Frank Lloyd Wright spent the first 20 years of his 70 year career in Oak Park, building numerous homes in the community, including his own. He lived and worked in the area between 1889 and 1909. One can find Wright's earliest work here like the Winslow House in neighboring River Forest, Illinois. There are also examples of the first Prairie-Style houses in Oak Park. There were several well-known architects and artists that worked in Wright's Oak Park Studio. Richard Bock, William Eugene Drummond, Marion Mahony Griffin, and Walter Burley Griffin each contributed to Wright's work during this time. Innumerable buildings in Oak Park were built by other Prairie School architects such as Tallmadge and Watson, George W. Maher, Robert C. Spencer, John Van Bergen, and E.E. Roberts.
