(1876-1949): Educated at the Chicago Art Institute and the Art Students League in New York, Clark also studied in Paris for two years. He moved to Pasadena around 1920. During World War I he served as one of the first aerial photographers. He took up mural painting shortly after his arrival in southern California, although he primarily considered himself a landscape painter. He taught at Occidental College and was director of the Stickney Memorial School of Art in Pasadena. He painted murals for the Carthay Circle Theater in Los Angeles, but the theater was demolished during the 1960s because it wasn't earthquake safe.
