John Tanner was a leading figure in the early days of the Latter-day Saint movement, and a chief financial backer of the Kirtland Temple. Tanner was a native of Rhode Island. He moved to New York when fairly young. Of his 21 children from three successive wives, 14 lived to adulthood. Tanner was a Baptist until he joined The Church of Jesus Christ of Latter Day Saints in 1832. He was baptized by Jared Carter. Ten of his 14 children who lived to adulthood affiliated with The Church of Jesus Christ of Latter-day Saints and eventually moved to Utah Territory. In late 1834, Tanner sold his property in and around Lake George, New York which included a hotel. He then moved to Kirtland, Ohio where in early 1835 he lent money and assumed loans to keep the building of the Kirtland Temple moving forward. When Joseph Smith tried to repay him he refused any payment saying they owed him nothing. Tanner moved with the main body of the Church to Missouri, where he was on one occasion attacked as a result of mob and government persecution that led to the Saints fleeing the state. He then moved to Montrose, Iowa where he lived for six years. He then moved for a time to Nauvoo, Illinois. Tanner eventually went west with the pioneers. He led the large family of his son-in-law Amasa Lyman west, since Lyman was in the advanced pioneer company. Two of Tanner's sons were in the Mormon Battalion. He settled in Cottonwood, Utah Territory where he died in 1850.
