Grandson of Thomas and nephew to Matthew Arnold, Edward joined the firm of Richard Bentley (1794–1871) in 1883 as a magazine editor before editing Murray's Magazine (1887) for J. Murray. Arnold famously declined Hardy’s Tess on Murray's behalf. Publishing in his own name from 1890, he specialized in educational books, Egyptology, exploration, and mountaineering. The firm published 1,500 titles before his retirement in 1930. Arnold's most notable author was E. M. Forster.
