Damien Hirst (born 7 June 1965) is an English artist and the most prominent of the group that has been dubbed "Young British Artists" (or YBAs), says Wikipedia.
Hirst dominated the art scene in Britain during the 1990s and is internationally renowned. During the 1990s his career was closely linked with the collector Charles Saatchi, but increasing frictions came to a head in 2003 and the relationship ended.
Death is a central theme in Hirst's works. He became famous for a series in which dead animals (including a shark, a sheep and a cow) are preserved—sometimes having been dissected—in formaldehyde. His most iconic work is The Physical Impossibility of Death in the Mind of Someone Living, a 14-foot (4.3 m) tiger shark immersed in formaldehyde in a vitrine. Its sale in 2004 made him the world's second most expensive living artist after Jasper Johns.
In June 2007, Hirst overtook Jasper Johns when his Lullaby Spring sold for £9.65 million at Sotheby's in London. On 30 August 2007, Hirst outdid his previous sale of Lullaby Spring with For The Love of God which sold for £50 million to an unknown investment group.  He is also known for "spin paintings," made on a spinning circular surface, and "spot paintings," which are rows of randomly-coloured circles.
In September 2008, he took an unprecedented move for an artist of his status by selling a complete show, Beautiful Inside My Head Forever, at Sotheby's by auction and by-passing his long-standing galleries, The auction exceeded all predictions, raising £111 million ($198 million), breaking the record for a one-artist auction as well as Hirst's own record with £10.3 million for The Golden Calf, an animal with 18-carat gold horns and hooves, preserved in formaldehyde.
