1879 to today: a museum built across 145 years
The Art Institute of Chicago was founded in 1879 as the Chicago Academy of Fine Arts — a private institution combining a museum and an art school, modeled loosely on the older European combined-purpose academies. The academy moved through several temporary downtown locations in its first 15 years before finding its permanent home: the Beaux-Arts main building on Michigan Avenue at Adams Street, originally constructed as the World's Congress Auxiliary Building for the 1893 World's Columbian Exposition. The Art Institute moved into the building immediately after the Exposition closed and has occupied it continuously ever since.
The original 1893 building has been expanded and modified across more than a dozen major additions across 130 years. The most recent and most significant addition is the Modern Wing, designed by Renzo Piano and opened in 2009 — a 264,000 square foot glass-and-steel structure that doubled the museum's gallery space and provided a contemporary architectural counterpoint to the historic Beaux-Arts core. The Nichols Bridgeway, a pedestrian bridge connecting the Modern Wing to Millennium Park, has become one of downtown Chicago's signature architectural moments.
The museum's school component — the School of the Art Institute of Chicago (SAIC) — remains one of the most prestigious art schools in the United States and operates as a separate but affiliated institution. Notable alumni include Georgia O'Keeffe, Walt Disney, and Jeff Koons; the school's continued operation gives the museum a working-artist character that distinguishes it from purely curatorial institutions.
