William Horsley (18 November 177412 June 1858) was an English composer, organist and teacher.
Career
In 1790, Horsley became the pupil of the pianist and composer Theodore Smith (c. 1740–1810), who taught him sufficiently well to obtain the position of organist at Ely Chapel, Holborn, in 1794. He resigned this post in 1798 to become the organist at the Asylum for Female Orphans as well as the assistant to John Wall Callcott, with whom he had long been on terms of personal and artistic intimacy, and whose eldest daughter, Elizabeth Hutchins Callcott, he married. Callcott encouraged his interest in vocal music. In 1802 he became his friend's successor upon the latter's resignation. Besides holding this appointment he became the organist of Belgrave Chapel, Halkin Street, in 1812 and of London Charterhouse in 1838. More important are his glees, of which he published five books (1801–1807) besides contributing many detached glees and part songs to various collections. His glees include "By Celia's Arbour," "O, Nightingale," and "Now the storm begins to lower". His ballads, particularly Gentle Lyre and The Sailor’s Adieu enjoyed popularity in his lifetime. Two of his hymn tunes, 'Belgrave' (1819) and 'Horsley' (1844), the latter (usually set to There is a green hill far away), are still in use today. Their letters from that period are full of references to him, and were published in 1934. Fanny was an artist who died young, Sophie an accomplished pianist. Horsley's eldest daughter Mary Elizabeth (born 1813) married the engineer Isambard Kingdom Brunel. His son Charles Edward also enjoyed a certain reputation as a musician. Another son John Callcott was a painter, who is reputed to have designed the first Christmas card in 1843.
