Euclid of Alexandria, was a Greek mathematician, often referred to as the " Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323 - 283 BC). His Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century.

Euclid was a Greek mathematician three centuries before Christ, who taught at the ancient Library of Alexandria and laid out the principles that came to define Euclidean geometry. His masterwork, Stoicheia (Elements), is a 13-volume exploration all corners of mathematics, based on the works of Aristotle, Eudoxus of Cnidus, Plato, Pythagoras, and others who came before him. Little is known about his life, and what little is recounted is often in error, as the name Euclid was fairly common in his time and place.

He is sometimes credited with one original theory, a method of exhaustion through which the area of a circle and volume of a sphere can be calculated, but he left a much greater mark as a teacher. He presented the theorems and problems with great clarity, showed the solutions concisely and logically, and his Elements has remained a standard geometry text for more than two thousand years since his death.
