Frank Woolnough was succeeded by Guy Maynard (1877–1966), previously of Saffron Walden Museum, who was curator from 1920 to 1953. Maynard was Secretary and Editor of the Prehistoric Society from 1921–1936, when this role was taken over by the Cambridge archaeologist Charles Phillips. Maynard and Reid Moir made a team interested in archaeology and developed this work strongly on behalf of the museum, excavating in various parts of Suffolk. Museum assistants Harold Spencer and Francis Simpson became specialised in geology and natural history from the 1920s, evolving a departmental structure for the museum through their work and publications with the Suffolk Naturalists' Society and the Ipswich and District Natural History Society. Reports of archaeological work went to the Suffolk Institute of Archaeology Proceedings, of which both Reid Moir and Maynard were officers.
