"Framing the West" offers a comprehensive exploration of Timothy H. O’Sullivan’s work, a pivotal photographer of the American frontier. Trained by Mathew Brady, O’Sullivan accompanied significant government expeditions led by Clarence King in 1867 and George M. Wheeler in 1871. These expeditions resulted in unprecedented and complex visual depictions of the Western landscapes. The book serves as the first major analysis of O’Sullivan’s photography in over thirty years, featuring unpublished and rare images, arranged chronologically. It notes O’Sullivan’s influence on photography and is published in collaboration with the Smithsonian American Art Museum and the Library of Congress.
