[NATIVE AMERICANS]. [NOTCHININGA (?No Heart?)]. Cabinet photograph of Sioux chief ?No Heart?s? three children. Mandan, Dakota Territory: R. Gilbert, n.d. [ca. 1880]. On original studio mount (overall, 165 x 108 mm), early printed caption mounted on verso. No Heart was a leader of the Iowa people and served in Iowa?s delegation to an inter-tribal congress in Washington, D.C. which aimed to settle boundary disputes between the Santee Sioux and their rivals the Sauk and Meskwaki peoples. No Heart was also a notable map maker who followed the same conventions as maps produced by Euro-American cartographers and was able to produce detailed maps of the Missouri valley showing legitimacy of Iowa claims. His three children, according to the caption on the verso, ?pride[ed] themselves on being the best looking Sioux in the Sioux tribe?.
