Charles Stuart KennedyOral History Director – Charles Stuart Kennedy has been director of the Foreign Affairs Oral History Program since its inception in 1985. A career officer in the US Foreign Service from 1955 to 1985, he retired with the rank of Minister Counselor. Mr. Kennedy was consul general in Naples, Italy (1979-81), Seoul, South Korea (1976-79), Athens, Greece (1970-74) and Saigon, South Vietnam (1969-70). He also served in Washington D.C., Germany, Saudi Arabia and Yugoslavia. He was educated at Williams College (BA) and Boston University (MA), and served four years (1950-54) in the United States Air Force, including duty in South Korea, Japan and West Germany.

He was awarded the Foreign Service Cup from the Director General of the Foreign Service in 1997 for his work as an oral historian.In June 2014 the American Foreign Service Association (AFSA) gave him the Award for Lifetime Contributions to American Diplomacy in recognition of his distinguished Foreign Service career and a lifetime of public service. Previous recipients of this prestigious award include U. Alexis Johnson, Frank Carlucci, George H.W. Bush, Lawrence Eagleburger, Cyrus Vance, Lee Hamilton, Thomas Pickering, George Shultz, Richard Lugar, Sam Nunn, Bruce Laingen, and George Landau.

Early in his Foreign Service career, Stu realized that there was no real record of the lives and contributions of the men and women who have served in the United States Foreign Service. As a result, many Americans have no idea of these individuals’ many contributions and sacrifices, and suffer from serious misconceptions about what Foreign Service members do. In 1986, after retiring from the Foreign Service, Mr. Kennedy became managing director of The George Washington University’s Foreign Service History Center. There he created the Foreign Affairs Oral History Collection and began recording the insights and experiences of American diplomats. The program moved to Georgetown University and then, in 1988, to ADST. In that capacity, he has personally interviewed more than 1,000 retired American diplomats, some of whose careers date back to the 1920s.

At the Department of State he held the positions of Deputy Director of UN Political Affairs, Associate Spokesman, Director of Central African Affairs, and Deputy Assistant Secretary of State for Africa, among others.After leaving the Foreign Service, Ambassador Brown was Director of the Dean Rusk Program in International Studies at Davidson College from 1995 to 2001. He has a BA in International Relations from Pomona College, an MA in International Relations from Yale University, an MA in Political Science from NYU, and a Ph.D. in Political Sociology from Cape Coast University in Ghana.
