David Humphreys Miller (June 8, 1918 – August 21, 1992) was an American artist, author, and film advisor who specialized in the culture of the northern Plains Indians.
In addition to his portraiture, he was also featured as a technical advisor on Native American culture for the films Cheyenne Autumn, How the West was Won, and the TV show Daniel Boone.
At age 16 with the aid of a translator, he first visited the Pine Ridge Indian Reservation in South Dakota and began interviewing the remaining survivors of the Battle of Little Bighorn, most of whom were over 70 years old.
A good friend of Korczak Ziolkowski, Miller organized the last reunion of the remaining 8 Bighorn survivors on June 3, 1948, at the dedication of the Crazy Horse Memorial.
Miller's most prominent and historically significant works were his 72 portraits of Custer survivors, which began with his painting of Chief Henry Oscar One Bull in 1935, and were completed in 1942.
