John William Tinn (20 January 1878 - 13 March 1971)[1] was an English football manager.
In 1919, the year South Shields were selected for the Football League Second Division, Tinn was named manager of the team.
[2] Under Tinn's stewardship Portsmouth won the FA Cup for the first time in their history when they beat Wolverhampton Wanderers 4-1 at Wembley in 1939.
Although Tinn departed in 1947 he is still credited with creating the great Pompey side which went on to win back-to-back league championships in 1949 and 1950.
[3] Tinn reportedly stored the FA cup under his bed during WWII, along with other unusual storage locations.
