one of the great interpreters of Mesopotamian culture. Born in Denmark, Jacobsen studied Assyriology first at the university of his native Copenhagen and then, in the late 1920s, at the University of Chicago. Throughout his life, he was passionately and deeply committed to the study of ancient Mesopotamia, its land, cultures, and languages.
Jacobsen was a field assyriologist with the Iraq Expedition of the Oriental Institute (1929–1937), working closely with Henri Frankfort, its director, as well as with Pinhas Delougaz, Seton Lloyd, and Gordon Loud. He was the epigrapher at Khorsabad and in the Diyala region and led the excavation at Ishchali. Together with Lloyd, Jacobsen excavated Sennacherib's aqueduct at Jerwan. He was instrumental in introducing to Iraq the method of systematic surface ceramic survey.
Returning to Chicago in 1937, Jacobsen began a twenty-five-year affiliation with the university. From 1946 to 1951, he was director of the Oriental Institute and then dean of the Division of Humanities. As director, he gave new shape to the Assyriology faculty of the Oriental Institute and to American Assyriology, in general. Moreover, he set the agenda for American archaeology in Iraq by reestablishing American excavations at Nippur jointly with the University of Pennsylvania and setting in motion the surface surveys that would lead to his and Robert McC. Adams's important discoveries regarding waterways, salinization, and settlement patterns (Jacobsen and Adams, 1958). Disagreements over the policies, direction, and execution of the Chicago Assyrian Dictionary led to Jacobsen leaving Chicago in 1962 for Harvard University, where he taught until his retirement in 1974.
Jacobsen's unique blend of textual scholarship, knowledge of art and archaeology, quest for conceptual patterns, appreciation of the environment and way of life of ancient Mesopotamia, and his own deep human sympathy allowed him to fathom the meaning and recreate the image of a past civilization. He approached the task in an existential spirit and saw that alien and distant human life was something that not only existed in its own terms, but also mattered very deeply for the enduring human spirit.
