During the late nineteenth and early twentieth centuries, Montana's Native American peoples received a surprising amount of attention from artists and photographers ... people who were presumably enchanted by the romance of the vanishing Indian lifestyle, and who hoped to document it in their own way before it was too late.
An intriguing but lesser-known person in this category was a woman named Olga Ross Hannon, an Midwestern transplant who taught art at the college in Bozeman from 1921 until her death in 1947. Hannon's paintings and other work explored a variety of Montana themes, including explorations of Native Native American art and culture. (Hannon Hall on the MSU campus is named for her.)
The evocative image below is credited to Hannon ... it's a portrait of a man named Joshua Spotted Dog, taken at Poplar on the Fort Peck Indian Reservation.
