WALTER REED.
In the year 1900, Major Walter Reed, a surgeon in the United States Army, demonstrated, by experiments conducted in Cuba, that a mosquito of a single species, Stegomyia fasciata, which has sucked the blood of a yellow-fever patient may transmit the disease by biting another person, but not until about twelve days have elapsed. He also proved, as described in Volume I, Part II, that the malady is not contagious. "With the exception of the discovery of anæsthesia," said Professor Welch, of Johns Hopkins University, "Dr. Reed's researches are the most valuable contributions to science ever made in this country." General Leonard Wood declared the discovery to be the "greatest medical work of modern times," which, in the words of President Roosevelt, "renders mankind his debtor." Major Reed died November 23, 1902.
