The collection consists of correspondence (1914-1916) between Henry L. Loucks and Richard F. Pettigrew during 1914-1916. R. F. Pettigrew was a lawyer, surveyor, and land developer. He represented the Dakota Territory in the U.S. Congress and was a U.S. Senator from South Dakota after the Dakotas were admitted as states. H.L. Loucks was an economist and a Populist candidate for Governor of South Dakota in 1890. The collection is mainly political in nature, dealing with issues of the Progressive movement in the United States in the early 1900s.
