Material made from the film collection comprising of 55 items donated by Nuffield Department of Anaesthetics, Oxford, to the Wellcome Trust in 2008. In 1937, Lord Nuffield established a clinical chair of anaesthesia in Oxford amidst some controversy that anaesthesia was even an academic discipline. The collection is a mixture of clinical and educational films made or held by the department to supplement their teaching dating from the late 1930s onwards
