Origin
There was no such figure recorded in history named Jack Robinson who was quick on his feet and hence gained reputation through this phrase. At one point in time there was a Sir John Robinson who was the guard of the Tower of London who would behead inmates at a record speed but historians believe that the phrase was coined before his time. Jack Robinson seems to be a made up figure like Santa Claus or Jack Frost. In 1778, Mme. Frances D'Arblay, used this phrase in her work which was a romantic novel.
