Academic recognition of RH Mathews. American researcher working at the South Australian Museum helps break the academic veto on RH Mathews’ work on Aboriginal language, culture and estates. This stand-off was established decades earlier by British trained ethnologists/scientists, especially Victorian Baldwin Spencer. Joseph Birdsell in conjunction with Adelaide scientist Norman Tindale publish a guide to Aboriginal territories and tribal identities. It includes Darkinung of the Hawkesbury-Hunter ranges, although Tindale’s interpretation of Mathew’s records of Darkinung grammar and the country in which it is spoken attracts critical scrutiny.
