Jerald and Sandra Tanner

Jerald Dee Tanner and Sandra McGee Tanner are American writers and researchers who publish archival and evidential materials about the history of the Church of Jesus Christ of Latter-day Saints. The Tanners founded the Utah Lighthouse Ministry (UTLM), whose stated mission is "to document problems with the claims of Mormonism and compare LDS doctrines with Christianity". As of 2025 Sandra Tanner continues to operate the ministry after Jerald's death in 2006. The physical Lighthouse Ministry bookstore closed in 2023.
