Established in 1919 as a direct response to the United States’ involvement in the First World War, the Walsh School of Foreign Service (SFS) at Georgetown University has long excelled in its mission to train students for international service. Since its inception, SFS has provided a rigorous education grounded in theory, practice, and the Jesuit value of service to numerous alumni who have shaped global affairs in pathbreaking ways. SFS 100: A Century of Service is a handsomely illustrated volume that celebrates the school’s first one hundred years and the faculty and alumni who have made SFS the world’s top school of international affairs. And this collection of stories reflects the people and ideas that have shaped SFS’s identity and impact. Organized thematically to link the development of the school to world events over the last century, SFS 100 profiles key alumni and faculty who have applied their knowledge to the greater world in their varying positions as heads of state, diplomats, military leaders, business executives, aid workers, media figures, professors, and more. In recording these experiences, the book also traces SFS’s impact on the role of women in international affairs, highlighting women who have pushed boundaries for the betterment of the United States and the world. In describing the work of diverse SFS alumni, this book charts the evolution of the school as it upholds and adapts its practices in a continuously changing world. Madeleine Albright, Mortara Endowed Distinguished Professor in the Practice of Diplomacy, sums up the driving ethos of SFS best: “As long as there are wrongs in this world, there must also be those trained, and trained at the highest level, to right them.” SFS 100 celebrates the remarkable individuals who have upheld this mission for a century and promise to extend it well into the next.
