Daniel Sedgwick (1814–1879), hymnologist, was born in London. After his marriage in 1839, he joined the Strict Baptist congregation at Providence Chapel, Grosvenor Street, Commercial Road, and later opened a bookshop at 81 Sun Street, Bishopsgate. In 1859 he began republishing old collections of hymns, under the general title Library of Spiritual Song, which led to A Comprehensive Index of Many of the Original Authors and Translators of Psalms and Hymns (1860), which placed him at that time (pre-Julian) as the leading hymnologist in England. Spurgeon and Josiah Miller consulted him, and Julian relied on his manuscripts.
