The  [Linguistics] Program also sponsored the development of a series of Navajo language courses, which were formally established in the Department of Modern and Classical Languages in 1970. Closely associated with the teaching of Navajo was the beginning of Spolsky’s Navajo Reading Study project in 1970 which supported a number of graduate students in linguistics and brought the Navajo linguists William Morgan and Robert W. Young to campus as adjunct professors and researchers. (Bills MS, 1989)
