Ralston Crawford (1906–1978) was an American abstract painter, lithographer, and photographer.
Crawford was best known for his abstract representations of urban life and industry. His early work placed him with Precisionist artists like Niles Spencer and Charles Sheeler. Here, the focus was on realistic, sharp portrayals of factories, bridges, and shipyards. Later work was geometrically abstract. In Spain, he observed bullfighting, and the religious procession during Holy Week in Seville. In New Orleans, he painted and photographed cemeteries and jazz musicians (requiring a permit to visit bars normally restricted to blacks). Fortune Magazine sent Crawford to the Bikini Atoll in 1946 to record a nuclear weapons test.
During his abstract period, he said, "I don't feel obligated to reveal the forms. They may be totally absent to the viewer of the work, or even to myself, but what is there, however abstract, grows out of something I have seen. I make pictures."
