Dr. Carlos J. Findlay, president of the Board of Health, Havana, Cuba. Dr. Findlay early announced the carriage of yellow fever by a certain species of mosquito (the same one, in fact, which was definitely proved to be the carrier), but his experiments were not conclusive, and his conclusions were not accepted by the scientific and medical world until nearly twenty years later, when the U. S. Army Commission (Reed, Carroll, Lazear and Agramonte) brought about the overwhelming proof which was generally satisfactory. Findlay's announcement, however, was based on many years' study of the disease and of the mosquito vector.
