Prof. Clark was instrumental for increasing the size and scientific value of the Old World prehistoric collections at the PAHMA with assemblages from his research in Africa and Asia and by promoting active programs of exchange with museums in Africa and Europe intended to complement the preexisting collections.
The museum houses assemblages from a few archaeological sites excavated by his students mainly in the early 1970's. Some of these collections were never fully studied and published by their original investigators. This quartzite core is part of a sizable assemblage from an excavation in the Democratic Republic of the Congo between 1971 and 1973. The stone tools were deposited at the museum a few years later with little information as to their provenience, collection methods or field notes. J. Desmond Clark recalls this project in his memoirs*:
Various sites in the Congo or Rwanda have a longish sequence from the late Acheulean through the Middle Stone Age. One site in the Katanga Province, in Zaire, it was dug by a delightful old French priest, Pere Anciaux de Faveaux, who had found this site and reported on it in the Third Pan-African Congress [...]. He found a very nice Acheulean site at the Pupa River near Katentania on the Biano River, and a student of mine, Carney Schokkenbroek [...] did a very nice excavation of the Acheulean and overlying Lupenbaum following on from what Anciaux did, and she was out there for probably two years, I think, working on those collections, doing the excavation, et cetera, with Anciaux. But she never wrote it up. We were hoping she would write it up, but she seems to have disappeared now.
Perhaps she had disappeared but the stone tools are still in Berkeley.
