R. A. (Rainforth Armitage) Walker, aka Georges Derry (b. Congleton, Cheshire, UK 1886-d. Bedford, Bedfordshire, UK 1960) was the sub-editor of The Print Collectors' Quarterly under Campbell Dodgson (1867-1948) from 1921-36. Walker collected, compiled and published a catalogue of Aubrey Beardsley drawings, under both his names, in 1923. He donated over 50 prints and drawings to the British Museum, many through the Contemporary Art Society.
