Pythogoras of Samos
The discoverer of the Pythagorean theorem was born less than two kilometers off the west coast of Turkey, on the Greek island of Samos.
He left no writings, but established a school to teach mysticism as well as mathematics. The idea that "all is number" was dominant. Odds were female, evens male and each number had meaning, eg. three: harmony.
Under his tutelage, students were vegetarians, following secret rites and bizarre prohibitions. He also extended and developed Pythagorean mathematical and scientific ideas.
