Leonhard Euler:
“The Master of All Fields
“Mathematics is the queen of the sciences.”

Life:
Leonhard Euler was born on April 15, 1707, in Basel, Switzerland. He became one of the most prolific mathematicians in history, contributing to nearly every field of mathematics, as well as physics, astronomy, and engineering. Euler studied under Johann Bernoulli at the University of Basel, later working at the St. Petersburg and Berlin Academies of Science. He lost his sight later in life but continued producing groundbreaking work through dictation. He died on September 18, 1783, in St. Petersburg, Russia.
Works:
Leonhard produced influential works that shaped mathematics and science:

Achievements:
Euler introduced much of the modern mathematical notation, including the function notation f(x), the letter e for the base of natural logarithms, and the use of i for the imaginary unit. He made foundational contributions to number theory, graph theory, calculus, mechanics, and fluid dynamics. His productivity and depth influenced mathematics for centuries.
