Stephen Galatti (August 6, 1888 — July 13, 1964) was for many years the Director General of the AFS, American Field Service.
He first joined the American Field Service in 1915 and served as second in command to the founder and first director of AFS, A. Piatt Andrew.
Despite American isolationism, Galatti organized and equipped the first unit of the AFS, and subsequently served through the war as a Director-General with the rank of Colonel.
Searching for a role for the AFS following the war, he founded the Scholarship Program (AFSIS) in 1946, and then led the AFS as its president for the rest of his life, over time transforming it from an auxiliary medical corps for wartime into an international educational exchange service with tens of thousands of volunteers worldwide.
During his lifetime, Stephen Galatti received the Croix de Guerre and the post of Chevalier of the Legion of Honor, Commander of the Order of the British Empire, the Medal of Freedom, the posts of Officer of the Order of Orange-Nassau and Verdienstkreuz erster Klasse (Bundesrepublik Deutschland), and honorary MA from Yale, and honorary LL.D.
