Robert Rauschenberg worked in a wide range of mediums including painting, sculpture, prints, photography, and performance, over the span of six decades.

In 1951, the 28-year-old artist Ellsworth Kelly submitted a grant to the Guggenheim Foundation, proposing “an alphabet of plastic pictorial elements, aiming to establish a new scale of painting, a closer contact between the artist and the wall, providing a way for painting to accompany modern architecture.

Two exhibitions in 1962 announced Andy Warhol’s dramatic entry into the art world. In July, at the Ferus Gallery in Los Angeles, he exhibited his now-iconic Campbell’s Soup Cans .

A key figure in the Pop art movement and beyond, Roy Lichtenstein grounded his profoundly inventive career in imitation—beginning by borrowing images from comic books and advertisements in the early 1960s, and eventually encompassing those of everyday objects, artistic styles, and art history itself.
