Sir Melville Leslie Macnaghten was Assistant Commissioner (Crime) of the London Metropolitan Police from 1903 to 1913. A highly regarded and famously affable figure of the late Victorian and Edwardian eras he played major investigative roles in cases that led to the establishment and acceptance of fingerprint identification. He was also a major player in the pursuit and capture of Dr. Crippen, and of the exoneration of a wrongly convicted man, Adolph Beck, which helped lead to the creation of the Court of Criminal Appeal in 1907.

Jack the Ripper was an unidentified serial killer active in and around the impoverished Whitechapel district of London, England, in 1888. In both criminal case files and the contemporaneous journalistic accounts, the killer was also called the Whitechapel Murderer and Leather Apron.
