"An academy is an institution of secondary education or higher learning, research, or honorary membership. The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia (...) north of Athens, Greece".
This has been the early prototype for later roman, middle-ages, renaissance and finally modern colleges.
It wasn't the first teacher or even school were children were taught, but it was the first higher learning institution, with organized courses and mostly modern form.

Comparing it to the "guy who invented language"? As if it's something communally developed, whose origins are lost in prehistoric times? Really?
