Jack the Ripper
Jack the Ripper is a pseudonym given to an unidentified serial killer (or killers) active in the largely impoverished Whitechapel area and adjacent districts of London in the latter half of 1888. The name is taken from a letter to the Central News Agency by someone claiming to be the murderer, published at the time of the killings. The legends surrounding the Ripper murders have become a combination of genuine historical research, conspiracy theory and folklore. The lack of a confirmed identity for the killer has allowed Ripperologists — the term used within the field for the authors, historians and amateur detectives who study the case — to accuse a wide variety of individuals of being the Ripper.
