Proto-fantasy novelist and pre-Raphaelite William Morris is the father of the Arts & Crafts movement (my favorite architectural and decorative style), and his textiles and wallpapers were wildly popular in Victorian homes and today are ubiquitous in yuppie remodels and with set dressers creating interiors of the period (partly because they are probably the best-known designs of the period and are widely available because his company, Morris & Co, is still printing his designs from the original wooden blocks. They were not nearly as widespread as you'd think from tv and movies of recent years though, nor have they ever been affordable enough to be).
