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 Colonel (Medical Corps) George Walker, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I. As a member of Base Hospital No. 18, in the prevention of the spreading of diseases at the base ports, and later as Clinical Chief of Genito-urinary Section of the Medical Department in France, Colonel Walker rendered services of inestimable value to the Government. His untiring energy and unremitting devotion to duty, coupled with his technical knowledge as a professional urologist, were of material value and contributed markedly to the successful operations of the American forces in France.
