"Arts and Crafts History:

During the 1880s, John Ruskin, William Morris, Philip Webb, and other English designers and thinkers launched the Arts and Crafts Movement, which celebrated handicrafts and encouraged the use of simple forms and natural materials. In the United States, two California brothers, Charles Sumner Greene and Henry Mather Green, began to design houses that combined Arts and Crafts ideas with a fascination for the simple wooden architecture of China and Japan.

The name "Craftsman" comes from the title of a popular magazine published by the famous furniture designer, Gustav Stickley, between 1901 and 1916. A true Craftsman house is one that is built according to plans published in Stickley's magazine. But other magazines, pattern books, and mail order house catalogs began to publish plans for houses with Craftsman-like details. Soon the word "Craftsman" came to mean any house that expressed Arts and Crafts ideals, most especially the simple, economical, and extremely popular Bungalow.
