Franz Delitzsch, a German theologian, born in Leipsic, Feb. 23, 1813. He studied at the university of his native city, and in 1846 was appointed professor of theology at Rostock. He removed in 1850 to Erlangen, where he became one of the strongest representatives of the so-called Erlangen school, which is an exponent of the strictest orthodox theology. His earliest publications were mostly studies in oriental philology, including Geschichte der judischen Poesie (Leipsic, 1836), and Jesurun (1838). He devoted himself subsequently to exegesis, and published Habakuk (Leipsic, 1843), Das Eohe-lied (1851), Lie Genesis (1852), Die Briefe an die Hebraer (1857), and Eiob (1864). His dogmatical work Das Sakrament des wahren Leibes und Blutes Jesu Christi (1844), and his System der biblisclieri Psycliologie (1855), have passed through numerous editions. His Handschrift-liche Funde (1861-'2) contains valuable critical remarks on the text of the Apocalypse. Since 1863 he has been engaged with Keil in preparing a complete commentary on the Old Testament; several volumes have appeared, and, like most of his works, have been translated and republished in Edinburgh. His latest production is Studien uber indo-germanisch-semitische Wurzelveruoandschaft (1873).
