The Ashcan School, also called the Ash Can School, was an artistic movement in the United States during the early twentieth century that is best known for works portraying scenes of daily life in New York, often in the city's poorer neighborhoods. The most famous artists working in this style included Robert Henri (1865–1929), George Luks (1867–1933), William Glackens (1870–1938), John Sloan (1871–1951), and Everett Shinn (1876–1953), some of whom had met studying together under the renowned realist Thomas Anshutz at the Pennsylvania Academy of the Fine Arts, and others of whom met in the newspaper offices of Philadelphia where they worked as illustrators. The movement has been seen as emblematic of the spirit of political rebellion of the period.
The Ashcan School was not an organized movement. The artists who worked in this style did not issue manifestos or even see themselves as a unified group with identical intentions or career goals. Some were politically minded, and others were apolitical. Their unity consisted of a desire to tell certain truths about the city and modern life they felt had been ignored by the suffocating influence of the Genteel Tradition in the visual arts. Robert Henri, in some ways the spiritual father of this school, "wanted art to be akin to journalism... he wanted paint to be as real as mud, as the clods of horse-shit and snow, that froze on Broadway in the winter." He urged his younger friends and students to paint in the robust, unfettered, ungenteel spirit of his favorite poet, Walt Whitman, and to be unafraid of offending contemporary taste. He believed that working-class and middle-class urban settings would provide better material for modern painters than drawing rooms and salons.
Many of the most famous Ashcan works were painted in the first decade of the century at the same time in which the realist fiction of Stephen Crane, Theodore Dreiser, and Frank Norris was finding its audience and the muckraking journalists were calling attention to slum conditions. The first known use of the term "ash can art" is credited to artist Art Young in 1916. The term by that time was applied to a large number of painters beyond the original "Philadelphia Five," including George Bellows, Glenn O. Coleman, Jerome Myers, Gifford Beal, Eugene Higgins, Carl Springchorn, and Edward Hopper. (Despite his inclusion in the group by some critics, Hopper rejected their focus and never embraced the label; his depictions of city streets were painted in a different spirit, "with not a single incidental ashcan in sight.") Photographers like Jacob Riis and Lewis Hine were also discussed as Ashcan artists. Like many art-historical terms, "Ashcan art" has sometimes been applied to so many different artists that its meaning has become diluted.
