dilapidated he replaced it with a cottage in the town in 1957. Clark spent much of his leisure time visiting art galleries, and in later life he began collecting art, as well as Chinese porcelain, and Asian jade. Reception and legacy For Fagan, Clark was "one of the most important prehistorians of the twentieth century", an individual whose "intellectual influence on archaeology was enormous", producing a "legacy to prehistory [that] will endure for generations". The historian Adam Stout noted that Clark was "one of the century's most influential prehistorians". Coles similarly noted that he was "one of the founders of European and world-wide prehistoric studies, and there are many now who would assert his primacy in these fields over all other prehistorians of the 20th century". Coles noted that among continental European scholars, Clark was "the most respected British prehistorian" of his generation. Clark's work was however little known in the United States, where it was eclipsed in the 1960s by the growth of processual archaeology. A less grandiose assessment was left by the archaeologist Pamela Jane Smith, who stated that Clark made "major contributions to the establishment of prehistory as an academic subject at Cambridge University". The archaeologists Arkadiusz Marciniak and John Coles stated that Clark was one of the "eminent archaeologists" who helped to establish prehistoric archaeology as a "fully professional discipline" with explicitly outlined goals and methods and an institutional foundation. He was a pioneer in ecological, functionalist approaches to archaeology, as well as the first archaeologist to write a global prehistory of humankind. In November 1997, a Grahame Clark Memorial Conference was held at the British Academy in London. It was at the conference that John Coles invited Fagan to write Clark's biography. In 2007, an academic symposium was held to mark the centenary of Clark's birth at the Archaeology Museum of Biskupin in Poland; it was co-organised by the museum with the Polish Academy of Sciences and the Committee of Pre- and Proto-historical Sciences. On the basis of the conference, in 2010, Marciniak and Coles published a co-edited volume titled Grahame Clark and His Legacy''. They noted that up to that point there had been "little in-depth assessment" of Clark's influence in archaeology, in particular in contrast to the large number of Childe. Publications Clark, J.
