The Davidson Building
505 6th Street
Placed on the National Register of Historic Places on June 25, 1999
Designed by William L. Steele and constructed in 1913 at a cost of $450,000, the six story Davidson Building is the only structure in Sioux City designed exclusively in the important Chicago style. Its stunning Sullivanesque ornamentation features vertical bands of cream glazed stylized terra cotta foliage, lion heads and a gold “D” emblazoned under the windows on the 6th and Pierce Street sides. Tungsten lamps, placed under the ornamental cornice, give the building a spectacular glow at night. Ben Davidson, who emigrated from Russia to Sioux City in 1882, peddled tinware. One year later, a brother David followed, and the two opened a retail store. Their story is the American dream; ten years later, they were constructing this “office building for professionals.”
