Herzl was beyond question the most influential Jewish personality of the 19th century. He had no profound insight into the problem of Judaism, and there was no lasting validity in his view that the problem--the thousands of years' old mystery--could be solved by a retrogression to local nationality. But he brought home to Jews the perils that confronted them; he compelled many a "semi-detached" son of Israel to rejoin the camp; he forced the "assimilationists" to realize their position and to define it; his scheme gave a new impulse to "Jewish culture," including the popularization of Hebrew as a living speech; and he effectively roused Jews all the world over to an earnest and vital interest in their present and their future. Herzl thus left an indelible mark on his time, and his renown is assured whatever be the fate in store for the political Zionism which he founded and for which he gave his life. (I. A.) HERZOG, HANS (1819-1894), Swiss general, was born at Aarau. He became a Swiss artillery lieutenant in 1840, and then spent six years in travelling (visiting England among other countries), before he became a partner in his father's business in 1846. In 1847 he saw his first active service (as artillery captain) in the short Swiss _Sonderbund_ war. In 1860 he abandoned mercantile pursuits for a purely military career, becoming colonel and inspector-general of the Swiss artillery. In 1870 he was commander-in-chief of the Swiss army, which guarded the Swiss frontier, in the Jura, during the Franco-German War, and in February 1871, as such, concluded the Convention of Verrieres with General Clinchant for the disarming and the interning of the remains of Bourbaki's army, when it took refuge in Switzerland. In 1875 he became the commander-in-chief of the Swiss artillery, which he did much to reorganize, helping also in the re-organization of the other branches of the Swiss army. He died in 1894 at his native town of Aarau. (W. A. B. C.) HERZOG, JOHANN JAKOB (1805-1882), German Protestant theologian, was born at Basel on the 12th of September 1805. He studied at Basel and Berlin, and eventually (1854) settled at Erlangen as professor of church history. He died there on the 30th of September 1882, having retired in 1877. His most noteworthy achievement was the publication of the _Realencyklopadie fur protestantische Theologie und Kirche_ (1853-1868, 22 vols.), of which he undertook a new edition with G. L. Plitt (1836-1880) in 1877, and after Plitt's death with Albert Hauck (b. 1845). Hauck began the publication of the third edition in 1896 (completed in 22 vols., 1909). His other works include _Joh. Calvin_ (1843), _Leben Okolampads_ (1843), _Die romanischen Waldenser_ (1853), _Abriss der gesamten Kirchengeschichte_ (3 vols., 1876-1882, 2nd ed., G. Koffmane, Leipzig, 1890-1892).
