A group of architects and artisans who emphasized the importance of craftsmanship and high standards in all architectural details; greatly influenced by the outstanding work of William Morris and his company of craftsmen near London. Beginning in the late 19th century and extending into the early 20th century, this movement had a significant impact in America on the Prairie style with its low-pitched roofs and widely overhanging eaves, and on the Craftsman style. In particular, excellent craftsmanship and superior detailing was embraced in the designs of the architects Charles Sumner Greene (1868 1957) and his brother Henry Mather Greene (1870 1954) of Pasadena, California, whose work exemplified architectural details carried to a high art.
