Brookings County [†], formed on April 5, 1862, received designation of its current-day boundaries in 1873. Six years later, in 1879, the Chicago and Northwestern Railroad Company laid tracks as far west as Volga, South Dakota, thus constructing the Dakota Central Branch. During that same year, the Chicago and Northwestern platted four other towns along its tracks in Brookings County, including Brookings.
The county was named for Wilmot Wood (W. W.) Brookings [1830-1905]. Brookings was the first provisional governor of the Dakota Territory.
