“This is the first time so much personal information about a Native American and his Anglo-American wife has been exposed in such depth and insight. Sherman Coolidge’s bold leadership in the 1910s called attention to the prejudice and abject ignorance of American people. There is no doubt that Lewandowski’s valuable work will be a lasting legacy to the Arapaho Nation, Euro Americans, U.S. history, and other Indian nations. Part of Coolidge’s papers should be incorporated into every American history textbook.”-Rowena McClinton, editor of John Howard Payne Papers: Volumes 7–14 of the Payne-Butrick Papers “Lewandowski’s book serves as an important contribution to the field [in] its singular focus, its author-centrism, and its rigorous deployment of careful archival work and assemblage. This volume reveals Coolidge’s rhetorical tactics and his deft maneuvering of U.S. government policy concerning tribes, the impetus to convert Native people to Christianity that is at the core of his religiosity, and his growing circumspection regarding assimilationism, national pan-tribal organizations, the Indian Bureau, ‘civilization’ versus ‘traditionalism,’ and more.”-Julianne Newmark, author of The Pluralist Imagination from East to West in American Literature
