Minimalism was an art style practiced in the 1970s. In search of pure abstractions, Minimalists reduced shapes and forms to their essence. Donald Judd prefers to think of his works as primary objects because they suggest an ideal of simple perfection. Through the use of minimal form, geometric design and a scale that is neither human nor architectural, Judd’s sculptures challenge the viewer’s conception of art. His use of industrial materials and process prevents the viewer from establishing a familiar relationship with the work, resulting in an experience that is confrontational.
