Abstract The Kent Logan Walgren papers (1739-2002) are comprised of Walgren's correspondence and notes, Masonic bibliographical works, materials concerning the relationship between Freemasonry and LDS theology, and LDS historical documents and studies. Kent Logan Walgren (1947-2003) became immersed in a multi-year investigation of Freemasonry which resulted in a 2002 publication of a two volume work titled "Freemasonry, Anti-Masonry and Illuminism in the United States, 1734-1850: A Bibliography."
