Dennis B. Horne grew up in south Davis County and he served in the Independence Missouri mission. He attended BYU and Weber State Universities, earning a degree in Communications. After working in television broadcasting for a number of years he became a technical writer for the LDS Church Material Management Department. He became an independent researcher/author because of his love of church history and doctrine. This pursuit led him to write a biography of Elder Bruce R. McConkie, an edited publication of the diaries of Abraham H. Cannon, and biographies of President Lorenzo Snow and Orson F. Whitney. He also wrote about callings to serve in the church, the doctrine of giving healing blessings, and a compilation of the teachings of prophets and apostles about how to determine doctrinal authority. He has twice presented at the BYU Church History Symposium. His articles occasionally appear at "truth will prevail," "Interpreter," and "FAIRMormon."
