Sergeant I-See-O (born c. 1849) was a Kiowa who served as an Indian Scout from 1889 until his death in 1927. He served alongside future Army Chief of Staff Hugh L. Scott in the final campaigns of the Indian Wars. In 1915 Scott persuaded Congress to allow I-See-O to serve on active duty for life. I-See-O, who, according to Scott, "has simply been stunned by civilization", lived in a teepee in a remote part of Fort Sill, Oklahoma during his later days. He was a guest of President Calvin Coolidge at the White House in 1925.
