced to mathematics at an early age. His early education laid the foundation for his future contributions to mathematics and physics.

1727

Enrollment at the University of Basel

At the age of 20, Leonhard Euler enrolled at the University of Basel, where he studied mathematics under the guidance of Johann Bernoulli. Euler's time at the university significantly shaped his mathematical career and interests.

1733

First Publication: "Mechanica"

Leonhard Euler published his first major work, "Mechanica," in 1733, which dealt with the principles of mechanics and laid the foundations for his future studies in physics and engineering.

1741

Introduction of Function Notation

Euler introduced the modern concept of a function in his work "Introductio in analysin infinitorum," where he used the notation \( f(x) \) to describe functions, revolutionizing mathematical analysis.

1748

Publication of "Institutiones Calculi Differentialis"

In 1748, Leonhard Euler published "Institutiones Calculi Differentialis," which formalized the principles of differential calculus and contributed to the development of mathematical notation.

1750

Euler's Work on Graph Theory

Euler made significant contributions to graph theory with his solution to the Seven Bridges of Königsberg problem in 1750, which laid the groundwork for topology and combinatorics.

1755

Publication of "Elementa Matheseos"

Leonhard Euler published "Elementa Matheseos," a comprehensive introduction to mathematics which included topics in algebra, geometry, and calculus, further establishing his reputation as a leading mathematician.

1760

Euler's Contributions to Number Theory

Euler published several important papers on number theory, including his work on prime numbers and the introduction of the Euler's totient function, which is crucial in number theory today.

1770

Euler's Work in Astronomy

Euler contributed to astronomy by developing methods for calculating the orbits of celestial bodies. He published works that advanced the understanding of planetary motion.

1775

Establishment of Euler's Formula for Complex Analysis

In 1775, Leonhard Euler formulated his famous formula \( e^{ix} = \cos(x) + i\sin(x) \), which connects complex analysis and trigonometry, and is considered one of the most beautiful equations in mathematics.

1783

Publication of "Theoria Motus Corporum Coelestium"

Euler published "Theoria Motus Corporum Coelestium," which detailed the motion of celestial bodies and solidified his contributions to celestial mechanics.

1787

Euler's Work on Elasticity

In 1787, Euler published significant works on the theory of elasticity, which laid the groundwork for modern engineering and material science.

1790

Death of Leonhard Euler

Leonhard Euler passed away on September 18, 1783, in St. Petersburg, Russia. His extensive body of work and contributions to mathematics continue to influence the field and inspire future generations of mathematicians and scientists.
