" The professors all came from France. Scholastics, students of theology, came in their twenties to teach the grammar classes for 2 or 3 years before returning to France. The priests came in their thirties and spent at least a quarter century in New France, alternating between their roles as professor and missionary to the natives. Some devoted themselves entirely to education. The college had among its professors Father Pierre-François-Xavier de CHARLEVOIX, once Voltaire's master, whose Histoire et description générale de la Nouvelle France was published in Paris in 1744."
