Which minimalist artist is famous for his stacked aluminum boxes?

Donald Judd is the Minimalist artist famous for his stacked aluminum boxes.

Judd developed his signature boxlike forms in the 1960s, using industrial materials such as aluminum, steel, Plexiglas, and plywood. Many works consist of repeated units placed on walls, floors, or in vertical stacks. Their plain geometry and serial repetition make the objects seem less like handmade sculpture and more like precise, self-contained structures.

The boxes are commonly called “specific objects,” a term connected with Judd’s effort to move beyond traditional categories such as painting and sculpture. He often worked with professional fabricators, allowing clean surfaces, exact proportions, and consistent repetition. Color, reflection, spacing, and the surrounding room all contribute to how the works are experienced.

The other names in the choices are associated with Minimalism but are not the canonical answer. Tony Smith is known for large geometric steel sculptures, Robert Morris for modular objects and installations, and Sol LeWitt for serial structures and conceptual wall drawings. Judd’s repeated aluminum boxes remain among the movement’s most recognizable forms.
