William Calcraft (11 October 1800 – 13 December 1879) was a 19th-century English hangman, one of the most prolific of British executioners. It is estimated in his 45-year career he carried out 450 executions. A cobbler by trade, Calcraft was initially recruited to flog juvenile offenders held in Newgate Prison. While selling meat pies on streets around the prison, Calcraft met the City of London's hangman, John Foxton.
