The Army School of Nursing was a nursing school created by the United States government on May 25, 1918, during the height of World War I. The School was authorized by the Secretary of War as an alternative to utilizing nurses' aides in Army hospitals. Courses of instruction opened at several Army hospitals in July 1918.     Annie W. Goodrich became the first Dean of the Army School of Nursing. Although the Adjutant General authorized a military uniform and an insignia consisting of a bronze lamp superimposed on the caduceus, the students in the Army School of Nursing retained civilian status. In December 1918, there were 1,578 students in the program.
