After preliminary training at the Liverpool Institute of Archaeology, he went to Egypt for the first time as an assistant on the staff of the Egypt Exploration Society expedition in 1923. There he aided in the excavation of Amarna. By 1924, he was already field director of Sir Robert Mond's excavations at Thebes for the University of Liverpool. He made several clearings, restorations and protective operations into a score of tombs at Sheikh Abd el-Gurnah. Between 1924 and 1928, continuing as Director of the Mond Expedition, he worked on excavations at Nubia, Luxor and Thebes. In 1929 he was appointed field director of the Archaeological Survey of Nubia under the auspices of the Egyptian Government Service of Antiquities, with authority to explore and excavate all ancient sites in Nubia which were soon to be flooded after the erection of the Aswan Low Dam. Working at Quban, Ballana and Qustul, he excavated the X-Group of tombs dating to the 3rd to 6th century A.D. He was assisted in his work by his wife, Molly. The completion of the excavations of the fortress at Buhen ended his work in Nubia. He then became director of fieldwork at Luxor and Armant. During the years 1935 to 1939 he was the director of the Archaeological Survey of Nubia. During these years as director, Emery also investigated several early dynastic tombs at Saqqara. While at Saqqara he made the significant discovery of a "zoo" of mummified animal remains. In 1937, Emery also discovered a disc-shaped object referred to as the Schist Disc while excavating the burial chamber of the Tomb of Prince Sabu, son of Adjuib Pharaoh, governor of the I Dynasty. The object has been on display to the public on the first floor of the Egyptian Museum in Cairo, labelled as Vase of schist. Following the years of interruption by the war and his service as a diplomat, Emery worked in the Sudan. In 1964, he returned once more to Saqqara where he discovered the "enclosure of the sacred animals". Emery obtained the Chair of Egyptology at University College London in 1951, and was a professor of Egyptology in London from 1951 to 1970. He was elected to the British Academy Fellowship in 1959. His principal publications are Great tombs of the 1st dynasty, 1949-58; Archaic Egypt, 1961; and Egypt in Nubia, 1965. Emery died in March 1971.
