Louis Sullivan

Louis Sullivan (1856–1924) was an American architect known as the father of modern architecture and the skyscraper. Born in Boston, he studied at MIT and the École des Beaux-Arts in Paris before partnering with Dankmar Adler in Chicago. Together they designed landmarks like the Auditorium Building and Wainwright Building. Sullivan coined the phrase "form follows function" and mentored Frank Lloyd Wright. In his later years, he designed a celebrated series of small-town Midwestern banks — his "jewel boxes" — bringing extraordinary ornamental artistry to prairie communities.
