Willard C. (Willard Carey) MacNaul

Willard C. MacNaul, identified in library and public-domain records as Willard C. (Willard Carey) MacNaul, born in 1864, is known for The Jefferson-Lemen Compact. The work was published by the University of Chicago Press in 1915 after being read before the Chicago Historical Society on February 16, 1915, and it focuses on the relationship between Thomas Jefferson and James Lemen in debates over slavery in Illinois and the Northwest Territory.

MacNaul presented the book as a documentary historical study rather than a sweeping popular narrative. In the prefatory note, he explains that the material was gathered while preparing a history of early Illinois Baptists and that he was publishing it in response to interest in the so-called Lemen family notes. That makes him especially interesting to readers who enjoy writers working close to original sources, archival questions, and contested pieces of American memory.

Little biographical information about MacNaul himself was easy to confirm from reliable publicly available sources beyond his name, birth year, and authorship of this work. Because of that, the surviving impression is mainly of a careful compiler and historical investigator whose reputation rests on this single, specialized contribution to early Illinois and antislavery history.
