In 1900, Major Walter Reed, Chief Surgeon of the U.S. Army, led a team to Cuba to investigate yellow fever, the disease that had killed an estimated 100,000 people in the US in the 19th century alone. Reed and his team tested the theories of a doctor named Carlos Finlay who believed that mosquitoes spread the disease.
