Pierre Dorian was the first white settler in the Yankton area. He lived among the Yankton Sioux at the time that Lewis and Clark passed through in 1804. Lewis and Clark convinced Dorian to accompany them on their expedition and to serve as an Indian interpreter. Dorian later returned to the Yankton area. His grave was located by a local historian and a memorial marker dedicated in 2002.
