Arthur William Symons (28 February 1865 – 22 January 1945), was a British poet, critic and magazine editor.
Born in Milford Haven, Wales, to Cornish parents, Symons was educated privately, spending much of his time in France and Italy. In 1884–1886 he edited four of Bernard Quaritch's Shakespeare Quarto Facsimiles, and in 1888–1889 seven plays of the "Henry Irving" Shakespeare. He became a member of the staff of the Athenaeum in 1891, and of the Saturday Review in 1894, but his major editorial feat was his work with the short-lived Savoy.
His first volume of verse, Days and Nights (1889), consisted of dramatic monologues. His later verse is influenced by a close study of modern French writers, of Charles Baudelaire, and especially of Paul Verlaine. He reflects French tendencies both in the subject-matter and style of his poems, in their eroticism and their vividness of description. Symons contributed poems and essays to The Yellow Book, including an important piece which was later expanded into The Symbolist Movement in Literature, which would have a major influence on William Butler Yeats and T. S. Eliot. From late 1895 through 1896 he edited, along with Aubrey Beardsley and Leonard Smithers, The Savoy, a literary magazine which published both art and literature. Noteworthy contributors included Yeats, George Bernard Shaw, and Joseph Conrad. Symons was also a member of the Rhymer's Club founded by Yeats in 1890.
