The Anaesthesia Heritage Centre contains the Association of Anaesthetists archives, museum and rare book collection. The archives date from the foundation of the association in 1932 and record its development. The museum contains objects relating to the history of anaesthesia, resuscitation and pain relief – the earliest object being a resuscitation set dating from 1774. Permanent displays include pull-out drawers and flipbooks containing biographies of key individuals and details of anaesthetic machines. An exhibition about pain relief's progress during the first half of the twentieth century, 'A Silver Lining Through the Dark Clouds Shining: the Development of Anaesthesia During the First World War', will be on display until Early July 2015, and focuses on the pioneering work of Geoffrey Marshall and Henry Edmund Gaskin Boyle. As the Centre is small, advance booking is advised.
