Professor William Frances ('Peter') Grimes (1905-1988), Director of the Institute of Archaeology in London, is often associated with Roman archaeology. Although his roots were in the classical world, he made a significant contribution to the study of pre-Roman Wales, and was in the vanguard of field ar­chaeologists in Britain considering prehistory (Gill in press; Hall and Macdonald 1988; Merrifield 1990; Miles 1989).
