The series, established by one of the twentieth-century West's most distinguished historians, Leonard Arrington, has become a leading forum for prominent historians to address topics related to Mormon history. The first lecturer was Arrington himself. He was followed by Richard Lyman Bushman, Richard E. Bennett, Howard R. Lamar, Claudia L. Bushman, Kenneth W. Godfrey, Jan Shipps, Donald Worster, Laurel Thatcher Ulrich, and F. Ross Peterson. Utah State University hosts the Leonard J. Arrington Mormon History Lecture Series. The University Libraries' Special Collections and Archives houses the Arrington collection. The state's land grant university began collecting records very early, and in the 1960s became a major depository for Utah and Mormon records. Leonard and his wife Grace joined the USU faculty and family in 1946, and the Arringtons and their colleagues worked to collect original diaries, journals, letters, and photographs.

Although trained as an economist at the University of North Carolina, Arrington became a Mormon historian of international repute. Working with numerous colleagues, the Twin Falls, Idaho, native produced the classic Great Basin Kingdom: An Economic History of the Latter-day Saints in 1958. Utilizing available collections at USU, Arrington embarked on a prolific publishing and editing career. He and his close ally, Dr. S. George Ellsworth helped organize the Western History Association, and they created the Western Historical Quarterly as the scholarly voice of the WHA. While serving with Ellsworth as editor of the new journal, Arr ington also helped both the Mormon History Association and the independent journal Dialogue get established.
