[3] He attended the American School of Classical Studies in Athens (ASCSA) in 1901, as a Driser Fellow of Columbia University.

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.

[citation needed] 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 (for whom Hill appears to have had unreciprocated romantic feelings).

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' (Professional Partnership).

[6] 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.
