Duncan is an editor based in the Military History Section. After completing a doctorate in English literature, Duncan began a career in publishing, first helping establish Pandanus Books, and then ANU E Press. In the process he was involved in such diverse activities as editing, production, design, distribution, copyright and contract management, and published more books, journals, magazines, catalogues, festschrifts, atlases, and ebooks than he cares to remember. Following a seemingly unending series of existential and mid-life crises – and the birth of two children – he departed academia to work as a freelance editor and publisher while engaging in primary kidwrangling. He joined the Military History Section of the Australian War Memorial in 2016.
