He attended the American School of Classical Studies in Athens in 1901, as a Driser Fellow of Columbia University. He continued at the school as a Fellow of the Archeological Institute of America for two years. He moved back to the United States, where he was Assistant Curator of Classical Antiquities at the Museum of Fine Arts and Lecturer in Greek Sculpture at Wellesley College. He then returned to ASCSA and served as director of the school for the next twenty years, from 1906 to 1926. As director, he supervised the Corinth Excavations where his focus was the springs of Peirene, Glauke and the Sacred Spring. He also participated in the study of the monuments of the Athenian Akropolis, specifically the Erechtheum and the Parthenon. Hill was director of the University of Pennsylvania's Archeological Expedition in Cyprus at the excavations of Lapithos and Kourion in 1932 and from 1934 to 1952. He was the Charles Eliot Norton Lecturer of the Archeological Institute of America for 1936–1937. He had a scholarly interest in architecture, sculpture, and topography, and was involved in research of epigraphy.
Private life
Hill married archeologist Ida Carleton Thallon in 1924, and the two moved in together in Athens with Thallon's long-term partner Elizabeth Pierce Blegen and her new husband Carl Blegen. They referred to this arrangement - by which Thallon Hill and Pierce Blegen were able to continue their previous relationship, having specified that they would still travel together and spend time alone as well as with their husbands - as 'the family', 'the quartet', or 'the Pro Par'. In 1929, the family moved into a new house at 9 Ploutarchou Street, and their home became a popular meeting place for archeologists, students of all foreign schools, diplomats, Vassar alumnae, Greek scholars, Fulbright scholars, and the staff of the American embassy. During World War II, Hill remained in Athens to look after the home on Ploutarchou Street while Ida Hill moved to the United States with the Blegens for the duration of the war. He volunteered with the Red Cross in Greece during World Wars I and II and served on the Greek Refugee Settlement Commission in the 1920s. Ida Hill died at sea on a return voyage to Athens in 1954, with Elizabeth Blegen at her side. Hill died in 1958 in Athens. Elizabeth Blegen died in 1966. Carl Blegen died in 1971. The four archeologists and friends are buried next to each other in the First Cemetery of Athens.
