Pythagoras

Pythagoras was born on the Greek island of Samos. Little is known for certain about him, because he wrote nothing and his followers credited many later ideas to him. Ancient writers say he traveled, perhaps to Egypt, and around 530 BC settled in Croton, a Greek city in southern Italy. There he founded a community of followers, men and women, who lived by strict rules: they shared property, kept silence while learning, avoided eating beans, and believed the soul was reborn in new bodies after death. The Pythagoreans taught that number is the key to understanding the world. They discovered that musical harmonies correspond to simple ratios of string lengths, such as two to one for an octave, and they studied odd and even numbers and geometric shapes. The famous theorem about right triangles bears his name, though it was known earlier in Babylon, and it is unclear whether he proved it. The community also became involved in politics, and an uprising eventually drove the Pythagoreans out of Croton. He died around 495 BC.
