Robert Henri (25 June 1865 – 12 July 1929) was an American painter and teacher. He was a leading figure of the Ashcan School in art.
In Philadelphia, Henri began to attract a group of followers who met in his studio to discuss art and culture, including several illustrators for the Philadelphia Press newspaper who would become known as the 'Philadelphia Four': William Glackens, George Luks, Everett Shinn, and John French Sloan. The gatherings became known as the "Charcoal Club", featuring life drawing and readings in the social philosophy of Ralph Waldo Emerson, Walt Whitman, Émile Zola, and Henry David Thoreau. By 1895, Henri had come to reconsider Impressionism, calling it a "new academicism".
For several years, he divided his time between Philadelphia and Paris, where he met the Canadian artist James Wilson Morrice. Morrice introduced Henri to the practice of painting pochades on tiny wood panels that could be carried in a coat pocket along with a minimal kit of brushes and oil. This facilitated the kind of spontaneous depictions of urban scenes which would come to be associated with his mature style.
