Robert Pearson McChesney was one of the Bay Area’s preeminent abstract painters. Born in Marshall, Missouri in 1913, he attended Washington University in St. Louis and completed his studies at the Otis Art Institute in Los Angeles. Moving to San Francisco in 1937, he was soon employed by the Federal Art Project painting murals for the Golden Gate International Exposition. He later assisted Anton Refregier in painting controversial murals in the Rincon Annex Post Office. He was deeply involved in the labor movement of the time, and became a merchant marine seaman. In his travels around the globe, he painted watercolors in his free time on board. This experience helped to free him from the boundaries imposed by 6 years of academic training.While teaching serigraphy at the California School of Fine Arts (now known as the SF Art Institute) in 1950-51, his colleagues included Ed Corbett, Hassel Smith, Ad Reinhardt, Mark Rothko, and Clyfford Still. The students, many of them war veterans, were generally of the same age group as the teachers, which led to a much looser, more congenial vibe than what he had experienced in his student years. In this so-called “Period of Exploration,” the cumulative talent exploded into new modes of expression, from abstract expressionism to Bay Area Figuration. Due to disgust with McCarthyism and loss of their teaching jobs, “Mac” and his wife, sculptor Mary Fuller McChesney, moved to Mexico in a Ford Model A mail truck reconfigured as a camper. En route, they spent time in Taos with Bea Mandelman and Louis Ribak, as well as San Francisco friends Ed Corbett and Richard Diebenkorn. In Mexico, Mac embarked on a new series of paintings, quite different from his previous work, dark, subtle, mystical abstractions in somber tones. When their money ran out, they moved back to the Bay Area. Given a piece of land near the top of Sonoma Mountain, they hand built their house, largely from scavenged materials. Mac then embarked on a new series, “Mountain,” one of which was purchased by the Whitney Museum. The ensuing series, “Arena,” received broad critical acclaim. After that came a series of mixed media works incorporating poured resins, bones, sisal, and other materials
