For those who are familiar with Fort McNair in Washington, DC this is where Reed conducted his research. From wiki:
“A general hospital, the predecessor to the Walter Reed Army Medical Center, was located at the post from 1898 until 1909. Major Walter Reed found the area's marshlands an excellent site for his research on malaria. Reed's work contributed to the discovery of the cause of yellow fever. Reed died of peritonitis after an appendectomy at the post in 1902. The post dispensary and the visiting officers' quarters now occupy the buildings where Reed worked and died.”
