Gordon Coster (1906, 25 February – 1988) was a commercial photographer who worked in Chicago for a major portion of his mature career. During the 1930s Coster began documenting labor union activities, and those of anti-fascist and peace movements. From 1941 to 1955, Coster was frequently commissioned by Life magazine. He was solicited by Edward Steichen to join a group of photographers who were documenting World War II for the U.S. Navy. Today, Coster’s work is viewed as representative of the development of pictorialist, documentary and early modernist movements in photography.
