Obituary

Professor Edward Hall

Professor Edward (Teddy) Hall, who died on11 August 2001, was one of the pioneers inthe establishment of the practice of archaeom-etry—the application of the physical sciences toproblems of archaeology. The name Archaeome-try also became identified with the house journalof the Oxford University Research Laboratoryfor Archaeology and the History of Art foundedby Professor Hall in collaboration with ProfessorMartin Aitken.

All aspects of physics applied to archaeologyfell within Hall’s orbit of interests. Educated atEton and New College, Oxford, he specializedin science and took a PhD in X-ray fluorescencespectroscopy, an aspect of analysis that provedfruitful to him over many years in the study of awide range of artefacts. Early in his scientificcareer he contributed to the proof that thePiltdown skull was a forgery. Much later, in 1988,following his campaign for an accelerator 14Cdating laboratory at Oxford, he joined perhaps themost famous dating controversy, that of the Turinshroud. Hall produced a date no earlier than themid-thirteenth century AD for linen specimensfrom the shroud, thus adding to the mystery ofits origin.

Although Teddy Hall’s role in the activitiesof the dating Laboratory became less prominentover the years, he remained a linchpin in itsprogress and, through his manufacturing com-pany, Littlemore Scientific Engineering, made‘firsts’ of a range of analytical and, significantly,geophysical equipment. It is in this second cat-egory of advance that his name will live on inarchaeological prospection.

unrecognized. He was a trustee of the BritishMuseum and the Science Museum and advisorto the Science Research Council and EnglishHeritage. He became a Fellow of the BritishAcademy in 1984 and appointed a CBE in1988. There is now an Edward Hall Chair in

Archaeological Science at Oxford. This cheerful,generous, but extremely shrewd man of highscientific prowess will long be remembered by allwho had the privilege of knowing him.
