Diogenes of Sinope (412–323 BCE)

Lived in a barrel in the Athens marketplace. Famous for stunts such as carrying an oil lamp in daylight, saying "I'm looking for an honest man". Once, Alexander the Great, the king that had conquered the known world, visited Diogenes and asked if there was anything he could do for him. To which Diogenes replied "For the present, that you stand a little out of my sun".
