Lee Chadwick (born April 1930) American anthropologist and archeologist, primarily known for his contributions to the Handbook of Middle American Indians. Robert Chadwick obtained his Ph.D. in anthropology from Tulane University in 1974. His dissertation, directed by Professor Robert Wauchope, was titled The Archaeology of a New World "Merchant" Culture. His notable collection of works during his years of excavating and reconstruction at Teotihuacan and other sites contains articles, publications, analysis of the artifacts discovered, sketches, illustrations, photographs on pre-Columbian culture, and a significant catalog prepared by Chadwick of the stone, ceramic and semi-precious artifacts found in north-eastern Costa Rica. Chadwick gave a number of his papers to Dr. Donald Robertson, of Tulane University. They were subsequently saved by his wife Martha Robertson, who recognized their value. She then turned most of them over to the Latin American Library; and the rest of the papers arrived following her death. Today Mr. Chadwick is now retired and lives in New York City.
