 Together with Johannes Larsen, Poul S. Christiansen and Fritz Syberg, Hansen was one of the first Funen artists to study under Zahrtmann, leaving the traditions of the Danish Academy and venturing into Naturalism and Realism.Initially adopting Zarhtmann's approach but soon influenced by Philipsen's Impressionism, Hansen became one of the finest Colourists of his day.Most of his works are genre paintings inspired by country scenes from both Funen and Italy.
