Brookings County South Dakota

The county and the city of Brookings got their names from one of South Dakota’s greatest pioneer promoters, Wilmot W. Brookings. Brookings set out for Dakota Territory in June of 1857. He arrived at Sioux Falls on August 27, 1857, and became one of the first settlers there. He and his group represented the Western Town Company. After a time in Sioux Falls, Brookings and a companion set out for the Yankton area to locate a town in an area that was soon to be ceded by the Native Americans.
