In 1878, he moved to London with his daughter, Marion for her prospective marriage to a London barrister. That summer he won an International Gold Medal at the Paris Exposition. Dana continued to paint in London, notably the famous view across the Thames to the Palace of Westminster, and Waterloo Bridge, as well as several of the pea-soup fog shrouding the river. His generic paintings included many of donkeys, on beaches, and so on, and others of animals and children. But Dana was probably best known for his seascapes, especially for a self-portrait depicting him wearing sou-wester oilskins. He exhibited at the Society of Artists in Birmingham, England.
