An exhibit at the Georgia Southern University Museum sounds out the horrific events of 100 years ago, revealing a war that not only left more human beings dead than any before it but brought changes in civilization that echo today. “The Great War that Changed the World, 1914–1918” also exhibits the enthusiasm of a young historian turned curator, the talents of graphic design students and artifacts lent by local people. The First World War often has been overshadowed by the Second and by the American Civil War in local historical interest, said Sheila Boone, the project’s coordinator and graduate-student curator.
