Marcel Jungfleisch (1879 - 1958) was one of the leading numismatists in the twentieth century. He was from Cairo, Egypt and wrote extensively on Egyptian numismatics. He was a professor of Consernatorie of Arts et Metiers and a member of the Institute of Egypt. His extensive writings covered Islamic bronze weights from Egypt, Ayyubid glass jetons, Islamic Art Network, Roman Egyptian coins, Nubians in Egypt (1946), Nomes of Egypt (1946), and wrote for the Revue Numismatique in 1955. Sotheby's sold his collection in two vast sales in 1972.
