The moniker associated with the unidentified serial killer operating in London’s Whitechapel district in 1888, “Jack,” likely stemmed from the killer’s own boastful claim. It first appeared in a letter purportedly sent by the murderer to the Central News Agency. This letter, known as the “Dear Boss” letter, was signed “Jack The Ripper.”
The adoption of this specific appellation proved significant. It rapidly captured the public imagination, feeding into existing anxieties about societal breakdown and the perceived threat posed by the impoverished East End. The simplicity and immediacy of the name helped to solidify the figure into a menacing and readily identifiable boogeyman, amplified by sensationalized press coverage.
