Iain Sinclair (born 11 June 1943 in Cardiff, Wales) is a British writer and film maker. Much of his work is rooted in London, most recently within the influences of psychogeography.
Sinclair was for some time perhaps best known for the novel Downriver (1991), which won the James Tait Black Memorial Prize and the 1992 Encore Award. It envisages the UK under the rule of the Widow, a grotesque version of Margaret Thatcher as viewed by her harshest critics, who supposedly establishes a one party state in a fifth term. The volume of essays Lights Out for the Territory gained Sinclair a wider readership by treating the material of his novels in non-fiction form. His essay 'Sorry Meniscus' (1999) ridicules the Millennium Dome. In 1997, he collaborated with Chris Petit, sculptor Steve Dilworth, and others to make The Falconer, a 56 minute semi-fictional 'documentary' film set in London and the Outer Hebrides about the British underground filmmaker Peter Whitehead.
One of his most recent works and part of a series focused around London is the non-fiction London Orbital; the hard cover edition was published in 2002, along with a documentary film of the same name and subject. It describes a series of trips he took tracing the M25, London's outer-ring motorway, on foot. Sinclair followed this with Edge of the Orison, a psychogeographical reconstruction of the poet John Clare's walk from Dr Matthew Allen's private lunatic asylum, at Fairmead House, High Beach, in the centre of Epping Forest in Essex, to his home in Helpston, near Peterborough. Sinclair also writes about Claybury Asylum, another psychiatric hospital in Essex, in Rodinsky's Room, a collaboration with the artist Rachel Lichtenstein.
Much of Sinclair's recent work consists of an ambitious and elaborate literary recuperation of the so-called occultist psychogeography of London.
In 2008 he wrote the introduction to Wide Boys Never Work the London Books reissue of Robert Westerby's classic London low-life novel.
