Frederick Hammersley (1919–2009) was raised in Idaho. He moved to Los Angeles after serving in World War II to study at Chouinard Art Institute and, later, Jepson Art Institute. Though he first worked as a figurative painter, he developed a style of abstraction that incorporated biomorphic and surrealist tendencies. The crisp geometric forms in his paintings contribute to what was dubbed hard-edge painting, a style unique to Southern California that was also practiced by painters Karl Benjamin, Lorser Feitelson, John McLaughlin, and Helen Lundeberg. Hammersley was also a dedicated professor, teaching first at Jepson and later at Pomona College, Chouinard, and the University of New Mexico.
