Johann Jakob Herzog (12 September 1805 – 30 September 1882) was a Swiss-German Protestant theologian.
Herzog was born in Basel. Herzog studied theology at the University of Basel and Berlin, earning his doctorate at the University of Basel in 1830. In 1835-1846 he was a professor of historical theology at the Academy in Lausanne. Afterwards he served as a professor in Halle, and eventually (1854), he settled at Erlangen as a professor of church history.[1]
Herzog is remembered for his writings on the history of the Reformation (Zwingli, John Calvin, Johannes Oecolampadius), and for his studies of the Waldensian Church.[1]
Herzog was author of the "Real-Encyklopädie für protestantische Theologie und Kirche" (1853–1868, 22 volumes), of which a new edition, in collaboration with Gustav Leopold Plitt and Albert Hauck, was published from 1877 to 1888 (18 volumes). From 1896 to 1913, Hauck released a third edition of the encyclopedia (24 volumes; Vol 1–22, 1896–1909, with two later supplements).[2] [3] Based on the encyclopedia's third edition, the New Schaff-Herzog Encyclopedia of Religious Knowledge was subsequently published in English from 1908 to 1914 (13 volumes).[4] He died in Erlangen.
