The Turner-Cottman Building is an important retail and office building that represents the physical and commercial growth of downtown Casper. The building was designed by famed Wyoming architect Leon Goodrich in 1924 for Fred Cottman and Adah Turner-Cottman during a time of growth and expansion of Casper. The Cottmans achieved status in the area for developing a large sheep raising operation in the county. At the time of the building’s construction, Casper was rapidly growing due to expansion of the sheep industry and the rapid exploration and development of nearby oil fields. Casper became a center for shipping and oil field activities.
