This folder includes the correspondence of Louis J. Frank with Beth Israel Hospital medical staff serving in World War I. Correspondence is mainly sent from "somewhere in France," but also from Germany and Fort Benjamin, Indiana in the U.S.
Topics include discussion on daily life for those serving in the war, Russia's role in the war, the status of the new Beth Israel hospital building (future Dazian Pavilion), medical staff shortages at Beth Israel and in the United States, the Influenza Epidemic of 1918, discussions of wartime surgery, discussions of x-ray training for military doctors, the status of various Beth Israel doctors at home and abroad, and global and local politics, particularly related to Congressman Isaac Siegel. Two postcards were also sent from Leo B. Meyer from Chartreuse de Vauclaire, a monastery turned military hospital in France. Letters also make various references to the Mount Sinai Hospital unit.
