Question: How long did the founder of Stratton Oakmont spend in prison ?
Context: Adam de Stratton (died 1292–94) was a royal moneylender, administrator and clergyman under Edward I of England.  He advanced professionally through the patronage of the earls of Devon, and became Chamberlain of the Exchequer and steward of Isabella, Countess of Devon.  At the same time he made himself an enormous fortune through moneylending, primarily by acquiring debts from Jewish moneylenders.  His business methods were dubious, and often involved various illegal activities.  In 1290 he fell victim to an investigation of corruption in the royal administration, and from 1292 until his death—no later than 1294—he was held in prison.  Stratton has been called by a modern historian "the greatest and probably the most unscrupulous of thirteenth-century money lenders, who eventually met the fate he deserved." Jordan Ross Belfort ( ; born July 9, 1962) is an American author, motivational speaker, and former stockbroker.  In 1999, he pleaded guilty to fraud and related crimes in connection with stock-market manipulation and running a boiler room as part of a penny-stock scam.  Belfort spent 22 months in prison as part of an agreement under which he gave testimony against numerous partners and subordinates in his fraud scheme.  He published the memoir "The Wolf of Wall Street", which was adapted into a film and released in 2013. Daniel Mark Porush (born February 1957) is an American entrepreneur and former stock broker who is known for his supervision of a "pump and dump" stock fraud scheme in the 1990s.  In 1999, as the president of Stratton Oakmont brokerage house, Porush was convicted of securities fraud and money laundering, for which he served 39 months in prison.  The character of Donnie Azoff in the popular 2013 film "The Wolf of Wall Street" was loosely based on Porush.

Alfred Edward Stratton (born 1882) and his brother Albert Ernest Stratton (born 1884, both executed at 9am on 23 May 1905 at HM Prison Wandsworth) were the first men to be convicted in Great Britain for murder based on fingerprint evidence.  The case, otherwise known as the Mask Murders (due to the black stocking-top masks that had been left at the scene of the crime), the Deptford Murders (due to the location) or the Farrow Murders (the last name of the victims), was one of the earliest convictions using forensic science.

The Wolf of Wall Street is a 2013 American biographical black comedy crime film directed by Martin Scorsese and written by Terence Winter, based on the memoir of the same name by Jordan Belfort.  It recounts Belfort's perspective on his career as a stockbroker in New York City and how his firm Stratton Oakmont engaged in rampant corruption and fraud on Wall Street that ultimately led to his downfall.  Leonardo DiCaprio (who was also a producer) stars as Belfort, with Jonah Hill as his business partner and friend Donnie Azoff, Margot Robbie as his wife Naomi Lapaglia and Kyle Chandler as Patrick Denham, the FBI agent who tries to bring him down.  Matthew McConaughey, Rob Reiner, Jon Favreau, Joanna Lumley and Jean Dujardin also star.  The film marks the director's fifth collaboration with DiCaprio, after "Gangs of New York" (2002), "The Aviator" (2004), "The Departed" (2006) and "Shutter Island" (2010), as well as his second collaboration with Winter after the television series "Boardwalk Empire" (2010–14).
