Donald Proulx became fascinated by Nasca pottery forty-five years ago, when he was a student hired to catalog a collection of Peruvian artifacts. Over the years, although his research expanded to include site surveys and settlement pattern studies, he never lost his passion for Nasca ceramics. He has written extensively on all facets of Nasca culture, including Local Differences and Time Differences in Nasca Pottery, Nasca Gravelots in the Uhle Collection from the Ica Valley, and (with Helaine Silverman) The Nasca. He is professor of anthropology emeritus, University of Massachusetts at Amherst.
