What is "dorvigny"

Louis-François Archambault (30 March 1742, Paris - 5 January 1812, Paris), stage name Dorvigny, was a French novelist, actor and playwright, and the inventor of "janotism" (gross errors of language for comic effect).

Said to be an illegitimate son of Louis XV of France, he began his acting career under Nicolet and put on plays at the Théâtre des Variétés-Amusantes, the Théâtre de l'Ambigu-Comique, the Grands-Danseurs du Roi, the Théâtre des Délassements-Comiques and the Théâtre des Associés.
