A. W. Andrews was a British rock-climber and mountaineer. He is especially remembered for two contributions :- for his co-authorship, with J. M. A. Thomson in 1909 of the first rock-climbing guide-book, to the cliffs of Lliwedd, in Snowdonia; and for being the 'father' of Cornish sea cliff climbing, beginning with an early ascent (1902) of the Bosigran Ridge Climb (aka Commando Ridge grid reference SW413368) followed by Ledge Climb (also Bosigran) in 1905. With E. C. Pyatt he later produced the first official (Climbers' Club) Cornish climbing guide, in 1950.
