Louis Sullivan – 1856-1924

Sullivan was a brilliant late 19th century architect generally regarded as the father of modern architecture and the first great architect to tackle the skyscraper. His leading principle was to ensure that the form of a structure followed its function and was organic to the building, rather than a matter of mere decoration. His early masterpieces were produced in partnership with the Dankmar Adler and include the Auditorium Building, Chicago (1866-1889) and the Wainwright Building, St. Louis (1890– 1891). Frank Lloyd Wright was Sullivan’s apprentice.
