He became a professor at the University of Pennsylvania in 1994 and served as the department chair of landscape architecture and regional planning until June 2000, now being emeritus.
In his youth he walked extensively in the mountains of the English Lake District and in Switzerland, and spent time with his maternal grandfather, Frank Dixon, a school headmaster and entomologist.
He began his career with teaching positions in English literature with emphasis on its relationships with the visual arts at the University of Michigan, Vassar College, Exeter, York, Leiden, East Anglia, Bedford College, London and then Dumbarton Oaks where he was the Director of Studies in Landscape Architecture.
His route to the study of landscapes began with his research into the 18th-century of Alexander Pope and a trip to Stowe, where he toured the grounds for several days with the history master of the boys' school there.
John Dixon Hunt is a member of the Graduate Groups in PhD architecture, historic preservation, history of art, comparative literature and Center for Italian Studies Committee.
