Andrew Jenson undertook a lifelong quest to render the LDS historical record complete and comprehensive. As Assistant Church Historian of the Church of Jesus Christ of Latter-day Saints, Jenson tirelessly carried out his office’s archival mission and advocated for fixed record keeping to become a duty for Latter-day Saints. Reid L. Neilson and Scott D. Marianno offer a new in-depth study of Jenson’s long life and career. Their account follows Jenson from his arrival as a Danish immigrant to 1860s Utah through trips around the world to secure documents from far-flung missions, and on to his public life as a newspaper columnist and interpreter of LDS history. Throughout, Jenson emerges as a figure dedicated to the belief that recorded history united past and present Latter-day Saints in heaven and on earth–and for all eternity.
