Jonah Barrington (squash player)  Jonah Barrington (born 29 April 1941) is a retired Irish/English squash player, originally from Morwenstow, Cornwall, England. A Cornish-born Irish squash player, Barrington won the British Open (which was considered to be the effective world championship event before the World Open began) six times between 1967 and 1973, and was known as "Mr. Squash".

Jonah now coaches Egyptian world no.1 and 2015 British Open champion Mohamed El Shorbagy. One of his ancestors, Sir Jonah Barrington, established an estate in County Limerick called "Glenstal", which was eventually sold in the 1930s to a group of Belgian Benedictine monks who established a boarding school. In 1982 Barrington co-authored the book "Murder in the Squash Court: the Only Way to Win". He has coached Israeli squash player Daniel Poleshchuk. Barrington is the father of professional squash player Joey Barrington.
