Here maybe---but probably not---Christopher Columbus (1451--1506) met the professors to debate his proposed voyage (see Wikipedia: University of Salamanca: History).
He didn't have to convince them that the Earth was round: they already knew that---it had been established theory in western Eurasia (among the intellectual elite at least) since Greco-Roman antiquity (see Wikipedia: Spherical Earth theory).
And Columbus never did get to China or India.
It just goes to show you should always listen to your professors, right?
