Ephraim Avigdor Speiser (January 24, 1902 – June 15, 1965) was a Polish-born American Assyriologist. He discovered the ancient site of Tepe Gawra in 1927 and supervised its excavation between 1931 and 1938. Speiser was married to Sue Gimbel Dannenbaum, granddaughter of Charles Gimbel of the Gimbel Brothers. They had two children together, Jean and Joel. Early life Speiser was born in Skalat, Galicia (then in Austrian Poland, now Ukraine) on January 24, 1902. He went to school in Lemberg (later called Lwow, now Lviv), attending the Imperial Gymnasium of Lemberg and later graduating from the College of Lemberg in 1918. Two years later, at the age of 18, he emigrated to the United States and eventually became a US citizen in 1926. In the United States, Speiser received his M.A. in Semitics at the University of Pennsylvania in 1923, studying under J.A. Montgomery and Max Margolis. He continued his studies under Max Margolis and earned his Ph.D. from Dropsie College in Philadelphia in 1924. Career From 1924 to 1926, Speiser was a Harrison Research Fellow in Semitics at the University of Pennsylvania. In 1926, he won a Guggenheim Fellowship to study the remains of the ancient Mitanni and Hurrians in northern Iraq. The members of the Mittani-Hurrian tribes still spoke Hittite; Speiser was one of few in the United States who could speak the language. In 1927, while in northern Iraq, Speiser discovered the Tepe Gawra (or “Great Mound”), one of the earliest known examples of civilization. During this time, he was Director of the Baghdad School of the American Schools of Oriental Research and taught at the Hebrew University in Jerusalem. From 1930-32 and 1936–37, Speiser served as Field Director of the Joint Excavation of the American Schools of Oriental Research and the University Museum, undertaking excavations in Tepe Gawra and Tell Billa, also known as Shibaniba. In 1936, Speiser also took over the position as field director for the excavation of the Sumerian site of Khafajeh after the University Museum took it over from the Oriental Institute in Chicago. In 1928 he was appointed assistant professor of Semitics at the University of Pennsylvania, and full professor in 1931. Only a few years later, he was appointed as Chairman of the Department of Oriental Studies, a position he used to develop the study of Assyriology at the University of Pennsylvania. During World War II, Speiser left academia to
