the management committee of the Institute of Archaeology, as well as the Prehistoric Society, of whose journal he remained editor. In 1951, he had been elected a Fellow of the British Academy, and in 1953 he gave the Academy's Reckitt Archaeological Lecture, which he devoted to a discussion of prehistoric economies. With his project at Star Carr completed, Clark returned his attention to the excavation of the Iron Age settlement at Micklemoor Hill. He oversaw two further seasons of excavation in 1952 and 1953, which was mostly overseen by Clare Fell, the assistant curator at the Museum of Archaeology. In 1954, Clark was made aware of Neolithic pottery and worked flints that had been discovered through an excavation at Hurst Fen near Mildenhall in Suffolk. Believing this to be likely evidence of a Neolithic settlement, he oversaw a project of excavation at the site in 1957 and 1958, although left most of the running of the excavation to Higgs. Clark was disappointed that he excavation revealed a number of scatters post-holes and pits but no structures. The site had nevertheless yielded important typological information about Neolithic pottery and provided greater knowledge about the Neolithic period in eastern England. It would prove to be Clark's final major excavation.Prehistoric Europe brought Clark wider visibility and resulted in his first opportunity to visit the United States. In 1952 he was asked to attend the inaugural meeting of the Wenner Gren Foundation for Anthropology in New York City. At the event Clark met the American archaeologist Gordon Willey, who became his good friend. In 1957, he returned to the U.S. to teach for a semester as the Grant McCurdy Lecturer at Harvard University. In 1958, Clark published his last piece of original research on the Mesolithic, an article on trapez-shaped microliths for the Proceedings. That year he also spent time in France's Dordogne region, visiting Lascaux cave and Hallam L. Movius's excavation of Abri Pataud. In 1959, Clark was elected President of the Prehistoric Society. In his presidential address he called for a less Eurocentric and more global focus on research into prehistory. To this end he produced a one-volume history of global prehistory, resulting in World Prehistory: An Outline, which was published by Cambridge University Press in 1961. Despite its title, over half of the book was devoted to the prehistory of Western and Central Europe, reflecting how little was known about much
