Hirst was born in Bristol and grew up in Leeds, moving to London in 1986 to study at Goldsmith's College. While still a student, he organised the enormously successful 'Freeze' exhibition, which featured his own work as well as that of fellow students. This brought him to the attention of the highly influential art collector Charles Saatchi and is generally seen as the starting point for the 'Young British Artists' movement. The central theme of Hirst's work is mortality. He is best known for the 'Natural History' series of works, in which dead animals are preserved in tanks. He is also interested in medical paraphernalia and has produced series of spot paintings, spin paintings and steel and glass cases.
