Leonhard Euler Biography
Birthday: April 15, 1707 (Aries)
Born In: Basel
Leonhard Euler, the 18th century Swiss mathematician and physicist is considered to be one of the greatest mathematicians of all time for the tremendous contributions he made to the field of pure mathematics. Many concepts of modern mathematics originated from the works of this eminent mathematician whose works also spanned the fields of mechanics, fluid dynamics, optics and astronomy. Euler’s interest in mathematics stemmed from his childhood when his father would teach him the subject. As luck would have it, Johann Bernoulli, Europe’s foremost mathematician of his time, was a friend of Leonhard’s father and the influence of this great mathematician on the young Leonhard was immense. Euler’s father wanted to prepare him for a career in theology and it was Bernoulli who persuaded his friend to let the boy study mathematics. Throughout his working career Euler authored several textbooks and memoirs in which he introduced many concepts, especially in the area of mathematical analysis. A prolific mathematician, his works cover several areas of the subject such as algebra, geometry, calculus, trigonometry and number theory. Two numbers are named after him: Euler's Number in calculus, e, and Euler-Mascheroni Constant, γ, also called “Euler’s constant”. He was plagued by deteriorating eyesight which rendered him almost blind, yet his productivity never suffered.
