Abstract
The pathologist David Stark Murray was a founder and leading member of the Socialist Medical Association , an organization affiliated to the Labour Party and instrumental in shaping its health policy in the period up to 1945. Murray played a prominent role in the SMA as a member of its Executive Committee and as Editor of its journal MedicineToday and Tomorrow. This article examines Murray's popular writings about science during the interwar period, focusing on his emphasis on the relationship between, on the one hand, scientific knowledge and scientific method; and, on the other, a socialized health service and a socialist society
