William Henry Monk (16 March 1823 – 1 March 1889) was an English organist, Anglican church musician, and music editor who composed popular hymn tunes, including “Eventide”, used for the hymn “Abide with Me”, and “All Things Bright and Beautiful”. Monk was born in Brompton, London, and studied music under several teachers. He served as organist and choirmaster at various churches and became choirmaster at King’s College London, where he developed an interest in plainchant. In 1852, he was appointed organist at St Matthias’ Church, Stoke Newington, where he arranged hymns and wrote his own melodies. In 1857, Monk became the musical editor of Hymns Ancient and Modern, a significant hymn book that included many of his compositions. He also taught vocal studies at King’s College and other music schools. Monk married Hope Pillow and had a daughter, Florence, who sadly died young. This loss inspired him to compose “Eventide”. Monk passed away in 1889 and is buried in Highgate Cemetery, London.
