Duveneck, Frank, original name of Frank Decker (1848-1919), American painter, etcher, and teacher, who had a great influence on American art. Born in Covington, Kentucky, he studied art in Munich from 1870 to 1873. He returned to Munich in 1875 and in 1878 and established an art school there, which followed him to Florence and Venice. Duveneck returned to the United States in 1888. His bold, dark, and loosely painted portraits were in the style of the Munich school. Included among his pupils were the Americans William Chase and John Twachtman. In 1900 Duveneck joined the faculty of the Art Academy of Cincinnati. His most famous painting is The Whistling Boy (1872, Cincinnati Art Museum).
