Paulus Stephanas Selig Cassel, a German clergyman and author, born of Jewish parentage in Glogau, Silesia, Feb. 27, 1827. He was educated in both the Roman Catholic and Protestant gymnasia of Schweidnitz, completed his studies of history in Berlin under Ranke, became a journalist, and in 1855 a Protestant. Subsequently he was director of the royal library and secretary of the academy at Erfurt, the government giving him the title of professor. He removed to Berlin in 1859, and served in the Prussian chamber of deputies from 1866 to the end of 1867, when he declined a reelection to become minister of Christ church, which position he continues to hold (1873). His treatises on the history of Erfurt were followed in 18-48 by his Magyarische Alterthumer, and in 1851 by an extensive historical article on the Jews in Ersch and Gruber's cyclopaedia, and a political disquisition, Von Warschau bis Olmutz, which attracted much attention. He has written also on various literary subjects; and his more important theological works are Weihnachten (1802), Die Backer der Richter und Ruth (1865), Sunam (1809), and Das Erangelium des Sohnes Zebeddi (1870). His works for the young have passed through numerous editions, and he has also acquired eminence as a lecturer on the oecumenical council and papal history (1809-'70), and on the Franco-German war.
