Q: The Mildred Lane Kemper Art Museum, established in 1881, is one of the oldest teaching museums in the country. The collection includes works from 19th, 20th, and 21st century American and European artists, including George Caleb Bingham, Thomas Cole, Pablo Picasso, Max Ernst, Alexander Calder, Jackson Pollock, Rembrandt, Robert Rauschenberg, Barbara Kruger, and Christian Boltanski. Also in the complex is the 3,000 sq ft (300 m2) Newman Money Museum. In October 2006, the Kemper Art Museum moved from its previous location, Steinberg Hall, into a new facility designed by former faculty member Fumihiko Maki. Interestingly, the new Kemper Art Museum is located directly across from Steinberg Hall, which was Maki's very first commission in 1959.
