This week on Listening to America, Clay Jenkinson interviews professional photographers John and Coleen Graybill of Buena Vista, Colorado, about the life and achievement of Edward S. Curtis. Curtis took 40,000 dry glass plate photographs of Native Americans between 1900 and 1935, and published 20 volumes of his portraits, landscape photographs, musical notations, and a gigantic amount of ethnographic prose. John is the great great grandson of Edward Curtis. The Graybills are traveling the West photographing descendants of individuals that Curtis photographed, and interviewing them on video about their lives and their heritage. They have released two books of previously unpublished Curtis photographs. It's an amazing story of love, integrity, and perseverance.
