Frederick Coffay Yohn (February 8, 1875 – June 5[1] or 6,[2] 1933), often recognized only by his initials, F. C. Yohn, was an American artist and magazine illustrator.
Yohn's work appeared in publications including Scribner's Magazine, Harper's Magazine, and Collier's Weekly. Books he illustrated included Jack London's A Daughter of the Snows, Frances Hodgson Burnett's The Dawn of a To-morrow and Henry Cabot Lodge's Story of the American Revolution. He studied at the Indianapolis Art School during his first student year and then studied at the Art Students League of New York under Henry Siddons Mowbray (1858–1928). Mowbray studied at the Atelier of Léon Bonnat in Paris. Yohn often specialized in historical military themes, especially of the American Revolution, as well as the First World War. He designed the 2-cent US Postal Service stamp in 1929 to commemorate the 150th Anniversary of George Rogers Clark's Victory over the British at Sackville. He is best known for his painting of George Washington at Valley Forge.[3]
