The great popularity which Arthur Seymour Sullivan has enjoyed for a few years past, growing out of his extraordinarily successful series of comic operettas, beginning with "The Sorcerer" (1877), which first caught the public fancy, and ending with "The Mikado" (1885), has almost overshadowed the permanent foundations upon which his reputation must rest; namely, his serious and sacred music. He was born in London, May 13, 1842. His father, a band-master and clarinet-player of distinction, intrusted his musical education at first to the Rev. Thomas Hilmore, master of the children of the Chapel Royal. He entered the Chapel in 1854 and remained there three years, and also studied in the Royal Academy of Music under Goss and Sterndale Bennett during this period, leaving the latter institution in 1858, in which year he went to Leipsic. He remained in the Conservatory there until 1861, when he returned to London and introduced himself to its musical public with his music to Shakspeare's "Tempest," which made a great success. The enthusiasm with which this was received and the favors he gained at the hands of Chorley, at that time musical critic of the "Athenaeum," gave him a secure footing. The cantata "Kenilworth," written for the Birmingham Festival, the music to the ballet "L'Ile enchantee," and an opera, "The Sapphire Necklace," were produced in 1864. In 1866 appeared his first symphony, which has been played not only in England, but also in Germany, and an overture, "In Memoriam,"--a tribute to his father, who died that year. The next year his overture "Marmion" was first performed. In 1869 he wrote his first oratorio, "The Prodigal Son," in 1873 "The Light of the World," and in 1880 "The Martyr of Antioch;" the first for the Worcester, the second for the Birmingham, and the third for the Leeds festivals. The beautiful "Overture di Ballo," so frequently played in this country by the Thomas orchestra, was written for Birmingham in 1870, and the next year appeared his brilliant cantata "On Shore and Sea." On the 11th of May, 1867, was first heard in public his little comic operetta "Cox and Box." It was the first in that series of extraordinary successes, really dating from "The Sorcerer," which are almost without parallel in the operatic world, and which have made his name and that of his collaborator, Gilbert, household words. He has done much for sacred as well as for secular music. In addition to his oratorios he has written numerous anthems, forty-seven hymn-tunes, two Te Deums, several carols, part-songs, and choruses, and in 1872 edited the collection of "Church Hymns with Tunes" for the Christian Knowledge Society. He received the honorary degree of Doctor of Music from Cambridge in 1876, and from Oxford in 1879, and in 1883 was knighted by the Queen. The Prodigal Son.
