James Shields

James Shields (21 November 1918 – 20 June 1978) was a Scottish psychiatric geneticist and twin researcher. In the 1960s, he worked with Irving Gottesman on a twin study of schizophrenia at the Medical Research Council Psychiatric Genetics Unit at Maudsley Hospital in London, England. This study, known as the Maudsley twin study, is now considered a landmark in the field. He had previously begun working for Eliot Slater at Maudsley after serving in the United Kingdom's Royal Artillery during World War II. He was a fellow of the Eugenics Society and the International Society for Twin Studies.
