British Egyptologist noted for his careful surveying and study of prospective sites. He discovered galleries of the Bucheum in Armant, burials of Nubian X-Group kings, queens and nobility of 4th-6th century AD, and at Saqqara, excavating many Archaic Period mastabas. His most important discovery was a row of 1st-Dynasty tombs attributable to kings or nobles. He excavated at Thebes-West Bank, Nubia's Buhen and Ballana and Qustul.
