Michael Antony Denborough (1929 – 2014) was an Australian anaesthetist, academic, politician and medical researcher.
First described malignant hyperthermia (Maladie de Denborough)
Co-founder of Nuclear Disarmament Party in 1984. He is known to have maintained a solo vigil outside the parliament house in Canberra (Australia) for a total of 52 days against the war in Iraq. He was arrested twice in his lifetime; once in 1991 for protesting at an arms bazaar and second time outside the French Embassy after the French government resumed their nuclear tests in the Pacific.
In 2003 he was dismissed from Parliament for protesting loudly in the gallery when John Howard (Australian Ex-Prime Minister) committed Australian troops for the Iraq invasion.

Maladie de Denborough (1960) (malignant hyperthermia)
In April 1960, at the Royal Melbourne Hospital, anaesthetist Dr Jim Villiers treated a patient who was understandably terrified as 10 members of his family had died during other minor procedures involving general anaesthesia. The patient, a 21-year-old engineering student had suffered a compound fracture of his right tibia and required general anaesthesia for the open reduction and internal fixation to be performed. Dr. Villiers decided to administer halothane and utilise all available monitors at the time. Whilst the fracture was quickly reduced and closed, the patient developed tachycardia, hypotension, hypoxemia and hyperthermia. Dr. Villiers initially thought this may be due to blood loss from the fracture and the patient was given a blood transfusion. Subsequently as the patient deteriorated Dr. Villiers packed the patient in ice being used in a nearby cardiac theatre and the patient was awake and alert with an eventful subsequent hospital stay. While his patient did develop signs of what we now refer to as Malignant Hyperthermia, Dr Villiers was able to save him from the fate of his other relatives with his skilled anaesthetic management.
Dr Michael Denborough and his colleague Dr Richard Lovell then went on to study this patients family in greater detail. They outlined the autosomal dominant inheritance of this severe reaction to anaesthetics and their letter was published in The Lancet. Dr Denborough went on to devote most of his career to research in the field of malignant hyperthermia.

- “In 1970 Michael came across evidence of an increase of radioactive iodine uptake in sheep’s thyroid glands every time the French conducted a nuclear test in the Pacific. When the politicians refused to act on this information he and his medical colleague Roger Melick wrote a press release and sent it to all the national newspapers. The Australian public was horrified and the outburst led to the matter being taken up by the newly elected Gough Whitlam. He then sent his attorney-general Lionel Murphy to the International Court in the Hague and that forced the French nuclear tests underground.5“
- “Michael’s activism continued throughout the years. He was arrested for protesting at AIDEX (an arms bazaar) in 1991 and then again in the mid 90s outside the French Embassy after the French government resumed their nuclear tests in the Pacific.5“
- “In 2003 when the US invaded Iraq he set up a solo vigil outside Parliament House in Canberra and stayed for 52 days. On the day Howard committed Australian troops to Iraq he got thrown out of Parliament for protesting loudly from the gallery.5“
