14. Euclid

Euclid was born on 300BC. Very little is known about him. "Euclid" is a Greek word meaning "Good Glory". He is also known as "Euclid of Alexanderia".
                  He was a Greeek  Mathematician and often reffered to as "Father of Geometry". He lived in Alexaderia, Egypt. He was active in Hellenistic Alexanderia during the reign of Ptolemy (323-283 BC).
                   His book "Euclid's Elements" is the most infuencial book in the history of Mathematics. His book was the main textbook of Mathematics (especially Geometry) till early 20th century.
                   In it, principles of "Euclidean Geometry" were deduced from a small set of axioms. Euclid also wrote works on prospective, conic sections, spherical geometry, number theory and rigor.
                   It was due to him that "Geometry" became an important branch of Mathematics.
