Euclid of Alexandria

Euclid of Alexandria was a Greek mathematician active around 300 BCE, often called the "Father of Geometry." He is best known for his work "Elements," which systematically organized and presented the principles of geometry and number theory. In this influential text, Euclid introduced definitions, postulates (basic assumptions), and logical proofs that formed the foundation for geometry. His approach shaped mathematical education for centuries, using clear, logical arguments to establish theorems. Euclid’s work laid the groundwork for future mathematics, influencing fields such as algebra and number theory, making him a pivotal figure in the history of mathematics.
