Grace Simpson  Mary Grace Simpson (12 November 1920 – 8 February 2007) was a British archaeologist and museum curator specialising in the study of Roman ceramics, especially Samian ware. Simpson spent her early years in Newcastle, where her father F. G. Simpson was Director of Archaeological Field Research and went to school at Penrhos College. She served as a nurse during the Second World War. After the war, Simpson studied at UCL Institute of Archaeology, graduating with a Diploma in European Archaeology in 1948. Between 1950 and 1954 she was a research assistant to Eric Birley at Durham University. Between 1950 and 1972 Simpson was the Honorary Curator of the Clayton Collection of antiquities at Chesters Roman fort. She undertook postgraduate study at Lady Margaret Hall, Oxford and was awarded her DPhil from Oxford in 1960. The subject of this thesis was published in 1964 as "Britons and the Roman Army: A Study of Wales and the Southern Pennines in the 1st-3rd Centuries". She taught at Oxford for the Department of Extra-Mural Studies and was a visiting fellow at Haverford College, Pennsylvania. Simpson's study of the late Joseph Stanfield's investigations into samian ware resulted in the 1958 publication of "Central Gaulish Potters", which remains an essential work for the study of the subject more than fifty years on. She was one of the early member of the Rei cretariae Romanae fautores, a specialist study group for Roman ceramicists, following its founding 1957 and organised the 14th Congress of the society in Oxford and London in September 1984.
