Jack the Ripper was a serial killer who operated in London in 1888. He murdered five prostitute women in the impoverished Whitechapel neighborhood. The killer was never identified, but was reported to be a well-dressed man who frequented the dark streets of Whitechapel where many prostitutes worked. His brutal attacks involved opening the victims' bodies and leaving their internal organs exposed, demonstrating precision like a surgeon. The crimes sparked widespread fear and interest that continues today through books, films and other works about the unidentified killer.
