The President of the United States of America takes pleasure in presenting the Navy Distinguished Service Medal to Admiral William Daniel Leahy, United States Navy, for exceptionally meritorious and distinguished service in a position of great responsibility to the Government of the United States. As Chief of Naval Operations from January 1937 to August 1939, he was charged with the responsibility for the planning and administration of the U.S. Navy during a period when the greatest peace time expansion in its history was reaching its peak. The continuous and uninterrupted reliance placed upon his advice and counsel by the Secretary of the Navy, by the Congress and by the President was demonstrated by measures both executive and legislative, the value of which are clearly evidenced in the present high state of readiness and efficiency of the United States Fleet and of the entire Naval Establishment. The extraordinary qualities of leadership and administrative ability that have marked his tenure as the highest ranking officer in the Navy have been exemplified throughout his entire Naval career.
