Hutter, Leonhard a German Lutheran theologian, was born at Nellingen, near Ulm, in January, 1563, studied philosophy, philology, and theology at Strasburg, Leipzig, Heidelberg, and Jena; became private tutor in the latter university in 1594, and in 1596 professor at Wittenberg, where he died, Oct. 23,1616. He was a zealous upholder-of Lutheran orthodoxy. His Conpendium locorum theologicorum (Wittenb. 1610, etc.), prepared by order of the elector Christian, took the place of Melancthon's Loci as a text-book, and was translated into several languages (into German by Holstenius [Lib. 1611], and by Hutter himself [1613, etc.] into Swedish [Stock. 1618]), and commented on by Cundisius (Jena, 1648, etc.), Glassius (1656), Chemnitz (1670), Lachmann (1690), etc. It has lately been reproduced by Hase under the title fitterus redivivus (Berl. 1854), and translated into English, under the title of Compend of Lutheran Theology, by the Rev. H. E. Jacobs and the Rev. G. F. Spieker (Phila. 1868, 8vo). He carried out the Compendiun further in his Loci communes theolog. (Wittenb. 1619, fol., etc.). He also wrote against John Sigismund of Brandenburg, who had embraced Calvinism, his Callvinista aulico-politicus (Wittenb. 1609-14, 2 vols.),-and against Hospinian's Concordia discors another work, entitled Concordia concors (Wittenb. 1614). His other writings are De Voluntate Dei circa ceternum praedestinationis salvandoraum Decretum (Wittenb. 1605, 4to): — Explicatio libri Christiane concordantiae (Wittenberg, 1608. 8vo; twice reprinted): — Irenicum vere Christianum, sire tractatus de synodo et unione evangelicorum non fucata concilianda (Rost. 1616, 4to; 1619, folio), against the plan of fusion between the Lutheran and Reformed churches of Pareus, and especially against the latter's Irenicum.
