Every roster of history’s notorious psychopaths mentions Jack the Ripper. In 1888, he terrorized London’s Whitechapel district by stalking and murdering a string of prostitutes under the cover of fog. This killer became famous, in large part, because his identity remains unknown. The name "Jack the Ripper" originated in a letter, written by someone claiming to be the murderer, which was disseminated in the media. The removal of internal organs from at least three of the victims led to proposals that their killer possessed anatomical or surgical knowledge. An investigation into a series of brutal killings in Whitechapel up to 1891 was unable to connect all the killings conclusively to the murders of 1888 but the legend of Jack the Ripper solidified. As the murders were never solved, the legends surrounding them became a combination of genuine historical research, folklore and pseudo-history. The term "Ripperology" was coined to describe the study and analysis of the Ripper cases. There are now over one hundred theories about the Ripper's identity, and the murders have inspired multiple works of fiction. In addition to the contradictions and unreliability of contemporary accounts, attempts to identify the real killer are hampered by the lack of surviving forensic evidence. DNA analysis on extant letters is inconclusive; the available material has been handled many times and is too contaminated to provide meaningful results. This video describes the details of the case 'Jack the Ripper'.
