H. DEVITT WELSH (1888-1942) US ARMY SIGNAL CORPS. Circa 1916. 41x27 3/4 inches, 104x70 1/2 cm. Latham Litho & Ptg. Co., Brooklyn. Condition A / A-: minor creases in margins and image; repaired pin holes in corners. A battlefield reconnaissance trio (a spotter, transcriber and telegraph operator) represent the cutting edge of American military technology. Despite having a host of other responsibilities, the U.S. Signal Corps was primarily responsible for telegraphic communications. Founded during the Civil War utilizing a visual means of communication, the Corps branched out with the advent of new technology. By World War I, they were already operating telephone, telegraph and early radio transmissions from the field. Rawls p. 55, Theofiles 5.
