Arthur Harold Moss (November, 1889 in Greenwich Village – February 20, 1969 in Neuilly-sur-Marne) was an American expatriate poet and magazine editor.
His parents were German-Jewish and Turkish immigrants. After serving in World War I, he attended Cornell University for three years, but dropped out.
In 1917, he returned to Greenwich Village, founding The Quill with partner Harold Hersey and was managing editor and wrote articles. It included artists Clara Tice, Wood Gaylor, Mark Toby and Alfred J Frueh; writers included Ben De Casseres.
He married Millia Davenport (1895–1992) and worked with her at The Quill. They co-authored, The Quill: For And By Greenwich Village, vol.4, no.8, 1919. They separated shortly thereafter. She went on to design costumes, and in 1948 wrote The Book of Costume. In 1920, he hired his future wife Florence Gilliam to edit Quill. In 1921 they moved to Paris, into a small apartment near Shakespeare & Company, the bookstore owned by Sylvia Beach.
In August 1921, they began publishing Gargoyle, an intense literary magazine. Gargoyle published reproductions of Henri Matisse, Pablo Picasso, André Derain, Amedeo Modigliani, Paul Cézanne. Writers contributing to the publication included Ezra Pound, Robert Coates, Malcolm Cowley, Hart Crane, Stephen Vincent Benet, Hilda Doolittle and Sinclair Lewis. Without outside backing and lacking a subscriber base, in October 1922, Gargoyle ceased publication. For the next few years Arthur would write a column for the New York Times and the Paris Herald.
