Johann Karl Ludwig Gieseler

1792-1854. German Protestant church historian. Born in Petershagen in Westphal, he was educated at Halle, and in 1819 was called to a chair of theology at the University of Bonn, where he became a colleague of K.I. Nitzsch.* His earliest book, Historisch-kritischer Versuch über die Entstehung der Evangelien (1818), attempted to examine the oral tradition on which the synoptic gospels are based. In 1831 he was appointed professor of church history and doctrine at the University of Göttingen, succeeding G.J. Planck. Gieseler was co-founder of the journal of the Vermittlungstheologie, the Theologische Studien und Kritiken (1828). His most important publication was his Lehrbuch der Kirchengeschichte (5 vols., 1824-57), valued by Hase and Bauer for its rich documentation.
