James Robertson (1911–1988) was a psychiatric social worker and psychoanalyst based at the Tavistock Clinic and Institute, London from 1948 until 1976. John Bowlby said of him, "(He) was a remarkable person who achieved great things. His sensitive observations and brilliant observations made history, and the courage with which he disseminated – often in the face of ignorant and prejudiced criticism – what were then very unpopular findings, was legendary. He will always be remembered as the man who revolutionised children's hospitals, though he accomplished much else besides. I am personally deeply grateful for all that he did."
