Jones was born in London, England, the son of a Welsh carpenter-builder, and took a first-class Honours degree in experimental physics.
Although Jones said little in his writings about his training tactics – other than working with dumbbells – there are several stories regarding his gymnastic feats.
[1] He jokingly called himself "the Only Genuine Jones", and was famous at Wasdale Head in the Lake District for his gymnastic stunts around the inn.
Crowley also criticised his "lunging for holds", thought him a self-publicist, and was disdainful of Jones teaming up with "two photographers".
Although he used an ice axe advantageously at the bottom for a step, as well as "combined tactics" (probably a shoulder stand) – accepted practices at the time – this was an impressive ascent.
