The radiocarbon revolution may be seen in retrospect as the most decisive development in the archaeology of the 20th century. It is a pleasure, therefore, to have the opportunity of congratulating Radiocarbon on its jubilee celebration, and on the significant role that it has played in establishing a level of excellence in publication, against which the advances in that revolution could be measured. I well remember, as an undergraduate in Cambridge starting to read archaeology in 1960, how each new issue of Radiocarbon would be scrutinized for new dates bearing upon European prehistory. Glyn Daniel, then editor of Antiquity, would often begin a lecture with the announcement of some improbably early date for a Neolithic monument in Brittany or in Britain. It was clear that archaeology was being transformed, but not yet evident what the nature of the transformation would be.
