John R. Champlin (1836-1896) was born in Lebanon, Connecticut, and died in Norwich, Connecticut. He was a farmer until 1864 when he moved to South Willington, Connecticut, and started a textile manufacturing business with his brother-in-law, Gardiner Hall Jr. He became interested in Christian Science in early 1886, writing to Mary Baker Eddy to purchase a copy of Science and Health with Key to the Scriptures.
