The Senior Seminar was officially established in 1958 as the Senior Officer Course. The original idea for a graduate-level training course on foreign affairs in the State Department originated in 1926, when
Loy Henderson proposed a sabbatical be established for senior officials in a memo to
Assistant Secretary Wilbur Carr. The Foreign Service Act of 1946 created the Foreign Service Institute and suggested senior training be made available through the Institute but no training at this level was instituted in the immediate aftermath of the Act. In 1955, Henderson was made Deputy
Undersecretary for Management and in late 1957, he asked Willard Barber to put together a course for senior leadership. Barber was the director of the political department at the
National War College and after the course's creation he was in charge of the first seminar. Students at the
Johns Hopkins University Paul H. Nitze School for Advanced International Studies submitted proposals for the curriculum for the seminar. In 2010, diplomat Allen L. Keiswetter was interviewed for the
Association of Diplomatic Studies and Training about the Senior Seminar of 1989–1990. Keiswetter said that during this year, the students were heavily involved in planning the Seminar. It was also the first year the Seminar took a trip to Alaska. == Purpose ==
