Art in the Twenty-First Century

Part 3 (of four) profiles Bruce Nauman, Maya Lin, Louise Bourgeois and Kerry James Marshall, “four contemporary artists who deal in notions of identity,” says Steve Martin, who introduces the hour. Marshall uses black themes in his paintings and installations; the 90-year-old Bourgeois, a sculptor, frequently fashions hands; Lin, renowned for her Vietnam War Memorial, is seen “[taking] an idea of sculpture and grow[ing] it into a park” in Grand Rapids, Mich. And Nauman makes psychologically infused videos and installations, one of which is an outdoor stairway. “A stairway is a work of art,” he says, “because I said so.”
