The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Louis Mourier, a French civilian, for exceptionally meritorious and distinguished service in a position of great responsibility to the Government of the United States, during World War I. As Undersecretary of State of the Medical Service, Civilian Chief of the Medical Department of the French Army, Mr. Mourier placed all available resources of his great department, both in material and personnel, at the disposal of the American Expeditionary Forces. His advice was of great value, aiding us in the solution of many problems, and he rendered services of inestimable value in assisting us in securing proper evacuation and hospitalization for the sick and wounded.
