Euclid, fl. 300 BCE, also known as Euclid of Alexandria, is popularly known as the "Father of Geometry." He is believed to have been active in Alexandria during the reign of Ptolemy I (323 BCE–283 BCE). His Elements is the most successful textbook in the history of mathematics. In it, the principles of what is now called Euclidean geometry are deduced from a small set of axioms.

Although many of the results in Elements originated with earlier mathematicians, one of Euclid's accomplishments was to present them in a single, logically coherent framework, which is easy to use and easy to reference. His system of rigorous mathematical proofs remains even now, twenty-three centuries later, the basis of mathematics.
