Frank Duveneck (dyōō´vənĕk), 1848–1919, American portrait and genre painter and teacher, b. Covington, Ky., studied in Cincinnati and in Munich. In 1875 he showed a group of his canvases in Boston, where they created a sensation because of their bold brushwork, rich color, and forceful presentation of personality. He taught for many years in Munich and, after 1889, in Cincinnati. His influence on his contemporaries was great, particularly on William Chase and his followers and on the ashcan school. His Whistling Boy (Cincinnati Art Mus.) and Old Woman (Metropolitan Mus.) are characteristic of his portrait studies.
