ISENMANN (more correctly Isenmenger or Eisenmenger), JOHANN: German reformer; b. at Schwäbisch Hall (35 m. n.e. of Stuttgart), Württemberg, c. 1495; d. at the monastery of Anhausen on the Brenz (near Heidenheim, in Württemberg, 20 m. n.n.e. of Ulm) Feb. 18, 1574. He studied at the University of Heidelberg in Apr., 1514, became dean of the classical faculty on Dec. 20, 1521; was called to Hall as pastor in the spring of 1524, and then wrought for twenty-four years with Brenz for the Reformation in that place. The festival of Corpus Christi was abolished in 1524; at Christmas, 1525, the Lords Supper was observed by Evangelical rite; and in 1526, an Evangelical liturgy was introduced. Isenmann took an eager part in the Syngramma Suevicum in 1525 (see BRENZ, JOHANN, § 2). He became superintendent in 1542. At the beginning of 1546 he reformed the imperial town of Wimpfen. Heavy tribulation ensued from the Schmalkald War, with the emperors triumphant entrance to Hall, Dec., 1546; and the situation grew sti1l more dangerous during the Interim, which both Isenmann and Brenz rejected. When the Spaniards came, the council had to dismiss Evangelical preachers. In July, 1549, Isenmann removed to Württemberg, and became preacher at Urach. Soon afterward he became pastor at Tübingen, and general superintendent of the southwest district. He enjoyed the confidence of the new duke. In 1551 he went with Jakob Beurlin (q.v.) to Langensalza and Leipsic to have the Württemberg Confession subscribed by Melanchthon and the theologians of Wittenberg and Leipsic. In the summer of 1557 he accompanied the duke to the diet at Frankfort, and collaborated in the great Apologia confessionis Wirtembergicae. In 1558 he was appointed abbot at Anhausen, where he spent the remainder of his life.
