The Lidwill machine was designed by Mark Lidwill in 1913, for the purpose of mechanical or insufflation anaesthesia. It was manufactured by Elliott Bros. of Sydney. Shortly afterwards, the Anaesthetic and Portable Machine Company of Sydney devised a machine that was functionally the same but also contained an electric lamp heater.Colour photograph of a modified Lidwill anaesthetic machine sitting on carpet, taken from above.

In 1913, Mark Cowley Lidwill designed a machine for the purpose of mechanical or insufflation anaesthesia. The Lidwill machine was a portable machine weighing 7kg that could easily be packed into two small bags. The machine involved compressed air being delivered to an ether vaporiser. An ether/air control device allowed varying concentrations of ether to be delivered. The ether vaporiser could be immersed in hot water to prevent cooling and the ether temperature was measured. From the vaporiser, the ether/air mixture went through a trap bottle, then to a crude mercury blow-off valve and subsequently to the patient.Large leather suitcase style bag divided into two levels containing and insufflation anaesthesia machine.insufflation, mark cowley lidwill, thoracic surgery, positive pressure

Mark Cowley Lidwill was awarded an Honorary Fellowship in 1954 after his retirement to honour his working life.Mark Cowley Lidwill was born in England in 1878. His family moved to Melbourne in 1894. Lidwill studied medicine at the University of Melbourne, graduating with honours in 1902 and achieving a Doctorate in Medicine (MD) in 1905. Soon after graduation he moved to Sydney and in 1913 was appointed as the first lecturer in anaesthetics at the Royal Prince Alfred Hospital. That year Lidwill became the first person in the world to catch a black marlin with rod and reel. The event was celebrated in newspapers throughout the country and the marlin skeleton is now on display at the Australia Museum. Lidwill was also the designer of a machine which could deliver anaesthesia mechanically. Compact and portable, the machine delivered precise, although variable, concentrations of ether. Lidwill is also credited with developing the world’s first pacemaker. In a letter he wrote to Harry Daly in 1955, Lidwill was ambivalent about the fate of the machine: “No one would be bothered with it and they thought I was mad”.Printed certificate from the Faculty of Anaesthetists of the Royal Australasian College of Surgeons (RACS) awarded to Mark Cowley Lidwill as an Honorary Fellowship.
