The UNC-CH Ackland museum is doing something similar, starting September 9th through December 4, and the list of artists suggests this should be, in contrast to the DC show, a doozy! From their website:
Gathered from the private collections of more than 45 alumni of The University of North Carolina at Chapel Hill, Carolina Collects: 150 Years of Modern and Contemporary Art brings together nearly 90 hidden treasures by some of the most renowned artists of the modern era.How's this for a start: Louise Bourgeois, Marsden Hartley, Thomas Hart Benton, Isamu Noguchi, George Bellows, Milton Avery, Alice Neel, Richard Diebenkorn, David Smith, Hans Hofmann, Roy Lichtenstein, Meyer Schapiro, Andy Warhol, Joan Mitchell, Jasper Johns, and Romare Bearden.
Europeans you ask? Pissarro, Monet, Renoir, Derain, Rousseau, Picasso, Max Ernst, Duchamp, Henry Moore, de Chirico, Gerhard Richter.
Photographers? Ansel Adams, Weston, Walker Evans, Sally Mann, Irving Penn.
And that is a just a partial list!
I'm particularly looking forward to the Hartley, Neel, Diebenkorn, Joan Mitchell, Bearden and Duchamp. I've never heard of Arthur Dove but this looks like a lovely piece:
