(1791–1860), German diplomatist and amateur theologian. From 1823 to 1839 he was minister at the Prussian legation at Rome, where he proved himself a masterly diplomat and settled delicate matters connected with the relations between Germany and the Holy See. After two years as minister at Berne, he held the same office in London from 1841 to 1854. Here he was regarded as the most distinguished representative of European Protestantism in England and was the chief instrument in the scheme for a joint Lutheran and Anglican bishopric in Jerusalem. His voluminous and verbose theological writings, for the most part of little enduring value, include a treatise on the Epp. of St Ignatius (1874); Hippolytus and his Age (4 vols., 1852); Christianity and Mankind (7 vols., 1855, an English version of some earlier writings, then first published as one work); Gott in der Geschichte (3 vols., 1857–8; Eng. tr., 1868–70); and Vollständiges Bibelwerk für die Gemeinde (9 vols., 1858–70).
