The Museum of Anaesthesia at the Association of Anaesthetists in Portland Place, is a unique medical museum devoted to the history of anaesthesia and pain relief. The museum is free to visit and open to all Monday-Friday.

The Museum was founded from a donation by A Charles King but has since embraced numerous contributions. The collection encompasses the entire history of anaesthesia, from the first recorded demonstration of ether inhalation in 1846, to modern anaesthetic machines and appliances still in use today.

An archive and library provide excellent facilities for research into the history of anaesthesia.
