Dr. Walter Reed, U. S. A., president of the U. S. Army Yellow Fever Commission, he who is to he given the principal credit for the scientific demonstration of the transmission of yellow fever by a mosquito. Dr. Reed died shortly after the complete demonstration was announced, his death being attributable in part to the strenuous work which he had done in connection with these investigations. He was always very loath to have his picture published, and for a long time the only one known was that taken in his early manhood, and which the writer used in an article in the Century Magazine of October, 1903. The present picture is evidently from a photograph taken not long before his death, and has been given to the writer by the Army Medical School at the request of Surgeon-General Gorgas.
