Chad
The figure was initially known in Britain as "Mr Chad". Chad would appear with the slogan "Wot, no sugar", or a similar phrase bemoaning shortages and rationing. He often appeared with a single curling hair that resembled a question mark and with crosses in his eyes. The phrase "Wot, no —?" pre-dates "Chad" and was widely used separately from the doodle. Chad was used by the RAF and civilians; in the army Chad was known as Private Snoops, and in the Navy he was called The Watcher. Chad might have first been drawn by British cartoonist George Edward Chatterton in 1938. Chatterton was nicknamed "Chat", which may then have become "Chad." Life Magazine in 1946 said that the RAF and Army were competing for claiming him as their own invention, but they agreed that he had first appeared around 1944. The character resembles Alice the Goon, a character in Popeye who first appeared in 1933; another name for Chad was "The Goon".
A theory suggested by a spokesman for the Royal Air Force Museum London in 1977 was that Chad was probably an adaptation of the Greek letter Omega, used as the symbol for electrical resistance; his creator was probably an electrician in a ground crew. Life suggested that Chad originated with REME, and noted that a symbol for alternating current, a sine wave through a straight line, resembles Chad, that the plus and minus signs in his eyes represent polarity, and that his fingers are symbols of electrical resistors. The character is usually drawn in Australia with pluses and minuses as eyes and the nose and eyes resemble a distorted sine wave. Similarly, The Guardian noted in 2000 that several readers had told them that "Mr. Chad" was based on a diagram representing an electrical circuit. One correspondent said that in 1941 at RAF Yatesbury a man named Dickie Lyle drew a version of the diagram as a face when the instructor had left the room, and wrote "Wot, no leave?" beneath it. This idea was repeated in a submission to the BBC in 2005 that included a story of a 1941 radar lecturer in Gainsborough, Lincolnshire drawing the circuit diagram, and the words "WOT! No electrons?" being added. The RAF Cranwell Apprentices Association says that the image came from a diagram of how to approximate a square wave using sine waves, also at RAF Yatesbury and with an instructor named Chadwick, and was initially called Domie or Doomie, the latter name also being noted by Life as used by the RAF. As alternatives to Chatterton or Mr Chadwick as the origin of the name Chad, REME claimed that the name came from their training school, nicknamed "Chad's Temple", the RAF claimed it arose from Chadwick House at a Lancashire radio school, and the Desert Rats claimed it came from an officer in El Alamein.
It is unclear how Chad gained widespread popularity or became conflated with Kilroy. It was, however, widely in use by the late part of the war and in the immediate post-war years, with slogans ranging from the simple "What, no bread?" or "Wot, no char?" to the plaintive; one sighting, on the side of a British 1st Airborne Division glider in Operation Market Garden, had the complaint "Wot, no engines?" The Los Angeles Times reported in 1946 that Chad was "the No. 1 doodle", noting his appearance on a wall in the Houses of Parliament after the 1945 Labour election victory, with "Wot, no Tories?" Trains in Austria in 1946 featured Mr. Chad along with the phrase "Wot—no Fuehrer?"
As rationing became less common, so did the joke; while the cartoon is occasionally sighted today as "Kilroy was here", "Chad" and his complaints have long fallen from popular use, although they continue to be seen occasionally on walls and in references in popular culture. It is a common misconception that the graffiti was tied to the Berlin Wall, "Chad" long pre-dated the wall.
