American, 1931–2018. Robert Morris was an American painter who played a central role in the establishment of Minimalism, Process Art and Land Art. In one of his sculptural pieces, he played with dense felt dropping from the wall, the resulting shape creating a new sculptural format. Morris also explored the use of industrial materials, large pieces of rocks that emitted smoke, light bulbs, mirrors and textiles, creating ephemeral works that reimagined the concepts of arrangement and scale. His essay titled "Notes on Sculptures" outlined the basis of Minimalism, establishing Morris as an accomplished writer and a theorist alongside his title as a preeminent conceptual artist.
