He subsequently worked for the Southern Conference Educational Fund in North Carolina, served as director of the Chicago Commons Association (1969-1973) and as director of the Office of Human Development of the Catholic Diocese of Rochester, New York (1976-1978), and spent several years teaching college sociology at the Navajo Community College, Tsaile, Arizona, and at the University of North Dakota, Grand Forks. John R. Salter changed his name, circa 1995, to John Hunter Gray, his original family name, and in 2000 to just Hunter Gray. The collection contains correspondence; numerous speeches, reports, and other writings by Salter; partial files from some of his professional positions; his FBI files; newspaper clippings; and biographical and family history information. The photographic portion of the collection includes images of the Salter-Gray family; Hunter Gray, both alone and with others, as well as images related to Gray's civil rights activities in the 1960s and 1980s.
