HAUG, JOHANN HEINRICH: German mystic; d. at Berleburg (28 m. sx.e. of Arnsberg), West phalia, 1753. He first appears at Strasburg, where he received his master's degree, and was expelled from the city by the church authorities for holding a conventicle of Philadelphians (see Lead, Jane) and other mystic Separatists. Later he found refuge in the castle of Count Casimir at Berleburg, where he remained till his death, directing a Philadelphian organization that extended throughout western Germany. In 1730 Count Zinzendorf visited Berleburg and sought to unify the diverse elements that Haug had brought together; but after a few years the new organization fell to pieces and Haug and other Separatists reverted to their former customs. Haug believed that ultimately all things would be restored, and that Christ would reign on earth for a thousand years. In the interest of mysticism he made the revision of the Bible known as the Berleburg Bible (see Bibles, Annotated, I., § 3). He is said to have been a man of great piety and charming personality, and was regarded by Count Casimir as a prophet of God.
