1851–1910
**William St. John Harper (1851–1910)** was an American painter, etcher, illustrator, and influential teacher active primarily in New York City and its environs, including East Hampton. Born in Rhinebeck, New York, he attended the College Grammar School in Brooklyn before pursuing art.
Harper received his earliest training from John Whittaker at the Brooklyn Academy of Design. Between 1872 and 1875 he studied antique and life classes at the National Academy of Design under Thomas Le Clear and Lemuel Wilmarth, earning an honorable mention in life drawing during his first year there. He later traveled to Paris, where he worked with Léon Bonnat and Mihály Munkácsy. In New York he became one of the founding organizers of the Art Students League, serving as both a teacher and its president in 1881; he also instructed at Cooper Union, the Newark Technical School, and other institutions, and briefly acted as art director for the *New York Daily Graphic*. He was elected an Associate of the National Academy of Design in 1892.
Harper worked across media, producing landscapes, genre scenes, and especially etchings and illustrations. One notable example is his 1886 etching *The Conversation*, signed in pencil and based on a painting by Alfred Stevens. His drawings, watercolors, and oils from the 1890s–1900s survive in private collections and auction records, reflecting a practical, illustrative approach suited to both fine art and commercial reproduction.
Harper’s legacy rests as much on his teaching and institutional leadership as on his individual works. By helping establish and lead the Art Students League he helped shape a generation of American artists during a period of growing professionalization in the arts. He died in New York City in 1910.
