Charles Dudley Warner (September 12, 1829 - October 20, 1900) was an American essayist, novelist, and friend of Mark Twain, with whom he co-authored the novel The Gilded Age: A Tale of Today. Warner was born of Puritan descent in Plainfield, Massachusetts. He worked with a surveying party in Missouri and then studied law at the University of Pennsylvania. He moved to Chicago, where he practiced law from 1856 to 1860, when he relocated to Connecticut to become assistant editor of The Hartford Press. By 1861 he had become editor, a position he held until 1867, when the paper merged into The Hartford Courant and he became co-editor with Joseph R. Hawley.
