Thou wilt keep him in perfect peace, Samuel Sebastian Wesley

Samuel Sebastian Wesley (14 August (also my birthday)1810 – 19 April 1876) was an English organist and composer. Wesley married Mary Anne Merewether and had 6 children.[1] He is often referred to as S.S. Wesley to avoid confusion with his father Samuel Wesley.

Famous in his lifetime as one of his country's leading organists and choirmasters, he composed almost exclusively for the Church of England, which continues to cherish his memory. His better-known anthems include Thou wilt keep him in perfect peace and Wash me throughly. He also wrote several rather late examples of verse anthems, which contrast unison and contrapuntal sections with smaller, more intimate passages for solo voice or voices. Blessed be the God and Father, The Wilderness and Ascribe unto the Lord are of considerable length, as is his Service in E.

The popular short anthem Lead me, Lord is an extract from Praise the Lord, O my soul. Several of his pieces for solo organ have enduring value and continue to be played in recitals now and then.

Of his hymn tunes the best-known are "Aurelia" and "Hereford." "Aurelia" has been widely adopted in the United States, and is regularly heard there. Usually now sung to the words "The Church's One Foundation", Wesley composed the tune for the hymn "Jerusalem the Golden", hence the name "Aurelia".[6]
