William Carter (7 December 1838 – 1917)[1] was an English composer, conductor, and organist.[2] He began a lengthy career as an organist at mainly churches in London at the age of nine. In 1859 and 1860 he spent one year in Canada as the organist at Cathedral of the Holy Trinity, Quebec, during which time he staged what was possibly the largest Handel Festival in Canada at that time. As a composer he is known for his liturgical anthems for chorus and organ, sacred works for organ, the oratorio Placida, the Christian Martyr (1872), and Cantata Domino in E (1891).[2] He founded and conducted the original choir at Royal Albert Hall, a group he led at that concert hall's grand opening in 1871.[2]
