The Army Medical School (AMS) was founded by U.S. Army Brigadier General George Miller Sternberg. According to some, it was the world's first school of public health and preventive medicine. (The other institution vying for this distinction is the Johns Hopkins School of Public Health (1916).) The AMS ultimately became the Army Medical Center (1923), then the Walter Reed Army Institute of Research (1953).[citation needed]
