Includes correspondence with noted photographers Ansel Adams, Edward Weston, and others; published and unpublished manuscripts by Nancy Newhall concerning Ansel Adams, such as Death Valley (l953), The Eloquent Light (l963), and "The Enduring Moment" (ca.1971); writings by Beaumont Newhall including Photography: Essays and Images (1980) and his revised and enlarged edition of The History of Photography (l98l); and printed materials relating to their wide interests. These papers represent one important segment of the personal papers of Nancy Newhall, and to a lesser extent those of Beaumont Newhall. These letters and writings were culled by Beaumont Newhall, and were sent to the Center after Nancy Newhall's death in 1974. They were intended to complement the archive of Ansel Adams which had already been committed to the Center. The bulk of the material in this collection relates to the career of Nancy Newhall and begins in the late 1930s and continues until her death in 1974; a lesser amount of material is present for Beaumont Newhall, especially his Photography: Essays and Images, and his final revision of The History of Photography. The general correspondence, 1942-1978, contains personal and business correspondence between the Newhalls and editors, publishers, artists, curators, museums and universities. Since the Newhalls worked together and often on similar topics, much of the personal correspondence is directed to both of them. However, in the specific business and subject files, the material is directed to that person with a major concern in the particular project.
