CHEMNITZ or KEMNITZ, MARTIN (1522-1586), Ger man Lutheran theologian, was born at Treuenibrietzen, Branden burg, on Nov. 9, 1522, and died in Brunswick on April 8, 1586. Educated at Magdeburg (1539-42) and at the universities of Frank furt-on-Oder and Wittenberg (1545), Chemnitz became interested in mathematics and astrology, and in 1547 Melanchthon gave him an introduction to Georg Sabinus at Konigsberg, where he was made rector of the Kneiphof school in 1548. In 155o Duke Albert of Prussia made him his librarian and he turned his atten tion to biblical studies. In a controversy with Osiander, on justifi cation by faith, Chemnitz defended the Lutheran doctrine of impu tation. In 1553 he returned to Wittenberg and gave lectures on Melanchthon's Loci Communes, which formed the basis of his own Loci Theologici (published posthumously in 1591), an expo sition of Lutheran theology as modified by Melanchthon. Chemnitz also wrote Repetitio same doctrinae de Vera Praesentia in German, 156i ) in support of the Lutheran view of the Euchar ist, against the Crypto-Calvinists; Theologiae Jesuitarum prae cipua capita (1562) ; and Examen concilii Tridentini (4 parts, 1565-73). In 1554 he moved to Brunswick, as coadjutor to the superintendent, Joachim Morlin, and in conjunction with him drew up his Corpus doctrinae Prutenicum (1567). In conjunction with Andrea and Selnecker he induced the Lutherans of Saxony and Swabia to unite in adopting the Formula Concordiae.
