Euklidas

This name derives from the Ancient Greek “Eukleídēs (Εὐκλείδης),” composed of two elements: “eû ‎(εὖ)” (well) plus “kléos (κλέος)” (rumor, report, good report, fame, glory). In turn, the name means “one who has a good reputation, glorious, renowned, well known.” Euclid, also known as 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. His Elements is one of the most influential works in the history of mathematics, serving as the leading textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th-century.
