Robert Indiana was born Robert Clark in New Castle, Indiana on September 13, 1928. Adopted as an infant, he spent his childhood moving frequently throughout his namesake state. His artistic talent was evident at an early age, and its recognition by a first grade teacher encouraged his decision to become an artist. In 1942, Indiana moved to Indianapolis in order to attend Arsenal Technical High School, known for its strong arts curriculum. After graduating he spent three years in the U.S. Air Force and then studied at the Art Institute of Chicago, the Skowhegan School of Sculpture and Painting in Maine, and the Edinburgh College of Art in Scotland.

In 1956, two years after moving to New York, Indiana met Ellsworth Kelly, and upon his recommendation took up residence in Coenties Slip, once a major port on the southeast tip of Manhattan. There he joined a community of artists that would come to include Kelly, Agnes Martin, James Rosenquist, and Jack Youngerman. The environment of the Slip had a profound impact on Indiana’s work, and his early paintings include a series of hard-edge double ginkgo leaves inspired by the trees which grew in nearby Jeannette Park. He also incorporated the ginkgo form into his nineteen-foot mural Stavrosis (1958), a crucifixion pieced together from forty-four sheets of paper that he found in his loft. It was upon completion of this work that Indiana adopted the name of his native state as his own.
Indiana, like some of his fellow artists, scavenged the area’s abandoned warehouses for materials, creating sculptural assemblages from old wooden beams, rusted metal wheels, and other remnants of the shipping trade that had thrived in Coenties Slip. While he created hanging works such as Jeanne d’Arc (1960–62) and Wall of China (1960–61), the majority were freestanding constructions which Indiana called “herms” after the sculptures that served as boundary markers at crossroads in ancient Greece and Rome.

The discovery of nineteenth- century brass stencils led to the incorporation of brightly colored numbers and short emotionally charged words into these sculptures as well as canvases, and became the basis of his new painterly vocabulary.
