Harriet and Walter Pratt, of Minneapolis, focused their collecting on the German, Austrian, Belgian, and Russian artists who broke with convention in the early 1900s, eschewing realism in favor of emotion. The artists’ exuberant use of color and line became known as Expressionism, the defining art movement of the early 20th century. In 2021, the Pratts bequeathed the 19 works in this exhibition to Mia, including paintings and drawings by Vassily Kandinsky, Gabriele Münter, and Lyonel Feininger, as well as a marble bust of a young woman by Erastus Dow Palmer, a prominent 19th-century sculptor and Harriet’s great-grandfather.
