WALTER REED (1851-1902) was born in Gloucester County, Virginia and received his M.D. degree from the University of Virginia in 1869. He entered the Medical Corp of the U.S. Army in 1875. During the Spanish-American War he was made chief of the commission to study the origin and spread of typhoid fever in army camps, which concluded that the flies were the most important carriers of disease. In 1900 he was appointed chief of the Yellow Fever Commission, and with Dr. James Carroll, Dr. Jesse W. Lazear and Dr. Aristide Agramonte, proved that yellow fever was transmitted by the bite of the stegomyia mosquito.
