 HEREDIA

HERTZOGENBERG

a Spencerian Agnostic (see, especially, his articles in the Nineteenth Century, Aug. and Sep., 1901), and he ably supported Bradlaugh, and pressed for secular educa tion and other reforms. D. Nov. 5, 1906.

HEREDIA, Jose Maria de, French poet. B. (in Cuba, of French mother) Nov. 22, 1842. Ed. Paris, and Havana University. He settled in Paris, adopted French nationality, and studied law, but he turned to letters and published his first poems in 1862. His exquisite sonnets in the Parnasse Contemporain and elsewhere gave him a high position in his art, but he cared so little for publicity that he issued only one volume, Les Trophees (1893, Eng. trans., 1897). He was a member of the Academy. Heredia was an enthusiastic admirer of the Rationalist poets Chenier, Hugo, and Leconte de Lisle, and shared their creed. D. Oct. 3, 1905.

HERTWIG, Professor Oscar, M.D.,

Ph.D., German anatomist. B. Apr. 21, 1849. Ed. Miilhausen Gymnasium, and Jena, Zurich, and Bonn Universities. He was appointed teacher of anatomy and em bryology at Jena in 1875 and professor in 1878. In 1888 he became Director of the Berlin Institute of Anatomy and Biology, and professor of general anatomy and em bryology at the University. Hertwig is a member of the Royal Academy of Science, Privy Councillor, and joint editor of the Archiv filr mikroskopische Anatomic und Entivickelungsgeschichte. His works on embryology and biology have won for him membership of the French Societe de Biologie, the Linnsean Society, the Royal Microscopic Society, the Boston Society of Natural History, and a dozen others. Professor Breitenbach enumerates Pro fessor Hertwig among the pupils of Haeckel who have been faithful to his teaching (Was Wir E. Haeckel Verdanken, 1914, i, 209).

He is a Privy Councillor and the author of many important works (including some of the Challenger series). In the Haeckel Memorial Volume (Was Wir E. Haeckel Verdanken, 1914) Professor Hertwig has a fine appreciation of his old master and his life-work (ii, 165-70).

HERTZEN, Alexandr Ivanovich,

Russian writer. B. Mar. 25, 1812. Ed. Moscow University. Although he was a son of Prince Jakovlev, he joined a Saint- Simonian society in his youth and was imprisoned. He then entered the govern ment service, but left it in 1842 to engage in the study of philosophy and letters, and, further developing his advanced opinions, he was banished from Russia in 1846. From London, where he set up a press in 1851, and later from Switzerland, he issued a periodical, the Kolokol (Bell), which had an immense power in Russia. Hertzen was rich and cultivated, and many of his works (published in 10 vols. in 1875) embody his very drastic Rationalism. D. Jan. 21, 1870.

HERTZOGENBERG, Heinrich von,

Austrian musical composer. B. June 10, 1843. Ed. Vienna Conservatorium. He settled at Leipzig, where he founded a Bach Society, and in 1885 was appointed professor of composition at the Berlin Royal High School of Music. He wrote some fine chamber and choral pieces. He was an intimate friend of Brahms, and their correspondence shows that Hertzo- genberg, who was brought up a Catholic, became as Rationalistic as Brahms. I believe nothing,&quot; he wrote near the end of his life (Letters of J. Brahms : the Hertzo- genberg Correspondence, 1909, p. 416). Hertzogenberg was joint editor of an ecclesiastical musical paper (Monatsschrift 342
