A result of the industrial age was a short-lived but powerful new American art movement called Precisionism, most evident in painting, but visible also in drawing, photography, and print-making, focusing on industrial and mechanical subjects. Precisionism originated in the 1920s, allied with European Cubism's fascination with shape and geometric form and with Italian Futurism's emphasis on the details of modern cities. The movement was important to a growing interest in modern art and its evolution away from strict realism. The Precisionists chose to depict the 20th century's new dependence on technology and the machine in a way that celebrated the efficiency and promise of industrial work: the style created clearly defined, even idealized images of industrial subject matter including factories, machinery, and the people who operated them. American Precisionist artists, with their celebratory images of progress, also reflected a pride in their country during a period of economic and political struggle--the growing industry in the United States was a symbol of the country's power and achievements. Precisionism lasted until after World War II, when the modern art movement it had helped to foster went on to abstraction and non-representational subjects. This article explores four Precisionist artists' images of their contemporary world in four different two-dimensional media (photography, oil paint, conte crayon, and print-making). Each artwork is introduced with discussion questions and the resource ends with art activities based on an understanding of all four images. Students who complete the lessons will be able to: (1) Identify which of several images presented to them are Precisionist and which are not, and give reasons for their selections; (2) Describe the subject matter that is and is not included in Precisionist images, based on the four examples; (3) Define "Industrial Revolution" and cite at least two changes industrialization caused in American society; and (4) Explain the connection between the Industrial Revolution and the subjects and styles of the art of four American artists: Lewis W. Hine, Charles Demuth, Charles Sheeler, Edward A. Wilson.
