The late Professor Marchant wrote widely in the fields of French, Chinese, and indigenous Australian history and culture, as well the geography and cartography of the Indian-Pacific region. He was created a Chevalier in the Ordre National du Mérite by the French president and had been a Fellow of the Royal Geographical Society. His last positions were Visiting Professor of History at Notre Dame University in Fremantle, Director of the Centre for the Study of the South Land, and Resident Scholar at the State Library of Western Australia. The first Volume of the Western Australian Exploration series was dedicated to Professor Marchant for his interest and assistance at the concept stage of the Project.
Doreen died in November 2011, during the preparation of Western Australian Exploration 1836-1845 for which she was a proofreader.

While living in Armadale she was member of the Community Heritage Advisory Committee for Armadale, Roleystone and Kelmscott. When Doreen and her husband retired to Augusta they became active and contributory members of the local community.
