History
Located in the area of South Dakota known as "East River" (east of the Missouri River, which diagonally divides the state), De Smet was platted by European Americans in 1880. It was named for Belgian Father Pierre De Smet, a 19th-century Jesuit missionary who worked with Native Americans in the United States and its territories for most of his life. In the mid-1880s, prairie fires and failures of crops after a three-year period of drought caused many settlers to relocate their farms and homesteads to easier areas. By 1917, De Smet was a cow town, with many trains passing through every day carrying cattle to market.

The Charles Ingalls family, originally of Wisconsin, arrived in De Smet in 1879. Their travels and pioneer life in Minnesota, Kansas, Dakota Territory, and Iowa would be later chronicled in the Little House series of books written by the Ingallses' second oldest daughter, Laura Elizabeth - later known as Laura Ingalls Wilder. Laura Ingalls and her husband Almanzo Wilder would first settle in De Smet along with Wilder's brother, Royal. They were later joined by their older sister, Eliza Jane, who took up a claim of her own. She was one of the first women who filed a claim on their own. There the Wilders lived just outside of De Smet on farmland, as well as Royal's feed store in town. the Ingallses also had a claim outside of town. In the winter they stayed in the town of De Smet, at least while the girls were still in school. After building a home and starting a farm there, Charles Ingalls helped to found the First Congregational Church of De Smet, later helping to build the church building, with the first service being held there on August 30, 1882. Ingalls and his wife, along with oldest daughter Mary, were among the church's eight original charter members.

Notable people
De Smet is the town where the family of author Laura Ingalls Wilder finally settled, and is the birthplace of Ingalls Wilder's daughter, author and activist Rose Wilder Lane. Ingalls Wilder's father, Charles Ingalls, moved to De Smet in 1879 with his wife, Caroline, and their children Mary, Laura, Carrie, and Grace. There, after first living in the Surveyor House and a couple of other locations in De Smet, Ingalls built their permanent home that became known via Wilder's writings as "The House That Pa Built".

Construction on the house began in 1887 and was completed in 1889. After settling in De Smet, Charles Ingalls owned and operated the Ingalls Store from 1880 to 1881, a small general-type store that sold various goods for the home. While the store building no longer exists, the location is noted in De Smet's downtown area with a marker on what's currently on the site, a former bank building that now houses Gass Law Firm.

De Smet was also the childhood home of supercentenarian Walter Breuning. Artist-illustrator Harvey Dunn was born in 1884 approximately eight miles from De Smet near Manchester, and painted scenes of frontier life in his later years. Harry George Armstrong, a major general in the United States Air Force, a physician, and an airman, was born in De Smet in 1899.
