Dorothy Annie Elizabeth GarrodDied 18 Dec 1968 at age 76 (born 5 May 1892).English archaeologist who, between the wars, dominated a string of pioneering excavations in the Near East (1929-34), most notably the 22 month excavation at Mount Carmel, Palestine, which put Near Eastern prehistory on the map. The Mount Carmel cave deposits spanned 200,000 years of human occupation, and finds included over 92,000 stone tools. Most important were the finds of human fossils, including the skeleton of a female Neanderthal dated c. 110,000 BC, the first ever to be found outside Europe. This led on to the discovery of more skeletal remains of primary importance to the study of human evolution. A leading authority on the Paleolithic for many years, Garrod was the first woman to receive a professorship at the University of Cambridge (1939-52). |
