Deloria was a Standing Rock Sioux who published "Custer Died for Your Sins" in 1969 and later amplified his message through 20 more books about the Native American experience. Deloria, who was trained as both a seminarian and a lawyer, steadfastly worked to demythologize how white Americans thought of American Indians. The myths, he often said - whether as romantic symbols of life in harmony with nature or as political bludgeons in fostering guilt - were both shallow. The truth, he said, was a mix, and only in understanding that mix, he argued, could either side ever fully heal. -- New York Times Obituaries, November 15, 2005.
