Walter Reed (1851-1902) was a United States Army doctor who became internationally known after he and his colleagues on the Surgeon General's Yellow Fever commission discovered that the mosquito was the vector for the transmission Yellow Fever. This lead to the virtual eradication of the disease, saving countless lives. In 1902, Reed's life was cut short by complications from appendicitis. His friend and colleague, William Cline Borden, operated on Reed, but was unsuccessful in saving his life. Borden wanted Reed's legacy to continue, and envisioned the creation of an Army medical center that encompassed medical care, research, and education. He wanted the hospital to be named after his dear friend, Major Walter Reed. He repeatedly petitioned Congress, and in 1905, the Army was granted the funds to begin construction on Walter Reed U.S. Army General Hospital.
