"Walter Reed's Clinic," the location of the present day health clinic at Washington, D.C., occupies what was from 1898 until 1909 the General Hospital at what was then Washington Barracks, long before the post was renamed in honor of Lt. Gen. McNair who was killed in 1944. The hospital served as the forerunner of Walter Reed General Hospital; however, the Victorian era waterfront dispensary remains and is perhaps one of America's most historically significant military medical treatment facilities. It is reported that Walter Reed lived and worked in the facility when he was assigned as Camp Surgeon from 1881 to 1882. After having served on other assignments, he returned as Professor of Medicine and Curator of the Army Medical Museum. Some of his epidemiological work included studies at Washington Barracks, and he is best known for discovering the transmission of yellow fever. In 1902, Major Reed underwent emergency surgery here for appendicitis and died of complications in this U.S. Army Medical Treatment Facility (MTF), within the very walls of what became his final military duty assignment.
