Clarence W. Wigington
Clarence Wesley "Cap" Wigington (1883-1967) was an African-American architect who grew up in Omaha, Nebraska. After winning three first prizes in charcoal, pencil, and pen and ink at an art competition during the Trans-Mississippi Exposition in 1899, Wigington went on to become a renowned architect across the Midwestern United States. It was a time when there were few African-American architects in the entire United States. Wigington was the nation's first black municipal architect, serving as senior designer for the City of Saint Paul, Minnesota's architectural office for 34 years when the city had an ambitious building program. Sixty of his buildings still stand in Saint Paul, with several recognized on the National Register of Historic Places. His architectural legacy constitutes one of the most significant bodies of work by an African-American architect.
