D.W. Winnicott (1896-1971) was the first paediatrician in Britain to train as a psychoanalyst. In over forty years of clinical practice at the Paddington Green Children's Hospital, he brought unprecedented skill to the relatively new discipline of the psychoanalysis of children. His work is increasingly being regarded as one of the most influential contributions to psychoanalysis since Freud. His wife, Clare, was a renowned social worker.
