Artwork: Damien Hirst, The Physical Impossibility of Death in the Mind of Someone Living, 1991
Damien Hirst rose to fame as one of the Young British Artists who ruled the art scene in the UK and then found art world celebrity status in the US. Although Hirst has been a favorite in the art market, he has also been criticized by many in the art world (you tell him, David Hockney) for using assistants to make his works. Also, animal rights activists have unleashed their fury on Hirst because of his favorite medium—dead animals. While he may have been hot in the '90s, most of us are sick of the way he runs his art empire as a fine-tuned moneymaking machine.
