Mirepoix (cuisine)
Similar flavour bases include the Italian "soffritto", the Spanish "sofrito", "refogado/sufrito" (braised onions, garlic and tomato) from Portuguese-speaking nations, the German "suppengrün" (leeks, carrots and celeriac), the Polish "włoszczyzna" (leeks, carrots, celery root and parsley root), the US Cajun / Creole holy trinity (onions, celery and bell peppers), and possibly the French "duxelles" (mushrooms and often onion or shallot and herbs, reduced to a paste).
Nouvelle cuisine
The modern usage is variously attributed to authors Henri Gault, Christian Millau, and André Gayot, who used "nouvelle cuisine" to describe the cooking of Paul Bocuse, Alain Chapel, Jean and Pierre Troisgros, Michel Guérard, Roger Vergé, and Raymond Oliver, many of whom were once students of Fernand Point. Paul Bocuse claimed that Gault first used the term to describe food prepared by Bocuse and other top chefs for the maiden flight of the Concorde airliner in 1969.
