Sam Francis
Francis returned to California during the 1960s and continued painting in Los Angeles.   During the final three decades of his career his style of large scale bright Abstract Expressionism was also closely associated with Color Field painting.  During the last year of his life, suffering from prostate cancer and unable to paint with his right hand after a fall, in a final burst of energy he used his left hand to complete a dazzling series of about 150 small paintings before he died.  He was buried in Olema, in Marin County, California.
