"Richard Whittington (c. 1354–1423) was a medieval merchant and politician, and the real-life inspiration for the pantomime character Dick Whittington. Richard Whittington was Lord Mayor of London and a Member of Parliament. ...

... Dick Whittington is a character in a British pantomime, very loosely based on Richard Whittington. There are several versions of the traditional story, which tells how Dick, a boy from a poor family, sets out for London to make his fortune, accompanied by his cat."
