Charles Anderson Dana (August 8, 1819 – October 17, 1897) was an American journalist, author, and senior government official. He was a top aide to Horace Greeley as the managing editor of the powerful Republican newspaper New-York Tribune until 1862. During the American Civil War, he served as Assistant Secretary of War, playing especially the role of the liaison between the War Department and General Ulysses S. Grant. In 1868 he became the editor and part-owner of The New York Sun. He at first appealed to working class Democrats but after 1890 became a champion of business-oriented conservatism. Dana was an avid art collector of paintings and porcelains and boasted of being in possession of many items not found in several European museums.
