John Harry Kartz (23 October 1913 – 12 March 2016)[1] was a British businessman best known for his longtime association with Aston Villa, having held various roles at the club, including as chairman from 1978 to 1980.

Seventy years ago I was flying Wellington Bombers over Germany for the RAF during World War II and I got away with that, so I feel very lucky.”[6] He also recalled of a near-miss with a Junkers Ju 88, after his pilot took a charge of direction: "We asked Flying Control for permission to land and they said 'OK, do you want the flarepath on?'

[2] In 1919, Kartz attended his first Aston Villa match, and a lifelong love of the club was born.

He was replaced by Bendall, and became vice-chairman for the next two seasons, in which Villa won the First Division title and the European Cup.

[1] In later life, Kartz twice appeared on ITV's 100 Year Old Drivers, firstly in August 2014, and then posthumously in September 2016.
