First Woman Army Officer
Answer
On July 9, 1947, Florence Blanchfield became the first female officer in the United States Army.
After 30 years of service in the Army Nurse Corps, where she held the position of superintendent during World War II, Blanchfield earned her commission through the Army-Navy Nurse Act of 1947.
General Dwight D. Eisenhower appointed Blanchfield to be a lieutenant colonel in the Army, making her the first woman to hold permanent military rank in the United States. Blanchfield herself helped secure passage of the Army-Navy Nurse Act, which provided permanent commissioned officer status for members of the Army Nurse Corps.
