Mary Harfield (28 February 1879 - 1970) was a self-taught, Australian-British archaeologist, whose understanding of Cadbury Castle through field survey influenced the work and interpretations of the site by others, including Ralegh Radford.
In 1910 she returned to England to study nursing at St Bartholomew's Hospital in London.
[1] In later life she moved to Somerset and became interested in the archaeological remains local to her, particularly Cadbury Castle.
[1] During the 1950s Harfield's field-walking identified a range of ceramics, including Neolithic pottery and an early medieval sherd.
[2][3][4][5] Her work was used by Ralegh Radford to argue that there was significant Neolithic occupation at the site.
