Donald Judd – American post-war artists who changed the face of sculpture. His monolithic structures that challenged the established forms of sculpture. He rejected the tradition of artistic expression and craftsmanship by using industrial materials such as Plexiglas, sheet metal and plywood, and from the mid-1960s his works were fabricated by external manufacturers. His work informs us about art, light, architecture and politics. What a genius one of my favourite sculpturers.
