The story
- French · calque oftour d'ivoire
- English todayivory tower
Calque of French tour d'ivoire, based on a biblical phrase, coined by Charles Augustin Sainte-Beuve to compare the poet Alfred de Vigny (more isolated) with Victor Hugo (more socially engaged). First attested in English in a translation of Laughter by French philosopher Henri Bergson (1911). The term was popularized in The Ivory Tower (1917) by Henry James, though used in different sense (millionaires, not professors).
