Frederick Dupree was a French fur trader. He came to live near Fort Pierre in 1838. He married a Lakota woman. They had a large family. They became ranchers on the Cheyenne River. Frederick and his sons went to the last great buffalo hunt in 1883. They caught five buffalo calves and took them to their ranch. They turned them loose with the cattle for the winter. The buffalo grew up and stayed with the cattle.
