He received a BA from Dartmouth College in 1933, an MA from Harvard University in 1935, and a diploma from the Graduate Institute of International Studies in Geneva in 1936.
In 1949, Hart opened the U.S. consulate in Dhahran, the site of Saudi Arabia's newly discovered oilfields.
He was replaced when Richard Nixon took power and National Security Advisor Henry Kissinger moved U.S. foreign policy in the region in a more pro-Israel direction.
Additional material about Parker T. Hart can be found in the University of Wyoming American Heritage Center's archives.
The archives include correspondences, reports, speeches, and subject files about development of business possibilities in, and the political climate of, the Middle East for his consulting work with the Bechtel Corporation, as well as RCA, U.S. Steel, and IBM.
