John Rudder, PhD, has studied the Australian Aboriginal languages, of Arnhem Land (Gupapuyngu) in the Northern Territory and the state of New South Wales (Wiradjuri), Australia.
In 1964, Rudder went to Arnhem Land as a teacher, and later as a community development worker and educator among adult Indigenous Australians. In that time he learned to speak the language of the region, and analysed its grammar and syntax.
He sought to gain formal educational qualifications after moving to Canberra, and has since gained a master's degree in Anthropology focussing on Aboriginal Classificatory Theory and Cognitive Structures and a Doctor of Philosophy degree in Aboriginal Anthropology focusing on Yolngu Cosmology (focusing on beliefs regarding the nature of existence and how the world is ordered.)
From 1993 to 2010, Rudder was heavily involved, with Stan Grant, an elder of the Wiradjuri people, in reclaiming the Wiradjuri language that was at that time effectively dead, even though this is arguably the biggest tribe in New South Wales. He took anthropological studies and records amounting to the records of fewer than 2,000 words and applied the language and cognitive analysis he had previously applied to the Yolngu language, to begin to reconstruct the Wiradjuri language. With Grant, who provided a sense of the language remembered from his youth in World War II among Wiradjuri-speaking family and tribal members, notably his grandfather, they have established training sessions to teach the language across Wiradjuri country. Intensive weekend camps, workshops, and other sessions have seen a growing number of Wiradjuri speakers who are beginning to re-establish the language. For instance, these speakers are beginning to write songs and poems that are then being taught to children.
