Don Baum (1922–2008) was an American curator, artist and educator, most known as a key impresario and promoter of the Chicago Imagists, a group of artists that had an enduring impact on American art in the later twentieth century. Described by the Museum of Contemporary Art, Chicago (MCA) as "an indispensable curator of the Chicago school," Baum was known for lively and irreverent exhibitions that offered fresh perspectives combining elements of Surrealism and Pop and that broke down barriers between schooled and untrained, or so-called outsider artists. From 1956 to 1972, Baum was exhibitions director at Chicago's Hyde Park Art Center. It was there, in the 1960s, that he became involved with a group of young artists he exhibited as "Hairy Who" that later expanded to become the Chicago Ima
