(Breslau, 1741–1800, Vienna), originally Stephan, usually known as Stephanie der Jüngere, was educated at a Gymnasium, served in a Prussian hussar regiment and was taken prisoner in 1760 by the Austrians. He transferred to the Austrian army, but in 1769 became, like his elder brother C. G. Stephanie, an actor in Vienna. He wrote numerous comedies, in which his practical experience of the stage is exploited, and made something of a speciality of plays about military life (see Soldatenstücke), including Die abgedankten Offiziers (1770), Die Kriegsgefangenen (1771), and Der Deserteur aus Kindesliebe (1773). He wrote the libretto for Mozart's Die Entführung aus dem Serail (1782, see Singspiel).
