In the 1960s, Donald Judd proposed a new way of making and experiencing art, breaking ground in the exploration of volume, interval, space and colour. He favoured industrial materials like aluminium, Perspex, sheet metal and plywood. From the mid-1960s onward, all of his works were fabricated by skilled specialists to Judd’s precise specifications. By encouraging concentration on the volume and presence of the structure and the space around it, Judd’s work draws particular attention to the relationship between the object, the viewer, and the specific context of the object’s environment. This relationship became a central focus of Judd’s career, and he devoted much of his later life to the installation of his own work. Judd worked within an essential vocabulary of forms: ‘stacks’, ‘boxes’, and ‘progressions’.
