D. Michael Quinn played a key role in the foundation of “New Mormon History.” He was entrenched in the church archives during the “Camelot” years, taught at BYU, and published many ideas that represent positions held by the church today. Quinn was also part of the September Six, (in association with his 1993 excommunication), wrote about controversial issues, and provoked many love-hate relationships with his voluminous footnotes. In this interview, Patrick Mason explains some of Quinn’s contributions to Latter-day Saint history.
