About Euclid

Who is it?: Mathematician - Euclidean Geometry, Euclid's Elements and Euclidean Algorithm
Birth Place: Alexandria, Greek
Residence: Alexandria, Hellenistic Egypt
Known for: Euclidean geometry Euclid's Elements Euclidean algorithm
Fields: Mathematics


Euclid was born in Alexandria, Greek, is Mathematician - Euclidean Geometry, Euclid's Elements and Euclidean Algorithm. Euclid was a great Greek mathematician. Although little is known about his early and personal life, he went on to contribute greatly in the field of mathematics and came to known as the ‘Father of Geometry’, Euclid is known to have taught mathematics in Ancient Egypt during the reign of Ptolemy I. He wrote ‘Elements’, the most influential mathematical works of all time, which served as the main textbook for teaching mathematics from its publication until the late 19th or early 20th century. Elements aroused interest of the Western World and mathematicians around the globe for over 2000 years. Euclid used the ‘synthetic approach’ towards producing his theorems, definitions and axioms. Apart from being a tutor at the Alexandria library, Euclid coined and structured the different elements of mathematics, such as Porisms, geometric systems, infinite values, factorizations, and the congruence of shapes that went on to contour Euclidian Geometry. His works were heavily influenced by Pythagoras, Aristotle, Eudoxus, and Thales to name a few.

Famous Quotes:

If a straight line be cut into equal and unequal segments, the rectangle contained by the unequal segments of the whole together with the square on the straight line between the points of section is equal to the square on the half.



The Papyrus Oxyrhynchus 29 (P. Oxy. 29) is a fragment of the second book of the Elements of Euclid, unearthed by Grenfell and Hunt 1897 in Oxyrhynchus. More recent scholarship suggests a date of 75–125 AD.


Very few original references to Euclid survive, so little is known about his life. He was likely born c. 325 BC, although the place and circumstances of both his birth and death are unknown and may only be estimated roughly relative to other people mentioned with him. He is rarely mentioned by name by other Greek mathematicians from Archimedes (c. 287 BC – c. 212 BC) onward, and is usually referred to as "ὁ στοιχειώτης" ("the author of Elements"). The few historical references to Euclid were written centuries after he lived, by Pappus of Alexandria c. 320 AD and Proclus c. 450 AD.


Although best known for its geometric results, the Elements also includes number theory. It considers the connection between perfect numbers and Mersenne primes (known as the Euclid–Euler theorem), the infinitude of prime numbers, Euclid's lemma on factorization (which leads to the fundamental theorem of arithmetic on uniqueness of prime factorizations), and the Euclidean algorithm for finding the greatest Common divisor of two numbers.


The geometrical system described in the Elements was long known simply as geometry, and was considered to be the only geometry possible. Today, however, that system is often referred to as Euclidean geometry to distinguish it from other so-called non-Euclidean geometries that mathematicians discovered in the 19th century.
