The Elizabeth Hudson Papers consist of four albums of photographs and autographs which document Elizabeth Hudson's service as a nurse in Paris during World War I. The photographs depict French and Moroccan wounded soldiers being treated at the American Ambulance Hospital in 1916 and 1917. The American Army and Red Cross took over the hospital in 1917 after which it was known as American Military Hospital No. 1. Photographs after 1917 also portray American wounded. The albums contain identifications of patients giving names, hometowns, and place, date and extent of injuries. There are also patients' autographs, expressions of gratitude, occasional letters, and Hudson's later annotations scattered through the volumes. Several photographs, especially in the album in folder 3, picture battlefields and the destruction of towns. The album in folder 4 contains photographs of the hospital staff and of the victory parade in Paris in 1919.
The Elizabeth Hudson Papers were transferred to the Manuscripts and Archives Department from the Beinecke Rare Book and Manuscript Library in 1987.
