Between The World Wars
There was substantial SIGINT work between the World Wars, although the secrecy surrounding it was extreme. While it was primarily COMINT, ELINT emerged with the development of radar.
Both sides developed direction-finding (DF) and communications interception stations during the war, although those programs often began with naval search & rescue.

Famous quotes containing the words world and/or wars:
“I have lived in both worlds. And I think I prefer, to the indifferent, haphazard, money- mad hurry of the Outside World, that of my world; that sympathy and understanding grown shadowy since I have been away from it so long, still is more real to me than the world I am in now. Not only the spangles and the gay trappings made it colorful; there was an inner color that warmed the soul. And that I miss.”
—Josephine Demott Robinson (1865–1948)
“Wars and revolutions and battles are due simply and solely to the body and its desires. All wars are undertaken for the acquisition of wealth; and the reason why we have to acquire wealth is the body, because we are slaves in its service.”
—Socrates (469–399 B.C.)
