• The Yellow Fever Board, chaired by Dr. Walter Reed, with board members Dr. Jesse Lazear, Dr. James Carroll and Dr. Aristides Agramonte, began working on the task of ending the disease of yellow fever, which had killed hundreds of thousands in the Western Hemisphere. Dr. Lazear would die of the disease, but made the critical discovery that yellow fever could be ended by eradicating the mosquitos that spread it. In 1900, 1,000 people in Havana died from yellow fever; in 1901, only twenty did.
