Irvine Welsh was born in Edinburgh, Scotland. Raised in the tenement homes of Leith, the prefabs in West Pilton and the maisonettes in Muirhouse, he attended Ainslie Park Secondary School. At sixteen, he left education and took on various jobs, and eventually moved to London in the seventies. There he dabbled with the property market while spending his free time exploring the London punk scene. He then moved back to Edinburgh to study an MBA.
Back home, and inspired by the nineties rave scene, he was fortunate enough to run into some fascinating characters whom he immortalised in his diary – and, later, in the pages of Trainspotting. At first dismissed for its unmarketable content, Trainspotting shot Welsh to fame, precipitated further by the release of the film, by Danny Boyle, three years later.
Since then he has written eight other works of fiction. He currently lives in Chicago.
