Ida Carleton Thallon was born in Brooklyn, New York. She attended Packer Collegiate Institute and went to Vassar College, where she received her BA degree in 1897 and her MA in 1901. From 1899 to 1901, she studied at the American School of Classical Studies at Athens, and was one of the first women there permitted to participate in an archeological dig, joining her friend Lida Shaw King in Charles
Weller’s excavations at the Vari cave, sacred to Pan and the Nymphs, in Attica. Back in the USA, she received a PhD from Columbia University in 1905. She taught at Vassar for many years on three different subjects: Greek, Latin, and History. In 1914, she published her first book, Readings in Greek History, which received excellent reviews. In 1924, she married Bert Hodge Hill, an archeologist who was Director of the American School, moved to Athens permanently, and devoted herself to archeology. Subsequent books included Rome of the Kings (1925), and Decorated Architectural Terracottas in the Corinth Series of the American School (IV, I, 1929) with Lida Shaw King. She published The Ancient City of Athens (1953) shortly before her death and left behind a nearly-completed manuscript of another book on ancient Greek sites outside Athens.
