John Angelo Jackson (21 March 1921 – 2 July 2005) was an English mountaineer, explorer and educationalist.
He was brought up and educated in Nelson, Lancashire. Before World War II, he was apprenticed in pharmacy. However, at the outbreak of war, he left to volunteer for the R.A.F. in which he served for six years. He flew with No. 31 Squadron RAF in India and Burma, flying in much needed supplies to the 14th Army who were stranded behind Japanese lines, for which he was mentioned in despatches.
After the war he became a schoolmaster. He taught geography and science in Nelson and Redcar, during which time he would voluntarily undertake extracurricular activities after school hours and weekends introducing his students to the mountains.
He was an avid and skilful photographer, something that lasted throughout his life, much of this work was used on lecture tours around the world, books that he wrote, pictures and detailed information for books that other people requested for their publications, magazine articles, the BBC etc.
He started climbing on the Yorkshire Moors, and later moved to the Lake District and Scotland. His experience as a first-class rock climber was crucial to becoming Instructor and later Chief Instructor at the RAF Mountaineering Centre at Sonamarg in Kashmir.
Within the public engagement framework rules laid down by the CCPR that effectively prevented him from actually sitting on committees of external bodies, he extensively guided major governing bodies, i.e. the B.M.C and M.L.T.B, to become involved with all aspects of "Outdoor Pursuits", not solely the climbing aspects.
With the assistance of a grant made by the then Sports Minister Dennis Howell, he was able to build the canoe training pool, extend the dry ski slope and provide a Bar which added greatly to the existing facilities of the Centre.
Wrote extensively for many magazines and journals, e.g. Climber and Rambler, The Great Outdoors, The Himalayan Club, The Fell and Rock Journal and the Alpine Journal.
