William Bengo Collyer (1782-1854) was an English Congregational minister, hymn writer, theologian, and popular evangelical preacher. He was born at Blackheath, England, on April 14, 1782. At the age of sixteen, he entered Homerton College to prepare for the ministry. He began his pastoral work at Peckham on December 17, 1801, when he was only nineteen years old. His congregation was initially a small church consisting of just ten communicants. Collyer continued serving the Peckham congregation throughout his ministry, becoming widely respected for his preaching and pastoral work. He received the degree of Doctor of Divinity from the University of Edinburgh in 1808. From 1814 to 1826, he also served a church meeting at Salters' Hall. A new chapel for his Peckham congregation was opened on June 17, 1817, reflecting the growth and success of his ministry. He preached his final sermon on December 11, 1853, and died on January 8, 1854.

Collyer was regarded as one of the most popular Dissenting ministers in London during his lifetime. He was particularly known for his eloquent evangelical preaching at a time when formalism in worship and Arianism in doctrine were significant concerns within religious life. Contemporary accounts describe him as a man of amiable disposition, polished manners, and Christian courtesy, whose ministry attracted both wealthy and poor hearers. Beyond preaching, he was a substantial theological writer. His seven-volume series on Divine Revelation covered Scripture facts, prophecies, miracles, parables, doctrines, duties, and comparisons. He also published Services suited to the Solemnization of Matrimony, Baptism, and other occasions in 1837. His interest in Christian ministry extended to missionary and benevolent work, and several of his hymns were prepared for public meetings of missionary and charitable societies.

Collyer's principal contribution to hymnody was his collection Hymns partly collected and partly original, designed as a supplement to Dr. Watts's Psalms and Hymns, published in 1812. Originally intended for use within his own congregation, the collection was eventually expanded to contain 979 hymns, six choruses, and four doxologies. It included 57 hymns written by Collyer himself, alongside works by other authors. The hymns were arranged according to their authors rather than by subject. His original compositions appeared in several other publications, including Hymns for Israel, a Tribute of Love for God's Ancient People (1848), which contained 41 hymns. Thirty-nine of his compositions were also included in Dr. Leifchild's Original Hymns (1843), while others appeared in the Evangelical Magazine and as appendices to his published sermons. His 1837 collection of religious services also included 89 of his hymns and related pieces.

Collyer's hymn writing covered a variety of subjects, including evening reflection, praise, the work of Christ, Christian worship, national calamity, and concern for the poor and vulnerable. His compositions included "Another Fleeting Day Is Gone," "Assembled at Thy Great Command," "O Jesus, in This Solemn Hour," "O Thou, the Helpless Orphan's Hope," "Return, O Wanderer, Return," "See the Clouds upon the Mountain," "Soft Be the Gently Breathing Notes," "Softly the Shade of Evening Falls," and "Thou Prince of Glory Slain for Me." The hymn "O Thou, the Helpless Orphan's Hope" appeared in the Evangelical Magazine in 1808, while several others were published in his 1812 collection or in Leifchild's 1842 material. "Great God, What Do I See and Hear" is a well-known cento associated with his work. Although John Julian observed that many of Collyer's compositions were more like descriptive or moral poems than hymns addressed directly to God, he also recorded that several remained in common use. William Bengo Collyer is remembered in hymnological history for combining a long and influential pastoral ministry with extensive theological writing and a considerable contribution to early nineteenth-century English Congregational hymnody.
