On the centenary of the signing of the Lausanne Convention, the American School of Classical Studies at Athens presented an exhibition highlighting a monumental humanitarian undertaking etched in the memory of history: the American relief aid offered to Greece from 1918 to 1929. The exhibition brought to light the tireless efforts of diverse individuals, ranging from political appointees and philanthropic leaders to educators and dedicated relief workers. Motivated by a sense of duty rooted in their Christian, patriotic or personal beliefs, they collectively played a pivotal role in reshaping Greece after 1922. The exhibition drew on a rich array of sources, including correspondence, official documents, rare publications, photographs, artifacts, posters, and short films. These treasures, which come from the important collections of the American School of Classics in Athens, but also from various institutions, are presented here for the first time, weaving a fascinating narrative with special significance.
