John Gilmore Marshall, known as Jack Marshall, (born 29 May 1917, Bolton, Lancashire, died 1 January 1998, Rotherham, South Yorkshire), was a footballer and football manager, who played for Burnley, and managed Rochdale, Blackburn Rovers, Sheffield Wednesday and Bury.
He managed Blackburn Rovers for seven years during which time "Jolly" Jack, a nickname given him by some of the players, led the team (nicknamed "Marshall's Misfits"), to the top of the old First Division. This feat that would not be repeated until the investment by Jack Walker in the 1990s.
