The criteria were announced in a War Department circular dated February 22, 1932, and authorized award to soldiers, upon their request, who had been awarded the Meritorious Service Citation Certificate, Army Wound Ribbon, or were authorized to wear Wound Chevrons subsequent to April 5, 1917, the day before the United States entered World War I. The first Purple Heart was awarded to MacArthur. During the early period of American involvement in World War II (December 8, 1941 – September 22, 1943), the Purple Heart was awarded both for wounds received in action against the enemy and for meritorious performance of duty. With the establishment of the Legion of Merit, by an Act of Congress, the practice of awarding the Purple Heart for meritorious service was discontinued. By Executive Order 9277, dated December 3, 1942, the decoration was applied to all services; the order required reasonable uniform application of the regulations for each of the Services. This executive order also authorized the award only for wounds received. For both military and civilian personnel during the World War II era, to meet eligibility for the Purple Heart, AR 600-45, dated September 22, 1943, and May 3, 1944, required identification of circumstances.
