Educated at Cambridge, Harry Maude spent the years 1929-48 working as a civil servant and administrator in various Pacific Islands, in particular the British colony of the Gilbert and Ellice Islands. From 1948-57 he worked for the South Pacific Commission, following which he worked as a Research Fellow for the Australian National University Research School of Pacific Studies until 1971. He has published widely on aspects of Pacific Islands history and was a prime mover in the establishment of the Pacific Manuscripts Bureau.
