Robert George Gilberg (1911–1970) was a painter, printmaker and educator whose work ranged from landscapes to abstraction. Born in Oakland, California, he studied at the Oakland Art Center during the 1930s before serving in the U.S. Army during World War II. He subsequently settled in Nevada City, where the Sierra Nevada landscape became an important source of artistic inspiration. Working in watercolor, gouache, encaustic and other media, Gilberg explored the expressive possibilities of color, form and natural imagery, moving between recognizable subjects and increasingly abstract compositions. His work was exhibited in San Francisco in 1941 and 1942, at the California Watercolor Society between 1946 and 1953, and at the California State Fair in 1957. Gilberg's artistic achievements were recognized by Wayne Thiebaud, who contributed the foreword to the catalog accompanying the artist’s 1971 memorial exhibition at Sacramento's Artists Contemporary Gallery.
