Wallace L. Dow's enduring legacy is visible throughout Sioux Falls and across South Dakota. His distinctive structures, whether civic buildings or private residences, are beholden to no single architectural style. A New Hampshire native, Dow was brought to the Dakota Territory in the 1880s by Governor Nehemiah Ordway. Dow quickly established himself as the preeminent architect of the Dakota prairie, designing iconic structures like Sioux Falls Courthouse and the penitentiary, as well as many beautiful private residences. Using local Sioux quartzite, Dow's buildings gave the emerging Dakota Territory an identity. Yet the architect himself remains something of a mystery. Join author and Dow documentarian Jennifer Dumke as she uncovers Dow's story, recounting the life and work of a true Sioux Falls original who left his mark statewide.
