 First published in the "Pall Mall Christmas "Extra"" in December 1884, its characters were based on criminals in the employ of real-life surgeon Robert Knox (1791–1862) around the time of the notorious Burke and Hare murders (1828).
Edward Theodore Gein ( ; August 27, 1906 – July 26, 1984), also known as The Butcher of Plainfield, was an American murderer and body snatcher.

 Gein confessed to killing two women – tavern owner Mary Hogan in 1954, and a Plainfield hardware store owner, Bernice Worden in 1957.
 Gein was initially found unfit to stand trial and confined to a mental health facility.
 In 1968, Gein was found guilty but legally insane of the murder of Worden, and was remanded to psychiatric institutions.
 He died at Mendota Mental Health Institute of cancer-induced liver and respiratory failure at age 77 on July 26, 1984.
