Major '''Walter Reed''' (September 13, 1851 to November 23, 1902) was a physician in the [[U.S. Army]]. He is best known for his discovery that [[yellow fever]] is carried by the [[mosquito]], during a series of experiments in [[Cuba]]. As only humans will catch yellow fever, Walter Reed had to use human volunteers. Once it was known that mosquitoes carried yellow fever, it was possible to reduce deaths from yellow fever by mosquito eradication, allowing the completion of the Panama Canal.<ref>http://www.wramc.amedd.army.mil/visitors/visitcenter/history/pages/biography.aspx</ref>
