The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Army Distinguished Service Medal (Posthumously) to Chief Nurse Lillian Aubert, United States Army Nurse Corps, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility. As Assistant Superintendent, Army Nurse Corps, in the office of the Surgeon General during World War I, Chief Nurse Aubert rendered services of the highest order. By her devotion to duty and great efficiency at a time when members of the Army Nurse Corps were being enrolled, equipped, and assigned to both overseas and home service she made an invaluable contribution to the work of the Medical Department in caring for the sick. She was taken ill while on duty on 2 October 1918 and died 6 October 1918, of pneumonia, in line of duty, as a result of overwork.
