Amos S. Hayden, born 1813, died 1880, was an American preacher, educator, and hymn composer whose work significantly shaped the Restoration Movement within the Disciples of Christ during the 19th century. Born on September 17, 1813, in Youngstown, Ohio, to Samuel and Sophia Hayden, he was the youngest of eight children in a Baptist family that had emigrated from Pennsylvania in 1803. Raised on a farm with limited formal schooling, Hayden was a self-driven learner, devouring religious texts like Hervey’s Meditations and Pilgrim’s Progress in his youth. Converted at age 14 in 1828 under the preaching of Walter Scott, a key Restoration figure, he was immersed and soon began exhorting, traveling with his brother William and holding meetings by age 19 that drew notable success. Hayden’s ministry flourished as he pastored in Collamer (then Euclid), Ohio, starting in 1840, and became the founding principal of the Western Reserve Eclectic Institute (later Hiram College) in 1850, leading it to prominence over seven years. He briefly served as principal of McNeely Normal School in Hopedale, Ohio, in 1858, before returning to Collamer, where he ministered for most of his remaining years. A gifted musician, he compiled the first Disciples hymnbook at 21 and later published The Sacred Melodeon, alongside contributing to the Christian Hymn Book. Married to Sarah M. Ely in 1837, with whom he had eight children, Hayden died on September 10, 1880, in Cleveland.
