Early life Born
Sonia Elizabeth Chadwick, on 5 November 1933 in
Crayford, she was the only child of Albert Andrew Chadwick and Doris Chadwick (formerly Doris Benger). The
Oxford Dictionary of National Biography notes that Albert Andrew Chadwick was an engineer, but gives no information on Doris Chadwick beyond her name. Sonia Chadwick excavated at
Lullingstone Roman Villa (Kent) as a school girl, and at an early medieval site at
Morgan Porth (Cornwall) from 1951 to 1953. The experience at Morgan Porth shaped her later interest in early medieval archaeology. She studied English at
Bedford College, University of London, before undertaking postgraduate research supervised by
Vera I. Evison.
Career In 1956, Chadwick began a multi-year excavation at a prehistoric site on
Longbridge Deverill Cow Down in Wiltshire. The work was carried out for the
Ministry of Works and concluded in 1960. Chadwick contributed to the inaugural volume of
Medieval Archaeology in 1957, published by the recently established
Society for Medieval Archaeology, editing a posthumous article on the early medieval art of the
Jutes from
Anglo-Saxonist Edward Thurlow Leeds. Chadwick's early research explored the decorated metalwork found in early medieval graves. She produced a study reassessing 1920s finds from the Anglo-Saxon cemetery at Finglesham, a prelude to her own excavations there from 1959. The field of Anglo-Saxon archaeology developed significantly in the early 20th century with systematic approaches to data; Hawkes was part of a wave of archaeologists including
J. N. L. Myres, Vera I. Evison, and
Audrey Meaney who continued this trend, investigating cemeteries to explore the history of England in the early Middle Ages. (later renamed the North Lincolnshire Museum) from 1958 to 1959 as a curator.|alt=A two-storey red-brick building with annexes on the right. In 1958, she was appointed curator of
Scunthorpe Museum. The museum took over excavations at an Anglian cemetery in
Fonaby, Lincolnshire; Chadwick was responsible for the finds and began indexing them – a project which was built on by Alison M. Cook and the finished product published more than two decades later. Chadwick spoke about the work at Longbridge Deverill at the "Problems relating to the Iron Age in Southern Britain" conference in December that year, organised by the
Council for British Archaeology at the
Institute of Archaeology in Oxford. Chadwick met fellow archaeologist
Christopher Hawkes at the conference and they married in January 1959. She left Scunthorpe Museum in 1959 to join the Institute of Archaeology at the
University of Oxford, where Christopher lectured, as a research assistant. She remained with the institute, later becoming a
lecturer, until she retired in 1994. Christopher joined Sonia at Longbridge Deverill for the final season of excavation in 1960, which
Paul Ashbee described as a "honeymoon joint enterprise". . The buckle is on display in the
Ashmolean Museum. From 1959 to 1967, Hawkes led excavations at
Finglesham Anglo-Saxon cemetery in Kent. Hawkes was elected a
Fellow of the Society of Antiquaries (FSA) in 1961. Between 1961 and 1962, she also led excavations at an Anglo-Saxon cemetery at
Worthy Park in Hampshire. From 1963 to 1971, Hawkes catalogued a collection of finds from the 18th-century antiquarian
Bryan Faussett. Hawkes' research focus was on Anglo Saxon cemeteries in Kent. A major piece of work on Late Roman zoomorphic belt fittings, "Soldiers and settlers", prompted much debate. Written in collaboration with
Gerald Dunning, the paper was also translated into German. In the 1960s, Hawkes began a reassessment of material excavated at the early medieval cemeteries at
Sarre and
Bifrons in the 19th century. The results were not published in her lifetime. In 1973, Hawkes was appointed lecturer in European archaeology at the University of Oxford.
Updown early medieval cemetery in Kent was discovered that year, about a mile from the Finglesham cemetery. Hawkes became interested in the site due to its proximity to Finglesham where she had already worked; she worked with the owners and they commissioned her to conduct a
rescue excavation in 1976 ahead of the East Kent Water Board's plans to run a pipeline through the site. The work uncovered 36 graves, but further excavation was curtailed after one of the landowners died, and Hawkes spent time publishing the results of the excavation. The 1970s saw an increasing number of studies in the field of Anglo-Saxon archaeology; in the context of creating new venues for publication of detailed studies, Hawkes supported the foundation of the
British Archaeological Reports book series. She had an advisory editorial role and the first book in the series was written by one of Hawkes' research students,
Tania Dickinson. In 1979, she co-founded the publication series
Anglo-Saxon Studies in Archaeology and History with
James Campbell and David Brown, and organised a series of interdisciplinary seminars and conferences in
Anglo Saxon studies. The first two volumes of
Anglo-Saxon Studies in Archaeology and History were published in the British Archaeological Reports book series. Sonia collaborated with her husband, Christopher Hawkes, as a researcher and they co-edited
Greeks, Celts and Romans and Christopher contributed a section to Sonia's article on the Finglesham Man. They translated into English and printed
Joachim Werner's 1982 article on the excavation and publication of the
Sutton Hoo ship burial. Christopher's health began declining in the 1980s, and around this time Sonia and he spent time travelling in Europe. As Christopher's health worsened, Sonia spent more time caring for him and less time on research. After his death in 1992, Sonia "was tireless in ... ordering his books and papers". Hawkes took early retirement in 1994. She married Svetislav Petkovic in May 1995, a retired
factory inspector. Sonia Petkovic died in Oxford on 30 May 1999, having been diagnosed with
cancer. ==Reception and legacy==
