Donald Judd (1928-1994) had a rigorous visual vocabulary that sought clear and definite objects as its primary mode of articulation. His sculptures offer insight into his singular commitment to material, colour, and proportion. Judd is one of the most significant American artists of the postwar period and his works have come to define what has been referred to as Minimalist art, (a label to which the artist strongly objected on the grounds of its generality). The work of Donald Judd is included in numerous museum collections. Permanent installations of the artist’s work can be found at Judd Foundation spaces in New York City and Marfa, Texas, along with the neighbouring Chinati Foundation.
