Klefeker, Bernhard a German preacher of distinction, was born at Hamburg Jan. 12, 1760, and was educated at Leipzig University, which he entered in 1779, and where, under the instruction of that eminent German pulpit orator Zollikoffer, he laid the foundation for his future excellency as a preacher. In May, 1791, he was called as regular preacher to Osnabruck, and, after a stay of five years, removed thence to his native city to assume the pastorate of St. James's Church. Here he labored with great acceptance and success until his death, June 10,1825. Though Kefeker aimed to be eminently successful in the pulpit, his literary efforts betoken a mind of rare activity. He published, besides several works on practical religion and his Sermons, a homiletical magazine (Homiletisches Ideenmagazin, 180919, 8 vols. 8vo): — Praktische Vorlesungen i. das N. Test. (1811-12, 3 vols. 8vo). See Doring, Deutsche Kanzelredner, p. 158 sq.
