Ptolomy I, King of Egypt:

Ptolomy, boyhood friend of Alexander the Great, whom he later served as such a devoted bodyguard that he even kidnapped Alexander's body en route to Macedonia. He diverted it to Alexandria, the first of Alexander's many eponymous city foundations, to make the tomb become the focus of the Ptolemaic ruler cult he established in Egypt. He wrote the first history of Alexander's life and made Alexandria a great center of learning throughout the Hellenistic age housing the world's biggest library with 500.000 volumes and a research Museum which attracted the leading scholars in the world.
