John French Sloan (August 2, 1871 - September 8, 1951) was an American artist.
He was born in Lock Haven, Pennsylvania., to a businessman father and a schoolteacher mother. At the age of 20, he became an illustrator with The Philadelphia Inquirer. He studied art in the evening at the Pennsylvania Academy of the Fine Arts, where he met his mentor, Robert Henri, author of The Art Spirit.
Sloan's style was heavily influenced by European artists of the late 19th and early 20th century. He was familiar with Van Gogh's work, as well as Picasso, and Matisse, and several of his works appear as if they are a fusion of European styles.
Sloan moved to Greenwich Village in New York, where he painted some of his best-known works, including McSorley's Bar, Sixth Avenue Elevated at Third Street and Wake of the Ferry. In later years, he spent summers working and painting in Gloucester, Massachusetts, and Santa Fe, New Mexico.
He was allied with the Ashcan School and a member of The Eight, a group of American realist artists that included Robert Henri, Everett Shinn, Arthur B. Davies, Ernest Lawson, Maurice Prendergast, George Luks, and William J. Glackens. One of his students was Norman Raeben.
