Richard Diebenkorn (1922–93) was an American painter widely recognized for his contributions to both Abstract Expressionism and the development of color field painting. Born in Portland, Oregon and raised in San Francisco, California, Diebenkorn studied art at Stanford University, where his exposure to European modernism—especially the works of Matisse and Cézanne—profoundly influenced him. He served in the United States Marine Corps during World War II, and afterwards continued his studies at the California School of Fine Arts, where he initially embraced abstract painting and drew inspiration from landscapes and Abstract Expressionism. In the 1950s, Diebenkorn shifted toward figuration, creating compelling landscapes, still lifes, and figure studies characterized by a distinctive blend of structure and emotion. In 1966, he moved to Santa Monica, California and began his famed Ocean Park series, in which he developed a unique abstract language that reflected the California light and landscape. The series, which spanned over two decades, became central to Diebenkorn’s legacy as one of America's leading modern artists. In his later years in Healdsburg, California, Diebenkorn’s intimate works on paper continued to explore form and color. 

Diebenkorn’s work is held in major collections, including the Metropolitan Museum of Art and the Whitney Museum of American Art.

He exhibited at GRAY in the group show Modern and Contemporary Sculpture, 2010.
