Calque of French tour d'ivoire, based on a biblical phrase,[1] coined by Charles Augustin Sainte-Beuve to compare the poet Alfred de Vigny (more isolated) with Victor Hugo (more socially engaged).[2][3]
First attested in English in a translation of Laughter by French philosopher Henri Bergson (1911).[4][2][5] The term was popularized in The Ivory Tower (1917) by Henry James,[2] though used in different sense (millionaires, not professors).
