is the managing editor for The Joseph Smith Papers. He received history degrees from the University of Utah, the University of Virginia, and Brigham Young University. From 1972 until 1980, he was part of the History Division of the LDS church’s Historical Department, with assignments both as a researcher and writer and as an archivist. He moved to Brigham Young University in 1980 when the History Division was transferred there to become the Joseph Fielding Smith Institute for Latter-day Saint History. From 1986 through 2002, he served as managing director of that research institute and as a professor of church history and doctrine. From 1988 to 1991, he served as one of the editors for Macmillan’s Encyclopedia of Mormonism. Most of his publications have involved Brigham Young and early Utah or pre-Utah Mormon history, including Men With A Mission: The Quorum of the Twelve Apostles in the British Isles, 1837–1841. Many of them also concern Joseph Smith and early Latter-day Saint leadership.
