Jung-Stilling (Johann Heinrich Jung), a German mystic, born at Im-Grund, Nassau, Sept. 12,1740, died in Carlsruhe, April 2, 1817. After being successively a charcoal burner, tailor, and teacher, he began to study medicine at Strasburg, where he became acquainted with Goethe, who in his autobiography has given a fine analysis of his character. He operated for cataract with eminent success at Elberfeld, was professor of rural economy at Lautern (1778), Marburg (1787), and Heidelberg (1804), and at his death was a privy councillor of Baden. The best known of his writings is an autobiography, Sailing's Ju-gend, Junglingsjahre, Wanderschaft, Lehrjahre, hausliches Leben und Alter (published in three parts, 1777, 1789, and 1817), a curious work, containing many profound thoughts, and marked by an eccentric religious and moral enthusiasm. He wrote several allegorical and mystical tales, as the Geschichte des Herrn von Morgen-thau (1779), Geschichte Florentins von Fahlen-dorn (1781), Leben der Theodore von Linden (1783), Das Heimweh (1794), and Theobald, oder der Schwarmer (1797). In his autobiography he takes a sentimental delight in picturing his three successive wives, and love and marriage are treated with special enthusiasm in his romances. In his later works he appears as a ghost-seer and theosophist.

The most important of them are: Theorie der Geisterkunde (1808), and Apologie der Theorie der Geisterkunde (18097, full of marvellous but not carefully authenticated narratives; Scenen aus dem Geisterreich (1817), consisting of conversations in heaven, and inculcating a sort of worship of genius; and the poem Chrysaon, oder das goldene Zeitalter (1819), descriptive of the millennium. His various works were collected in 14 vols. (Stuttgart, 1838).
