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.

[1] Warner traveled widely, lectured frequently, and was actively interested in prison reform, city park supervision, and other movements for the public good.

First published as a series in The Hartford Courant, these sketches were popular for their abounding and refined humor and mellow personal charm, their love of the outdoors, their suggestive comment on life and affairs, and their delicately finished style, qualities that suggested the work of Washington Irving.

Called The Gilded Age: A Tale of Today, it gave that era of American history its name.

[5] He died in Hartford on October 20, 1900, and was interred at Cedar Hill Cemetery, with Mark Twain as a pall bearer and Joseph Twichell officiating.
