Herschel, Sir William, English astronomer, born at Hanover, November 15, 1738, died at Slough, August 22, 1822. His father, Abraham, brought him up as a musician, and in that capacity he went to England in 1755, in the band of the Hanoverian guards, and for a considerable time earned his living as a teacher of music, obtaining a position as organist in Bath, in 1760. This seems to show, in all probability, that either he was baptized during this interval of five years in England, or that he was baptized in Germany. For as a professing Jew he would scarcely have ventured at that time to apply for the position of an organist, neither would his services have been accepted. He is known as the founder of Sidereal Science. His views on the position of the Solar System, in relation to the Milky Way, still form the central factor in the modern theory as to the constitution of the universe. He is also known as the discoverer of the infra-red solar rays.

Hershon, Paul Isaac, was born in Buczacz (Galicia) in 1818, where he received an excellent Hebrew and Talmudical education. Going to Jerusalem he came under the influence of Nicolayson, and was baptized by him. He then studied in the Jerusalem Missionary College from 1842 to 1846. Afterwards he was appointed principal of the House of Industry, and then from 1848-55 he laboured as missionary in England. Then he was appointed as head of the model farm at Jaffa, which office he resigned on account of illness in 1869, and returned to England. Henceforth he devoted himself to literary work, and wrote "Extracts from the Talmud," 1860; "The Pentateuch according to the Talmud," Hebrew, 1874; "A Talmudical Miscellany," 1880; "Treasures of the Talmud," 1882. He died in London, 1888.

Hertz, Henrik, Danish poet, born at Copenhagen, August 25, 1798; died there February 25, 1870. He embraced Christianity in 1832. His dramatic works alone comprise eighteen volumes and were published in 1854-73.

Heynemann. From this family in Saxony, whose head was Court Commissioner, no less than nine persons embraced the Protestant faith about 1749.

Hieronomy, David, baptized with his wife and six children in 1676, was nominated by the King Friedrich of Prussia as Inspector of the Synagogue. He had to suffer martyrdom.

Hirsch, Rev. David Jacoby, was born in 1820 at Sandersleben, in the Duchy of Anhalt. His parents were strict Jews. He received his early education at a school in Dessau. When he was a young man he came over to England, and in 1844 got to know the late Dr. Marsh, who first spoke to him of Christ. This led him to study the Word of God, and to enquire how he, a sinner, could be saved. Subsequently, Dr. Baylee, of Birkenhead, took a great interest in him, as he taught his boys German, French, Latin, and Hebrew. From him he received instruction in the Christian faith, and at the end of 1845 was baptized by him, and married his daughter. Later on he was ordained by Bishop Sumner for the German pastorhood at Liverpool, a post he filled until 1852, when he added to his pastoral duties missionary work among the Jews, receiving a grant from the Society for twelve years. He then retired until his death, in 1898, greatly missed by all who knew him.

Hirsch, Paul Wilhelm, was baptized in 1692, taught Hebrew, and issued a pamphlet in Berlin, 1717, under the title "Entdeckung der Tekuphath," in which he exposes the superstition held by rabbinic Jews, and then published in the calendar, that at the entrance of each of the four seasons of the year the fluid of the vessels containing water is turned into blood. This superstition has probably done them much harm.

Hirsch, Siegfried, born in 1816, studied history under the celebrated historian Ranke. Through the influence of Neander he became a devoted Christian. In 1844 he was appointed professor of history in the University of Berlin, where he was esteemed and beloved by the students. He was one of the founders of the conservative paper "Kreuz Zeitung." He died in 1860.

Hirsch, Theodor, born 1806 in Altschottland, near Danzig, embraced Christianity through the influence of Schleiermacher. He too became professor of history, first at Danzig, and later, in 1865, at Greifswald. In spite of his great learning, it is recorded that he was a very quiet and humble man. He died in 1881.

Hoga, Stanislaus, a native of Casimir, Russia, was, after embracing Christianity, a missionary of L.J.S. in London. He was mostly engaged in literary work, and translated "Songs of Zion," a selection of English and German Hymns, into Hebrew (1834—with additions, 1842); a translation of McCaul's "Old Paths" into Hebrew; "Nethivoth Olam," 1851; a Hebrew grammar of the English language, 1840; "The Controversy of Zion," a meditation on Judaism and Christianity, 1845; "Halichoth Orah," which is a translation of Bunyan's "Pilgrim's Progress"; "Eldad and Medad," which is a dialogue contrasting the New Testament and the Talmud; "Malakh Haberith," a translation of the tract "Angel of the Covenant." He also, together with Reichardt, revised the old edition of the Hebrew New Testament.
