The 8,000-square-foot Montminy Art Gallery was made possible by the generous gift of the estate of Tracy and Pierre Montminy and donations from county trusts, businesses, and individuals. Tracy and her husband, Pierre, were art professors at the University of Missouri-Columbia and Stephens College respectively. Their paintings are curated and regularly exhibited in the gallery, as is the work of local artists relevant to the Boone County community.
The Society also curates and exhibits the work of nine Boone County photographers, work spanning more than a century that includes more than 700,000 photographic glass plate and acetate negatives. The collection depicts people and life in Boone County from 1867 through the mid-twentieth century.
