Robert Gray Murray (born March 2, 1936) is considered by some to be Canada's foremost abstract sculptor. He also has been called the most important sculptor of his generation worldwide. His large outdoor works are said to resemble the abstract stabile style of Alexander Calder, that is, the self-supporting, static, abstract sculptures, dubbed "stabiles" by Jean Arp in 1932 to differentiate them from Calder`s mobiles. Murray focused on "trying to get sculpture back to its essential form", he has said. His work is like colour-field abstraction.
