Tax collector-turned-Post-Impressionist artist, Henri Rousseau was a self-taught painter known for his Naive works. Though it took time for his style, which was often described as simplistic and childlike, to be accepted by art critics, he helped pave the way for other talented untrained artists.

Now often referred to as Outsider art, such artists' work is considered a genre in itself, and today's Outsider artists include those using art as therapy for mental afflictions or disabilities as well as the untrained. This show features more than 100 works from artists such as Rousseau, Joan Miró, Max Ernst and Yayoi Kusama; Sept. 14-Nov. 10.
