Junia, a Greek woman. She is often excluded from history because Greeks/Roman didn't want to acknowledge a woman knew anything more than males.

Socrates says that he had 3 teachers. Diotima of Mantinea (reference in the Symposium), Asphasia of Miletus who he said taught him rhetoric and the Pythian Oracle at Delphi who set him on his philosophical quest.

There is an article about these women at women-philosophers.com
