Bob Jackson
John Robert (Bob) Jackson started J. R. J. Cycles in Leeds, UK, in 1935, hand crafting quality racing and touring bikes until his retirement in 1986. His torch was picked up by others and the brand has survived to this day: http://www.bobjacksoncycles.co.uk/. Bob Jackson's first MTBs arrived in 1984, as custom orders. It's possible that Bob Jackson moved away from MTBs for the early 90's as no examples are easily found from 1989 → 1994.
