The Vernon A. Walters Collection In 2002 the National Intelligence University was honored to accept a gift from the estate of the late Ambassador Vernon A. Walters, U.S. Army. This gift included his photographs, documents, personal and professional correspondence, awards and memorabilia documenting a half-century career that was both distinguished and extraordinary. In 2005 the College also acquired his professional diaries. The addition of the diaries gives the College not only the distinction of being the repository for materials on the life of Ambassador Walters but also a unique documentary record and resource for historical research.The Vernon A. Walters room, located in the National Intelligence University , showcases many of these historic documents and artifacts including presidential letters, photographs, and memorabilia.
