Ronald Melzack

Ronald Melzack, OC OQ FRSC (born July 19, 1929, Montreal, Quebec) is a Canadian psychologist and emeritus professor of psychology at McGill University. In 1965, he and Patrick David Wall revolutionized pain research by introducing the gate control theory of pain.In 1968, Melzack published an extension of the gate control theory, in which he asserted that pain is subjective and multidimensional because several parts of the brain contribute to it at the same time.
