“ KLOPP, ONNO (1822–1903) , German historian, was born at Leer on the 9th of October 1822, and was educated at the universities of Bonn, Berlin and Göttingen. For a few years he was a teacher at Leer and at Osnabrück; but in 1858 he settled at Hanover, where he became intimate with King George V., who made him his Archivrat. Thoroughly disliking Prussia, he was in hearty accord with George in resisting her aggressive policy; and after the annexation of Hanover in 1866 he accompanied the exiled king to Hietzing. He became a Roman Catholic in 1874. ”
