Humphrey was born in West Simsbury, Hartford County, Connecticut (which became Canton, Connecticut) to farmer Solomon Humphrey, of a family that came from England before 1643, and Hannah, daughter of Captain John Brown.[5] His family moved to present-day Burlington, Connecticut at the age of six. He taught at local schools starting at age 15. He worked as a farm laborer for John Treadwell before entering university.[6]
Humphrey graduated from Yale University with an A.M. in 1805 and was ordained a Congregational minister on March 16, 1807. He became a minister in Fairfield, Connecticut, in 1807, moving to Pittsfield, Massachusetts, in 1817. His 1813 report to the Fairfield Association is one of the earliest temperance tracts published in America.[7] Humphrey is also said to have published six articles in The Panoplist and Missionary Magazine on the cause, origin, effects and remedy of intemperance.[8]
