Sherman and Grace Coolidge were a remarkable couple in many respects. Sherman Coolidge (Runs On Top), born in the early 1860s into the Northern band of Arapahos, experienced the extreme violence of the Indian Wars, including the death of his father, as a young boy. Grace Wetherbee Coolidge was born into wealth and privilege in 1873, only to reject her life as a New York heiress and become a missionary on the Wind River Reservation in Wyoming. It was there that Sherman and Grace met and later married in 1902. After eight years together at Wind River, both went on to achieve prominence: Sherman as the president of the Native-run reform group the Society of American Indians (1911-1923), Grace as the author of Teepee Neighbors, a book describing her time on the reservation that drew praise from critics such as H. L. Mencken. Sherman was an Episcopal priest and a mesmerizing speaker who had the unique ability to blend his assimilated Western perspective with Arapaho values to educate the American public about the significant challenges facing Native peoples, including endemic poverty, racism, and inequality. Offering unprecedented entree into the most significant writings and documents of a leading Native American advocate and his wife, this volume is an intimate portrait of their life and contributes to our understanding of American Indian activism at a key moment of Indigenous resurgence against the settler state.
