Voyage to France In the early 1790s, concerned at the likelihood of war between Britain and France, Matthews travelled to France with the radical
David Williams, who was acquainted with such
Girondins as
Jacques Pierre Brissot and
Charles-François Lebrun. Williams made efforts at mediation which failed, whereupon Matthews took the lead. He gained the trust of the French government for a short time. On 2 June 1793 the Girondists were displaced by the
Jacobins and Matthews fell under suspicion for his Girondist associations and also because he was suspected of being a
double agent. He was arrested and imprisoned for three years during the height of
The Terror and was reportedly terrified of the guillotine, like all others. This lasted until 1796 when the French authorities concluded that he was a
lunatic and released him.
Committal Returning to London, Matthews wrote two letters to
Lord Liverpool, in which he accused the
Home Secretary of treason and complained about conspiracies directed against his life. After interrupting a debate in the
House of Commons by shouting "Treason" at Lord Liverpool from the Public Gallery, he was arrested and held at
Tothill Fields Bridewell, a secure
house of correction in Tothill Fields,
Westminster before being admitted to the
Bethlem (Bedlam) hospital on 28 January 1797. In 1809 his family and friends petitioned for his release, on the grounds that he was no longer insane, but their petition was rejected by the Bethlem authorities. They therefore took out a suit of
habeas corpus and two doctors,
George Birkbeck and
Henry Clutterbuck examined Matthews, declaring him sane.
John Haslam, the resident
apothecary at Bethlem, begged to differ and maintained that Matthews'
delusions, particularly on political matters, rendered him a danger both to public figures and the general public. Haslam intended to settle the dispute over Matthews' sanity; his book contains verbatim accounts of Matthew's beliefs and hallucinatory experiences and is considered the original description of the symptoms of paranoid schizophrenia. The book documented the first full study of a single psychiatric patient in medical history and has become a classic in the medical literature.
The "Air Loom" Matthews believed that a gang of criminals and spies skilled in
pneumatic chemistry had taken up residence at
London Wall in
Moorfields (close to Bethlem) and were tormenting him by means of rays emitted by a machine called the "Air
Loom" or gaseous charge generator. The torments induced by the rays included "Lobster-cracking", during which the circulation of the blood was prevented by a
magnetic field; "Stomach-skinning" and "Apoplexy-working with the nutmeg grater" which involved the introduction of fluids into the skull. His persecutors bore such names as "the Middleman" (who operated the Air Loom), "the Glove Woman" and "Sir Archy" (who acted as "repeaters" or "active worriers" to enhance Matthews' torment or record the machine's activities) and their leader, a man called "Bill, or the King". Matthews' delusions had a definite political slant: he claimed that the purpose of this gang was espionage, and that there were many other such gangs armed with Air Looms all over London, using "pneumatic practitioners" to "premagnetize" potential victims with "volatile magnetic fluid". According to Matthews, their chief targets (apart from himself) were leading government figures. By means of their "rays" they could influence ministers' thoughts and
read their minds. Matthews declared that William Pitt was "not half" susceptible to these attacks and held that these gangs were responsible for the British military disasters at
Buenos Aires in 1807 and
Walcheren in 1809 and also for the
Nore Mutiny of 1797. In 1814 Matthews was moved to "Fox's London House", a private asylum in
Hackney, where he became a popular and trusted patient. His delusions appeared to have stopped. The asylum's owner, Dr. Fox, regarded him as sane. Matthews assisted with bookkeeping and gardening until his death on 10 January 1815. ==Significance of the Air Loom Gang affair==
