Kilroy Was Here - Origin and Use of The Phrase

Origin and Use of The Phrase

The phrase may have originated through United States servicemen, who would draw the doodle and the text "Kilroy was here" on the walls and other places they were stationed, encamped, or visited. An ad in Life magazine noted that during World War II, "Whatever beach-head they stormed, they always found notices chalked up ahead of them, that 'Kilroy was here.'"

Brewer's Dictionary of Phrase and Fable notes that it was particularly associated with the Air Transport Command, at least when observed in the United Kingdom. At some point, the graffito (Chad) and slogan (Kilroy was here) must have merged.

An early example of the phrase being used may date from 1937, before World War II. A US History Channel video broadcast in 2007, Fort Knox: Secrets Revealed, includes a shot of a chalked "KILROY WAS HERE" dated 5/13/1937: Fort Knox's vault was loaded in 1937 and inaccessible until the 1970s, when an audit was carried out and the footage was shot. However, historian Paul Urbahns says that the footage was a reconstruction. Other sources claim origins as early as 1939.

According to one story, it was reported that German intelligence found the phrase on captured American equipment. This began leading Hitler to believe that Kilroy could be the name or codename of a high-level Allied spy. At the time of the Potsdam Conference in 1945, it was rumored that Stalin found "Kilroy was here" written in the VIP's bathroom, prompting him to ask his aides who Kilroy was. War photographer Robert Capa noted a use of the phrase at Bastogne in December 1944: "On the black, charred walls of an abandoned barn, scrawled in white chalk, was the legend of McAuliffe's GIs: KILROY WAS STUCK HERE."
