Pythagoras

Mathematician. Philosopher. World traveler. Pythagoras was an intelligent and curious scholar and teacher. While he's best known for the Pythagorean theorem, he shared ideas about numbers, animals and many other areas of knowledge with his students. Since none of his writings were left behind, it's not always easy for historians to know what's true about Pythagoras and what may be legendary. What does seem apparent is that he was a vegetarian but not a trendy dresser. Some people saw him as godlike. Others felt he made false claims about things. No matter what, Pythagoras's curiosity and willingness to grapple with complex issues have helped further the knowledge of mathematics and philosophy for thousands of years.
