Louise Sullivan is known as the father of modern architecture. His most popular works were done in the late 18 – early 19th century. This building, The Wainwright Building in St. Louis, MO, was built in 1891. It is known as the first sky scrapper that “really looked the part” and it set the standard for all modern skyscrapers to follow. The most prominent parts of this building are the surfaces around the main door, the designs under the windows at each floor, and the frieze right below the roof.
