Pythagoras of Samos

c. 570 – c. 495 BC · Mathematics, philosophy

Pythagoras of Samos was a Greek philosopher and mathematician, often described as the first pure mathematician and the founder of the Pythagorean school. The theorem that bears his name — that the square on the hypotenuse of a right triangle equals the sum of the squares on the other two sides — was known to the Babylonians a thousand years earlier, but he or his followers may have been the first to prove it. Historians note the theorem and its proof were most likely the work of his followers rather than Pythagoras himself. The relation is a cornerstone of geometry and the basis of the Pythagorean trigonometric identity.
