Pythagorion's most famous son

I suspect we can all guess who Pythagorion's most famous son is, but most of us probably didn't know he was a Samian. I refer of course to the man whose theorem is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

A statue of Pythagoras adorns the modern Pythagorio waterfront. People look at it and photograph it while muttering the famous right-angled triangle rule to themselves, but I wonder how many realise Pythagoras of Samos was as famous in his own day as a philosopher as a mathematician. The irony is that many of the accomplishments credited to Pythagoras may actually have been accomplishments of his colleagues or successors. Also that it was Pythagoras who styled himself as a philosopher. I don't suppose it really matters much since almost every schoolchild the world over knows the name of Pythagoras today, so genius or charlatan his name has stood the test of time.
