Scholarch

A scholarch (Ancient Greek: σχολάρχης, scholarchēs) was the head of a school in ancient Greece. The term is especially remembered for its use to mean the heads of schools of philosophy, such as the Platonic Academy in ancient Athens. Its first scholarch was Plato himself, the founder and proprietor. He held the position for forty years, appointing his nephew Speusippus as his successor. The members of the Academy elected later scholarchs.
