Amos Cooper Dayton (April 1, 1811 – June 11, 1865)[1]: 4 was an American physician, Baptist minister, author, editor and educator, perhaps best remembered for his religious novels of the late 1850s and his role in the Landmarkism movement.
By 1839 Dayton and his wife had moved to Mississippi, where they lived in Columbus and Vicksburg, while he had a practiced as a dentist.
"[1][page needed] His most serious novel, Theodosia Ernest, or, The Heroine of Faith, was published in 1856-1857 in two volumes.
[1][page needed] In 1857, R. B. C. Howell, a critic of Landmarkism, became pastor for a second tenure at First Baptist of Nashville, where he served until 1868.
In 1858, Dayton published Pedobaptist and Campbellite Immersions, a review of numerous Baptist writers on issues related to baptism.
But, the 20th-century theologian J. E. Tull concluded that Dayton's 1858 book was "the most cogent attack upon 'alien immersions' which the Landmark movement produced.
