Gottfried Christian Friedrich Lucke, a German theologian, born at Egeln, near Magdeburg, Aug. 23, 1792, died in Gottingen, Feb. 14, 1855. He studied at Halle and Gottingen, published De Ecclesia Apostolica (Gottingen, 1813), became in 1813 tutor in the theological faculty of Gottingen, and in 1816 went as Privatdocent to Berlin. In 1818 he accepted a call to the new university of Bonn; but in 1827 he returned to Gottingen as ordinary professor. His two most important works are Grundriss einer neutestamentliclien Her-meneutik (Gottingen, 1817), and Commentar uber die Schriften des Evangelisten Johannes (4 vols., Bonn, 1820-'32; 3d ed., the last volume revised by Bertheau, 1842-'56). The latter work, in particular, is still classed among the best exegetical productions of German theology. In Berlin, he edited with Schleier-macher and De Wette the Theologische Zeit-schrift; in Bonn, with Gieseler, the Christ-liche Zeitschrift. Afterward he was assistant editor of the Studien und Kritiken. His biographical essays on his teacher Planck (1835) and his friends Schleiermacher (1834) and De Wette (1850) are especially valued.
