“In 1879, Sullivan entered the Chicago office of architect and engineer Dankmar Adler, becoming his full partner in 1883. Together, Adler and Sullivan designed nearly two hundred residential, commercial, religious, and mixed-use buildings, primarily in the Midwest. Adler and Sullivan were highly regarded not only for their robustly modern and iconoclastic architecture—which illustrated Sullivan’s dictum “form follows function”—but for Sullivan’s complex and organic ornament. Their best-known buildings include the Auditorium Building in Chicago (1886-1890); the Wainwright building in Saint Louis, Missouri (1886-1890); the Schiller Building (1891) and the Stock Exchange (1893-1894) buildings, both in Chicago; and the Guaranty building in Buffalo, New York (1894-1895). It was also during this time that Sullivan became the leibermeister of Frank Lloyd Wright, who worked for Adler and Sullivan from 1888 to 1893.”
