A contrasting ideology based on the Arts and Crafts movement, which focused on guiding society back to a simpler, healthier, and more organic lifestyle, developed in Chicago during the years 1900-1915. Architect Frank Lloyd Wright and his followers developed the Prairie School characterized by distinct horizontal elements such as low-hipped roofs, overhanging eaves and bands of windows. Ornamentation tends to be abstract geometric patterns. In Wilmette, the Frank J. Baker House at 507 Lake Avenue (1909) is a work by Frank Lloyd Wright that is listed on the National Register of Historic Places. The Ralph S. Baker House at 1226 Ashland Avenue (1914) by William Drummond and the Alfred Bersbach House at 1120 Michigan Avenue (1914) by John S. Van Bergen are also excellent examples of the Prairie Style.
