The U.S. Army Signal Corps began in 1860, with the appointment of Dr. Albert J. Myer, a physician, as Chief Signal Officer. Under his command, the unit transformed sign language used to communicate with deaf persons into a semaphore system incorporating red and white "wigwag" flags. During the Civil War, the Signal Corps operated air balloons and telegraph machines. By the time the United States entered World War I in 1917, the corps had integrated the airplane and more advanced technology into its communications systems. In World War II, the Signal Corps' size and role in military affairs increased dramatically. From a staff of 27,000 persons, it expanded to over 350,000 men and women by 1945. The need to coordinate swift and accurate communication for air, ground, and naval units required more sophisticated technology and services. The Signal Corps pioneered in the development of radar to detect approaching aircraft as well as mobile communications and deciphering machines.
